1. Introduction
This users’ manual is to provide necessary information to the users of 8mφ Space Chamber (referred to as“this facility” hereafter) located in the Space Simulation Test Laboratory.
This facility is used for “thermal vacuum tests” to verify the thermal design and environmental durability ofsatellites in simulated space environments on ground.
The major environments in outer space are high vacuum, cryogenic shade, intensive solar radiation, etc. On
the geostationary orbit which is about 36,000 km above the surface of the earth, those environments reach thelevels of about 10-11 Pa with high vacuum, 3K with cryogenic shade being an infinite heat absorber, and 1.4
kw/m2 with solar radiation which is about twice the intensity of that on the earth’s surface.
However, it is financially unfeasible to simulate such environments on ground as they are, and therefore thisfacility provides vacuum pressure of 1.3×10-3 Pa or less, shroud temperature of 100K or lower, and solar
radiation of up to 2.2 kw/m2 simulated by Xenon lamps.
While this facility is unable to simulate the actual environments imposed on satellites to verify theirenvironmental durability, we can still verify the reliability of satellite behaviors in space by extrapolating themfrom the accuracy assessment on thermal designs under the simulated environments mentioned above.

2. Brief Overview of this Facility
2.1. System Outline
This facility consists of a vacuum vessel system that includes a vertical cylindrical self-supported typevacuum vessel as its main constituent, a vacuum equipment system made up of different kinds of vacuum pumps,
an LN2 system composed of a shroud that is cooled down to 100K or lower by liquid nitrogen, etc., a solar
simulation system and an IR heater system for simulating thermal input, e. g., solar energy, for a test specimen(■abbreviated as TS hereafter), a measurement and control system that monitors and controls the entire spacechamber, a TS supporter to mount and set a TS in the chamber, and a common system consisting of a cold watersupply unit and an instrument air package.
The system/tree diagrams of 8mφ Space Chamber Facility are shown in Figures 2-1 and 2-2, respectively.
Also, the external views of the access door and the vacuum vessel are shown in Figures 2-3 and 2-4, respectively.

・ Calorimeters are to be set, connected, and removed by users.
・ Contact the operation company of the facility with the information on the S/N and connection channelsof the installed calorimeters.
・ The final checking of calorimeter settings (calorimeter S/N, conductance values, channels for opticalreceiver/disc temperature measurement, etc.) in the data acquisition system is to be completed by users
without fail.
(7) TQCM (Thermoelectric Quartz Crystal Microbalance)
TQCM monitors contamination during a thermal vacuum test.

model #: MK-10 (sensor), M-1900 (processor), M-1800A (controller)
manufacturer: QCM Research Corp.

Note) Cautions for using TQCM
・ Only one line in this facility is dedicated to the connection of a TQCM. When using 2 or more TQCMs,
use P05 (DC100V/5A line) for connecting them.
・ When using TQCM with its HEAT PUMP (Peltier device) turned on, use it at – 110℃ or higher.

Caution(1) The chamber is equipped with some connectors, etc., shown in Table 3-1 as accessories, which can beleased (except for MS3106B22-22S.) They are, however, shared by the 6mφ Radiometer Space Chamber
and the 13mφ Space Chamber, and therefore previous confirmation is necessary to make sure they are notbeing used by other facilities.
(2) The socket contacts for thermocouples are crimp-type, and are therefore not reusable. Users are to preparethem by themselves. It may take 2 ~ 3 months before the date of delivery depending on the stock status of
manufacturers.
(3) The inner-vessel permanent terminal boards in the 8mφ Space Chamber do not become cryogenic, andtherefore their connectors do not have to be made of Teflon.

3.3. TS Supporter(1) TS dolly
A TS dolly mounts a TS such as a satellite, etc., to move and place it inside the chamber. The surfaceof the dolly in the visual field range from a TS is covered with a shroud just as the chamber is. Also, thelocations of the hard points which are the I/F to a TS are common to those of the 13mφ Space Chamber
and the 6mφ Radiometer Space Chamber, which suggests compatibility among the facilities. A TS
weighing up to 4,000 kg can be mounted on the dolly. Its dimensions and external view are shown in
Figures 3-7 and 3-8, respectively.
(2) Hard points for mounting TS
Those hard points help fixing a TS directly inside the chamber without using a TS dolly. With a dolly,
the height from the upper planes of the rails to the tops of the fixing hard points is 425 mm, while it can beshortened to 40 mm by means of the TS-mounting hard points equipped on the chamber floor. Each hardpoint can withstand an item weighing up to 2,000 kg. Figure 3-9 shows a drawing of hard points for
mounting a TS.
There also are metal hangers for a TS on the shroud at the height of 6,500 mm from the rails upper
planes. Each hanger can suspend an item weighing up to 1,000 kg. For the details of their locations, refer
to Figure 3-9.

3.4. LN2/GN2 Supply Ports for TS
There are five LN2/GN2 supply ports for a TS in this facility. They are lined up next to the LN2 ports forcooling a TS dolly in the left back of the floor in the vacuum vessel (cf. Figure 3-9.)
They supply LN2 from the storage tank and GN2 from the evaporator, whose flow rates are controlled by theautomatic valves in the valve box for a TS installed on the 1st floor of the chamber (the supply lines cannot be
individually designated for LN2 or GN2.)
It is not necessary to take procedures based on the High Pressure Gas Safety Law when using LN2/GN2 for a
TS (that is, they are not classified as high pressure gas facilities.) However, valves other than the pre-installed
automatic valves are not to be installed, because they could cause sealed liquid.
The LN2/GN2 supply ports are connected via Grayloc Connectors, and therefore users are to pay attention to
the following matters when laying pipes by themselves.
(1) The hubs and seal rings of Grayloc Connectors are to be prepared by users.
(2) Since it normally takes 3 months to have the hubs of Grayloc Connectors procured (seal rings also takelong for procurement), users are to confirm with the manufacturer (Nikkiso Co., Ltd.) for the procurement
lead time when they plan for laying pipes. The LN2/GN2 supply/return ports for a TS are shown in Table
3-9. Also, the I/F connector for a Grayloc Connector is depicted in Figure 3-10.

3.5. Building
Refer to Figure 3-11 for the locations of the rooms and cranes in the building. A TS is carried in via the routeof the unpacking room (1F) → the lifting room (1F) → the 2nd preparation room (3F) → the 1st preparation
room (3F.) The layout of the rooms along the route, as well as of the cranes, are shown in Figure 3-12.
Moreover, the route of carrying in the test devices, etc., for a TS is the chamber room (1F) → the test
measurement room (3F.) The locations and specifications of the cranes, which are 1t hoist cranes, are shown in
Figure 3-11 and Table 2-5, respectively.

3.5.1. Unpacking Room
A TS, jigs, etc., are to be carried into the facility from the unpacking room. In the course of that, make sure thatthe shutter of the unpacking room facing the lifting room is to be kept closed while the opposite shutter to theatmosphere is open to carry in a TS; then in turn, the latter shutter is to be closed while a TS is carried into the liftingroom.
3.5.2. 1st Preparation Room/2nd Preparation RoomThe 1st /2nd preparation rooms are available to users as their working area for a test in the chamber.

43

This may not be the latest edition.

3.5.3. Distribution Boards Facility for Tests
As the power supplies for users, UPS output relay terminal boards are being installed. The details on their voltage,current capacity, grounding, etc., are shown in Table 3-10.

Max. total output capacity: 30 kVA (including about 2 kVA for the facility)
backup time: 10 min or longer

3.5.4. Test Measurement Room
The test measurement room can be used as the users’ anteroom. Users can bring in test devices for a TS, etc.,
and set them in this room. Be cautious, though, not to place concentrated load on the floor when bringing in an
item weighing 300 kg or more.
The room also has a whiteboard, which enables users to hold a meeting there.

The starting time for atmosphere return is to be scheduled at either 11:00 or 23:00.

4.2. General Description of Tests (for reference)In this facility, environmental tests, e. g., solar radiation thermal balance/thermal vacuum tests, IR radiation
thermal balance/thermal vacuum tests, etc., can be performed. The general description of each environmental test
is provided below. The environmental conditions for each test are described in Table 4-1.
(1) Solar radiation thermal balance/thermal vacuum test
A thermal balance test confirms the thermal design, etc., of a TS in the high vacuum and cryogenic
temperature that simulate outer space, while a thermal vacuum test confirms the environmental resistanceof equipment, etc., mounted on a TS to the thermal environment in space, that is, high and low temperatures
and the back-and-forth transition between them. Solar simulators are used as the heat sources.
(2) IR radiation thermal balance/thermal vacuum test
A thermal balance test and a thermal vacuum test are performed for the same purposes as of solar
radiation tests, adopting IR lamps or heaters as the heat sources.

4.3. Power Failure Protective Measures
The general flow of measures against momentary power interruption or power failure is shown in Figure 4-2.
(1) Momentary power interruption(a) The cryopump and the solar simulator system are aborted at the momentary power interruption of asecond or shorter. The instrument air compressor is also aborted, but has no influence on the actionsof automatic valves, owing to the automatic back-up by GN2.
(b) The abort of the cryopump due to momentary power interruption raises the inner-chamber pressure up
to around 9×10-5 Pa, but not to the range where discharge is likely to take place, which suggests thatdischarge prevention measures are not necessarily to be taken by the TS side as long as the momentary
power interruption lasts no longer than a second.
(c) The solar simulator system aborted due to momentary power interruption is reactivated in about 20 ~30 minutes, fully recovering the state where it can apply solar radiation again.
(2) Power failure(a) In the power failure of a second or longer, all the mechanical vacuuming pumps, e. g., cryosorption
pumps, etc., are aborted, except for the cooler for shrouds and scavenger cryopanels. Then, it is to be
determined whether to keep cooling the shrouds to avoid rapid pressure raise or stop cooling them byintroducing GN2, based on the power failure duration and the state of excessive cooling protection
measures being taken for a TS. (Generally, continuous cooling of shrouds is chosen while waiting for
power recovery.)(b) A 30 kVA UPS is prepared in the UPS room for users. It is recommended that the heater systems (e. g.,
power supply for heat sources) wished to be heated during power failure or the checkout devices, etc.,
wished to be controlled and monitored during power failure be connected to the UPS in advance (thepower supply cables between a UPS and the power supply for heat sources are prepared by the facility
side.) Refer to section 3.5.3 for how to connect the UPS for users.
(c) The control device, data processing device, a remote setting PC for the power supply for heat sources,
communication system, and oximeter are connected to a UPS (uninterruptible power supply) which
can supply power for 10 minutes or longer.

51

This may not be the latest edition.

(d) After about 10 minutes of power failure, the emergency power generator in the power building ofTsukuba Space Center starts supplying EP. Its pre-activation stand-by time and EP capacity varydepending on the state of its application by other facilities and equipment.
(e) In case power failure is not recovered for 10 minutes or longer, the saved data is to be stored in theexternal medium to make provision for hard disc failure due to the forced termination of the dataacquisition system (measurement can be continued.)(f) The power supply from the emergency power generator in the power building of Tsukuba Space Center
is finite. Therefore, unnecessary lights or devices are to be turned off while the emergency power
generator is supplying EP, for the sake of saving EP to the extent possible.
(g) Once the emergency power generator in the power building of Tsukuba Space Center starts to supply
EP, the inner-chamber pressure can be maintained at about 9×10-5 Pa with the help of vacuuming by
cryosorption pumps and turbo molecular pumps. Figure 4-3 shows the pressure transition inside thechamber when power failure lasts for 20 minutes, with EP started to be supplied from the emergency
power generator in the power building of the Tsukuba Space Center after 10 minutes from theoccurrence of power failure. (Bear in mind that the pressure transition varies widely depending on the
power failure duration.)(h) Without the recovery of power failure for 15 minutes or longer, or the power supply from theemergency power generator after 10 minutes from the occurrence of power failure, the inner-chamberpressure reaches the range which is generally considered as susceptible to discharge (1.3×10-3 Pa) in
about 15 ~ 20 minutes. As soon as power failure takes place, therefore, take discharge prevention
measures by shifting the operational mode of a TS into the launch mode, for example.
(3) Power restoration(a) A momentary power interruption takes place at the moment of power restoration when power supply
shifts from the emergency power generator in the power building of Tsukuba Space Center to theregular power supply. Therefore, power restoration is informed to users via simultaneous broadcastingin the building or via contact from the facility-side personnel, to urge users to turn off the equipment
not connected to a UPS for a moment.

4.4. Matters to be Confirmed for Test (Important)Once vacuumed, the environment in the space chamber is the same as outer space in that it cannot be accessed
promptly. Bearing that in mind, the following matters are to be checked.
(1) Matters concerning chamber contamination
・ Whether or not anything with high steam pressure or susceptibility to evaporation from heating is usedin the chamber.
・ Whether or not commercial products that are not made for the usage in space are being used. (Are there
commercially available glues or adhesive tapes being used?)・ Is the applied material less likely to generate outgas?
・ For the purpose of preventing any phenomenon that can influence on test environments, e. g.,
degradation of vacuum levels, etc., users of the facility are to make a list of articles that are brought
into this space chamber facility by themselves (example: TS, jigs, feed-through terminals, cables, etc.)
and submit it at a kickoff meeting (K/O) with the results of prior confirmation on each of the articles
in the form “List of Articles Brought into Chamber by Users” shown in Table 4-2.
(2) Matters concerning vacuum
・ Whether or not there is gas leakage from gas-sealed equipment.
・ Whether or not there is any chance that MLI might block vent holes (See if MLI does not cover thevent holes of tanks, etc.)
・ Whether or not MLI has vent holes, or one end of it is not fixed.
・ Whether or not there is a problem when inner or outer pressure is loaded.
・ Whether or not the vacuum seals on vacuum seal connectors have been closely inspected.
・ Whether or not leakage has been thoroughly inspected in case the vacuum vessel has any feed-throughequipment (waveguide, tube, etc.)

54

This may not be the latest edition.

(3) Harmful effects of low temperature
・ Whether or not the material has low temperature brittleness that can cause a problem.
・ Whether or not the risks of low temperature brittleness or outgas are deeply taken into account whenpolymer material (rubber, etc.) is used in the parts that become cold.
・ Whether or not there is any item whose temperature won’t go up readily during normal temperature
atmosphere return. If there is any, it is to be checked if it is equipped with any mechanism to raise its
temperature.
・ Whether or not a fluid is freeze-proven, if it is planned to be used.
(4) Matters concerning vacuum discharge
・ Electric discharge is generally said to take place in the pressure range around 1.33 × 10-3 ~ 1.33 ×
104Pa, where loading of high voltage may damange a TS due to electric discharge (cf. JERG-2-130HB005 Handbook of Thermal Vacuum Test, section 3.7.1.)
・ It is required that the electric-discharge-hazardous pressure range be determined by the TS side andreported to the facility-side personnel in advance.
・ It is to be confirmed that loading of voltage is avoided in the electric-discharge-hazardous pressure
range, or discharge prevention measures are taken in case that is not possible.
(5) Considerations for high pressure gas safety law
・ The LN2/GN2 pipes for a TS in this facility are not subject to the High Pressure Gas Safety Law. Whenusers prepare an LN2 panel, etc., make sure they do not correspond to the regulated objects of the law(no valves, no sealed liquid, etc.)(6) The I/F to the facility is to be checked not only by a drawing, but also by visual observation on it.
・ I/F to TS supporter(The hard ports being made of SUS304, users are to watch out for “seizure” if they prepare screws thatare SUS products)
・ I/F to LN2 systems
・ I/F to solar simulator flax
・ I/F to inner-chamber protruding objects (sensors, tubes, etc.), etc.
・ Table 4-3 “Requirement for Facility” is to be submitted at the K/O meeting.
・ Emergency stop switches are installed on the door shroud, the 1st preparation room, and the monitor &control room. Users are to make sure of their actual locations. The appearance of an emergency stop
switch in the vacuum vessel (installed on the door shroud) and where the switches are located areshown in Figures 4-4 and 4-5, respectively.
