2.  **Responsibilities**

During PHENIX operations there will be two levels of responsibility for
the oversight of the TEC HV, LV and gas systems: the PHENIX shift crew
and the TEC experts.

The first level of responsibility resides with the PHENIX Shift Crew.
During any period when the TEC has flammable gas flowing or HV on, there
will be a minimum of two people on continuous shift in the PHENIX
counting house. Once data taking has begun the number of people on shift
at PHENIX increases to four. The second level of responsibility resides
with the TEC Gas, HV and LVexperts. The TEC experts will be on-call to
respond to any alarm or unusual occurrence detected by the PHENIX shift
crew. A record of the performance of the TEC gas system will be
maintained and monitored by the TEC experts.

During watch shifts or data taking, it will be the responsibility of the
PHENIX Shift Crew to:

1.  *monitor the status and alarms for the gas and HV system.*

2.  *In the event of an alarm or unusual occurrence, contact person
    expert from the Expert Call List given in Appendix A.*

The second level of responsibility is the TEC experts. It is the
responsibility of the TEC Gas experts to:

3.  *maintain the TEC Gas System in a safe operating condition. This
    includes:*

    1.  changing gas cylinders and dewars when required,

    2.  setting, adjusting, and checking the gas mixture, flow rates and
        pressures.

    3.  checking the certification of the operating gas, (see details in
        Precautions, Section 4)

    4.  posting any special instructions or notifications as required,
        and

    5.  carrying out any emergency actions, as prescribed in the
        Procedures section of this document.

4.  *maintain the TEC HV Systems in a safe operating condition. This
    includes*

    1.  verifying the readiness of the chamber for HV,

    2.  setting, adjusting and maintaining the TEC HV settings

    3.  turning on the HV according to the operating procedures
        described below,

    4.  posting any special instructions or notifications as required,
        and

    5.  carrying out any emergency actions, as prescribed in the
        Procedures section of this document.

5.  *maintain the TEC LV Systems in a safe operating condition. This
    includes:*

    1.  verifying the readiness of the TEC electronics for LV,

    2.  setting, adjusting and maintaining the TEC LV settings

    3.  posting any special instructions or notifications as required,
        and

    4.  carrying out any emergency actions, as prescribed in the
        Procedures section of this document.

## Prerequisites

The TEC Gas, HV and LVexperts shall have read or have training in the
following areas:

1.  PHENIX Local Emergency Plan, RHIC-OPM 3.16,

2.  BNL Compressed Gas Safety Training Course,

3.  BNL Electrical Safety I,

4.  RHIC/PHENIX access training.

5.  BNL Hazcom

6.  BNL General Employee Training

## Precautions

The safety of personnel is of primary importance. The TEC experts shall
take great care to ensure that the TEC Gas, High Voltage and Low Voltage
Systems will be operated in a way that does not place personnel or
equipment at risk of physical harm.

1.  *Gas, HV, and LV System Precautions:*

    1.  All gas cylinder storage is on the PHENIX Gas pad located just
        south and east of Building 1008 F, the PHENIX Gas Mixing Hut.
        All gas cylinders and dewars are to be changed by designated
        PHENIX personnel with current BNL Compressed Gas Safety
        Training.

    2.  All valves and controls associated with the TEC Gas system are
        to be operated ONLY by designated TEC gas system experts with
        current training.

    3.  Primary care should be given to monitoring the internal pressure
        of the TEC throughout the duration of the start-up procedure,
        especially when adjusting flow rates. Over-pressurization of the
        TEC (above 7.0 mm WC) can result in structural damage to the
        detector.

    4.  The total energy stored in the TEC with High Voltage on is low,
        \~ 10 mJoules, adjusting the voltage is not dangerous from a
        personal safety stand point. Additionally, all HV points are
        covered on the TEC such that one would have to remove covering
        material in order to feel any shock. However, there is
        significant risk of damaging the equipment, the TEC, without
        proper operation of the HV.

    5.  **Before any HV can be turned on, sufficient P-10 gas must have
        flowed through each of the detectors for 4 volume exchanges. The
        total gas volume of all TEC planes on the East carriage is 6000
        liters. The TEC HV is to be turned on only by a TEC HV expert
        with current training. An exception is listed in 4.1.6**.

    6.  All HV controls associated with the TEC HV system are to be
        operated ONLY by designated TEC HV experts or by the PHENIX
        shift leader following specific instructions from TEC experts.

    7.  Any reconfiguration or adjustment to the TEC Gas or HV system in
        the PHENIX IR is to be performed ONLY by TEC Gas and HV experts
        with current training.

    8.  Any reconfiguration of the TEC LV beyond turning the power
        on/off is to be performed by TEC LV experts or people
        specifically designated for the job.

## Emergency Procedures 

1.  *In the event of a fire or emergency in Building 1008, members of
    the PHENIX Shift Crew shall (in order of priority)*

    1.  Follow emergency procedures described in C-A OPM 3.16 for the
        PHENIX area.

    2.  All TEC HV should be turned -off by the PHENIX shift crew or TEC
        experts..

    3.  Confirm that the TEC Gas System is in safe/purge mode. The shift
        leader or TEC Gas system expert can confirm that the
        alarm/safety system has functioned properly by going to the
        PHENIX Gas Mixing Hut 1008F, and observing that the AC power to
        the TEC Gas system is off , the argon flow meter shows flow and
        that the CH4 flow meter no-flow. This action should be taken
        once it has been determined that no hazard exists in 1008F.

2.  *In the* *event that a TEC gas line ruptures, the Shift Leader or
    TEC Gas System expert shall:*

    1.  Turn off all gas flowing to the TEC at either the TEC Gas system
        computer control in the Gas Mixing Hut, the gas distribution
        values in the Mixing Hut or the cylinders and dewars on the
        PHENIX gas pad.

    2.  Turn off the power to all TEC high voltage (HV).

    3.  Contact a TEC Gas expert . ( See Appendix A).

## Standard Operating Procedures

There are three elements to these Operating Procedures. The first
element covers running gas to the chambers. The second covers the high
voltage system for the chambers. The third element covers TEC LV
controls. These Procedures shall be carried out by TEC Gas, HV and LV
experts only.

The procedures for operating the TEC Gas, HV and LV systems are
described in general terms in this OPM. A more detailed description of
the TEC Gas system and its operation can be found in the *PHENIX Central
Tracking* *Gas System Design and Specification Manual (March 2000)*,
especially see the section on the Alarm System in this document. The TEC
Gas system experts will have familiarized themselves with this document.
A more detailed description of the PHENIX HV system and its operation
can be found in *PHENIX HV Control Manual 2.5.3.14-08*

The Gas system for the TEC is composed of a number of components.

1.  Gas source of cylinders and dewars located on the PHENIX Gas Pad.

2.  Gas distribution manifolds located in the PHENIX Mixing Hut 1008F

3.  TEC Gas rack located in the Gas room in 1008F

4.  TEC Gas Electronics Rack located in the Electronics room of 1008F

5.  TEC carriage gas rack located underneath the East carriage in the
    PHENIX IR.

6.  TEC sector-flowmeters and flow direction indicators mounted on the
    TEC sectors in the PHENIX East carriage.

    When the PHENIX IR is closed the status of the TEC Gas system can be
    monitored in a number of places.

```{=html}
<!-- -->
```
1.  TEC Gas Control computer located in the electronics room of 1008F
    shows the status of all electronically readout flow meters, flow
    direction indicators, pressure transmitters/indicators, solenoid
    valves and temperature transmitters.

2.  TEC Gas Control rack located in the Gas room of 1008F shows status
    of all manually controlled flow meters and pressure gauges.

3.  PCs located in PHENIX Counting House allows monitoring of TEC Gas
    system logging file created by the TEC Gas Control computer.

4.  TV monitor located in PHENIX Counting House allows one to use
    cameras in IR to view status of flow meters and pressure gauges
    located in TEC carriage gas rack underneath the East carriage.

For details of the gas system, please refer to the TEC Gas System
diagram located in Attachment B and the *PHENIX Central Tracking Gas
System Design and Specification* *Manual, March 2000*. The labels of
valves and meters in the operation instructions below refer to parts
identified in the figures in Attachment B.

**Note: All the flow rate settings specified in the procedures below are
nominal and can be adjusted by the TEC gas system experts as in
accordance with the requirements of the TEC detector or gas system.**

1.  *Gas System Procedures* The Procedures describe starting gas flowing
    to the TEC after a long shutdown. They assume no gas is currently
    flowing, no flow meters are adjusted and the PHENIX IR is open. If
    the PHENIX IR is closed it is necessary that the TEC carriage rack
    and sector flow meters have been previously adjusted prior to any
    gas flow. Check that PP-2.5.3.4-09 *Check-off List for Ending Access
    to the PHENIX IR* has been completed. If no gas has been flowing in
    the TEC for 24 hours one must start flowing inert gas first.

    8.  Turn off the AC power for Power supplies and Gas Rack

6.  *HV System Procedures: Turning on HV:*

    **If the HV is being turned on the first time, verify by checking
    with TEC Gas experts that operating gas has been flowing to the TEC
    for a minimum of 4 volume turnovers . The TEC can be damaged if the
    HV is turned on without the chambers containing the proper gas
    mixture.**

    Check that the appropriate current limits are in place for the power
    supply. These limits are given in Attachment C. The TEC HV experts
    shall maintain a HV logbook where the operating parameters of the HV
    settings are recorded. This shall include the current limits, target
    voltages, ramp rates, operating voltages and currents, and trip
    tolerances.

    1.  Go to the HV control computer in the PHENIX Counting House.

    2.  Check that the current limits, ramp rates and trip tolerances
        are set in accordance with the values in the TEC HV logbook.

    3.  Check that the target voltage for each HV output line is
        appropriate (50 volts). The first stage of bringing on the HV
        shall be a single increment in the ramp up. This is because the
        current trips are disabled during ramping, and in order to
        locate a short in the system, it is necessary to halt the
        ramping and check the current at the earliest possible stage.

    4.  Check that the ramp up rate for each HV supply is appropriate
        (50 volts per step).

    5.  Ramp up the HV to 50V to test for electrical shorts.

    6.  If HV current stays low, \< 1 microamp, set initial voltages on
        computer control.

    7.  Begin ramping Drift Window and Anode HV. Set Drift Window HV to
        logbook setting. Set Anode Voltages to 200V below logbook
        settings. Leave WC2 and BW off for now.

    8.  Inspect current draw on HV computer screen. If any channel has 5
        microamps current draw after 5 minutes reduce the HV setting on
        that channel by 100V and wait for the current draw to drop**.
        Any channels exempted from the 5 microamp limit will be
        identified by the TEC HV experts and noted in the TEC HV
        logbook**.

    9.  Leave the HV at these settings for 1 hour.

    10. If current draw is stable after 1 hour increase the anode
        voltage by 50 volts and repeat steps 6.6.8, 6.6.9 until reaching
        the HV values noted in the log book.

    11. If at any point during this procedure there is a HV trip
        determine the reason for the trip and return to step 6.6.3 for
        that channel. It may be necessary to reduce all 4 bias voltages
        on a particular TEC chamber prior to restarting the HV ramp-up
        procedure on that chamber.

    12. If DW and Anode voltages are set to logbook values and the
        current draw, especially on the anode wire , has been stable for
        a minimum of 1 hour begin setting the Wire Cathode 2 (WC2) and
        Back Window (BW) voltages to the logbook settings in 50V
        increments in a manner similar to steps 6.6.8 -- 6.6.11

    13. If HV trips occur during normal TEC operation determine the
        cause of the trip and restore the tripped channel to 50V below
        its most recent operating value. Wait a sufficient amount of
        time to allow the current to stabilize. Restore the channel to
        its logbook value. If the channel continues to trip at the
        logbook value reduce that channels HV operation setting by 50V
        and make a note in the TEC HV logbook.

    14. Once all TEC HV channels have been set to the appropriate TEC HV
        logbook values or their new modified values, monitor all
        channels for the operating current and HV trips. Keep a record
        of all TEC HV actions, especially unusual occurrences in the TEC
        HV logbook

    15. The TEC is ready for HV operation.

7.  *HV System Procedures: Turning off High Voltage to a chamber:*

    1.  Begin ramping down the HV.

    2.  Verify by the read back that the HV is off the system.

    3.  In the event of irregularities, call a TEC HV expert.

8.  *LV System Procedures: Turning on Low Voltage:*

    1.  Go to LV control computer in the PHENIX Counting House

    2.  Go to PHENIX Rack Control and Monitor page and turn on the
        appropriate TEC racks.

    3.  Verify that the AC is on to the LV crate.

    4.  Turn on one rack of LV supplies at a time powering the G-P and F
        supplies in the proper sequence as specified by the TEC
        experts**. The sequence the TEC LV supplies are turned on is
        very important for the proper operation of the TEC
        electronics**.

    5.  Verify that the LV supplies have come on by monitoring their
        status on the TEC LV control page. If the LV will not come on in
        some particular channel call a TEC expert.

9.  *LV System Procedures: Turning off Low Voltage:*

    1.  Click on the appropriate button on the TEC LV computer page to
        turn LV power off to the channels required.

    2.  Verify that the power has turned off by monitoring its status on
        the TEC LV computer page.
