**Endcap C Daily Status**

May 16, 2006: Endcap C arrives at CERN. Visual inspection OK. Pictures
are in \"EndcapCArrivalCERN\" in the usual spot, including subfolders of
pictures taken at CERN. This daily section will be \"archived\" tomorrow
in Word document and future entries will describe Endcap A.
Congratulations to all!

May 15, 2006: Endcap C flies away at 0745. Smooth operation. Few
pictures in \"BonVoyageEndcapC\" at the usual link.

May 12, 2006: Final organization for flying on May 15.

May 11, 2006: Packing in shipping box completed. Pictures of this in
\"ShippingBoxandBuggy\".

May 10, 2006: Integration of endcap C is complete and it is ready to put
into shipping box tomorrow. Pictures are in folder
\"EndcapCFinalIntegration\" at the link at top.

May 9, 2006: LBL photo services pictures. Tube constraints added. Trial
fit of rest of plastic holder. Regular pictures in the
\"EndcapCFinalIntegration\" folder at the usual link top of page. Foam
for inside shipping box arrives. Trial fit of box+extra foam in car.

May 8, 2006: Continuity testing completed. OK. Work on tube clamps and
plate. Work on shipping box continues.

May 5, 2006: Leak check of 3 disks in frame complete and OK. However,
cork used in leak testing fell and ended up on module on sector 9048 in
disk 1C. Pictures in folder \"LeakCheckEndcapC\" in link at top of page,
including cork. Cork removed(easy). Continuity testing done, no apparent
damage. Continuity testing of all modules in progress(see pictures in
\"ContinuityTesting\" folder). Protective side panels added. Started
machining tube holder parts. Additional work on shipping box(ground off
a bit on inside bottom to get more clearance and added labels) and
modified baby carriage. Pictures of shipping box and buggy are in folder
\"ShippingBoxandBuggy\".

May 4, 2006: Disk 3C was integrated into frame. There was an
interference between the Disk 2 exhaust and the strain relief clamps on
Disk 3C. Material on the clamps was removed. Remaining clearance between
Disk 2 pipes and Disk 3 sector pipes is very small(0 to sub mm) but we
decide to live with it. Pictures in folder at link at top.

May 3, 2006: Disk 2C was integrated into frame. Low resolution pictures
at link at top.

May 2, 2006: Disk 1C was integrated into the endcap frame. Pictures are
in a folder(Disk1CIntegration) at the link at the start of this page.
Note there are some very high resolution shots from LBL photo
services(and currently very big files).

May 1, 2006: Final capillary attached to 3C. Leak check OK. Glue(9396)
added to exhaust strain reliefs on 1C, 2C, 3C. Bolt up and fit up of
plastic holder parts underway. Work on shipping parts continues. Plan to
start 1C integration tomorrow.

April 28, 2006: Initial fit-up of plastic holder pieces and aluminum
temporary endplate completed. Final capilary for 3C leak check OK after
pressure cycle. Thermal cycle over weekend.

April 27, 2006: Plastic machining/gluing continues. More work on
shipping box, foam and shock logging. Started modifying baby buggy for
moving box in airport. Photo documentation of 1C, 2C and 3C by LBL photo
services.

April 26, 2006: Three capillaries added to 3C. Pass leak check. Plastic
machining continues. Capillary glued yesterday passes leak check.
Pressure cycle Friday, thermal cycle over weekend, test and install
Monday. Paperwork, shipping procedures advancing.

April 25, 2006: Capillaries added to 2C. Pass leak check. Had to adjust
one exhaust location. OK also. Nuts tacked on 2C. Three other
capillaries pressured cycled and pass leak check. Ready to put on 3C
tomorrow. Progress on plastic holder parts towards assembly planned for
Friday. Another capillary glued to replace one with backward nut but
wont be ready until May 1.

April 24, 2006: Added Endcap C plan and status link above. Nuts on 1C
tacked. Three capillaries for 2C pass leak checks after pressure cycle.
4th had a nut on backwards! QA failure.

April 21, 2006: Capillaries attached to 1C and leak check OK.
Capillaries for 2C and 3C will start thermal cycle Saturday and Sunday,
respectively.

April 20, 2006: All disks have clamps replaced. Capillaries for 1C pass
final test(after thermal cycle). Plan to attach them tomorrow.
Capillaries for 2C and 3C are curing. Decided to make temporary endplate
for C endcap, which means attaching clips to real endplate is off path
now. Target date to begin integration of disks is May 1. Two visits
yesterday to SFO, including trial of carrying box on plane in seat.
Looks like hand carry can work. Target date for flight is May 15.

April 19, 2006; All 3 C-side disks have clamps replaced. Working on
first A-side this afternoon. 1C capillaries in thermal cycle, will be
done tomorrow afternoon. Plan to leak check and if OK attach Friday.
Capillaries for 2C glued today. Will cure until Saturday and start
thermal cycle then(reversal of test sequence). Stay clear regions
identified but have decided to make temporary end plate and leave real
one for attachment after system test on endcap C. Maurice and Gil
visited SFO and talked to Continental and TSA. Encouraging enough that
will go back tonight and hopefully trial fit box on 757 to make sure it
works.

April 18, 2006: Room temperature cure looks good. 4 production
capillaries OK after pressure cycle, thermal cycle starts today. Thick
Type 0 clamps replaced with skinny ones on two rings. SLA clips for Type
0 on endplate look good, need to clarify stay-clear regions.

April 17, 2006: Capillary testing is summarized at link above. So far it
looks like all OK with room temperature cure but will start testing 4
production capillaries tomorrow after 3 day cure. Pressure cycle
tomorrow, then temperature cycle for 2 days. Production of SLA clamps
for Type 0 underway and will begin replacement tomorrow. If capillaries
are OK, then roughly expect to begin integration of completed disks(with
capillaries, new clamps, tacked nuts, etc) on May 1.

April 14, 2006: We need more capillary samples. Decision to proceed with
four tuned capillaries, glued as per procedure and let them cure over
weekend and at least Monday AM. If OK, then 1st 4 production
capillaries. This would give us 8 samples more to test. Together with
previous, 11 samples made by Mario with room temperature cure. Two would
be tested April 17 AM, pressured cycled and tested. One after thermal
cycle(already pressure cycled) is OK. Will also glue up samples using Cu
plug soldered to capillary. Type 0 thin clamps look OK so production can
start by April 17. Plastic machining proceeding but delayed by having to
make capillaries. See link above for capillary status summary.

April 13, 2006: One more iteration of the Type 0 clamps is needed and is
underway for tomorrow. Type 0 clip samples OK, given to make model for
SLA parts. Status of capillaries is summarized in the table linked
above.

April 12, 2006: 6 of 10 fittings on the 5 capillaries can be removed
with just fingers. Very poor adhesion. We cured these at 150F for one
hour after an overnight room temperature cure(to speed up). Is this the
problem? Not clear. We did not do this in the qualification. Test sample
passed all tests(including 50 cycles at 20 bar). It cured at room
temperature. Started temperature cycling this sample. Cooked one fitting
glued by Jon some weeks ago to 150F. It also fine after 50 20 bar
cycles. Decide to make up 4 more samples, cure overnight. Two will be
cooked at 150F tomorrow and 2 leak checked without this. Type 0 clamps
redesigned and two variants submitted. Sample Type 0 clips that have to
be glued on endplate produced.

April 11, 2006: Capillaries with fittings leak, or many fittings. Type 0
clamps not quite correct fit, need small modification.

April 10, 2006: Possible dirt found in 1A joint that leaked. Cleaned. 1A
tubed checked. OK. Put back on. Leak tight. All U-tube and exhaust now
on and leak checked OK. Test capillary glued fitting leaked checked
(improved technique, new person doing the gluing). OK. Five capillaries
glued. Type 0 cable clamps look good but need to countersink holes for
lowest profile. Plastic holder fab continues.

April 7, 2006: Summary of status. U-tubes on all disks, OK. Exahust
tubes on Disk 2 and 3 C and A, OK. Disk 1 exhaust positions were found
last week to be wrong, removed. Disk 1C replaced and OK. Three of 4 on
1A OK, leak in 4th(found late today). In exhaust tube or at joint. To be
investigated. Have developed method to tack nuts against vibration.
Final skinny clamps(we hope) to hold Type 0 are in fab over the weekend.
Design of plastic holder for transportation and holding in system test
is complete. Materials in hand. Fabrication held up by illness of
personnel. Seven capillaries tuned. Fitting gluing started on batch of 5
capillaries for Disk 1C. Transport box arrived. Visit to SF airport
planned to discuss with airline and security. Roughly one month away
from shipping to CERN is guess.

March 27, 2006: U-tubes attached to 3A. Leak check on U-tubes OK but
leak found near other fitting on sector 9009. Investigating. Parts for
plastic holder ordered. No progress on pieces for gluing Type 0 or
fixing nuts on fittings against vibration loosening. Capillary tuning
procedure still proceeding, trying first production sample tomorrow.

March 24, 2006: U-tubes attached to 2A. Leak check OK. U-tubes on 1A
retorqued. No movement. Design of plastic holder continues. Concept for
gluing Type 0 to strain reliefs(last item before insertion) developed.
Development of capillary tuning continues(converging).

March 23, 2006: Disks 1C, 2C and 3C are inspected and have U-tubes and
exhaust tubes attached and leak checked successfully. Disks 1A, 2A and
3A have been inspected. HV bonds on a module on 3A have been repaired
and module tested OK. U-tubes have been attached and leak checked on 1A.
Design of plastic shipment/system test holder parts underway.
