TRT Barrel Transferred

• TRT Barrel now in ID trolley– Worked well– Nice system to verify load balance during movement


Tooling for insertion

• ISSS assembled and covers implemented for service protection

– See Richard’s talk

• Cantilever stand in place and adjusted. • ID trolley and rail system tested with dummy

loads– Found ok and proceeded with TRT transfer

• SCT cradle lifting tool– See Eric’s talk– Ready in SR and tests with dummy load

(750kg) completed

• Service supports on ID trolley– Production ongoing in Gva workshop– Main supports in SR1– Will test first Service supports on ID trolley this

week

• Dry-fits this week– ISSS on ID trolley– ISSS on SCT cradle done

• Tools ready for insertion


Outstanding work on TRT until insertion(Anatoli)

• Regarding tests:– Add cable trays – Add test harnesses to

barrel– Install disassembled &

repaired manifolds

• Add scintillators– To service support in

TA + under trolley– Check possibility to

mount 1 scint. Under platform

– Anatoli & Didier

Read out Cables

Pipes

Counters will be positionedon the Test area structure


Checks before insertion

• ISSS:– Mount ISSS on ID trolley for checks

• Scintillator– Need to define precise location of scintillator now– Mounting of top scintillator on service support in TA– Bottom scintillator below platform?

• TRT Cable support– Needs to be designed to fit in ID Trolley

• SCT cable support– Need to mount support for TPP on ID trolley before

insertion (start this week)


Work on TRT Barrel

• General plan regarding TRT manifolds– See Richard’s talk

• TRT manifolds & Combined testing:– Start with top sector + repaired manifold– New manifolds will be manufactured & installed in breaks of combined tests– Detector will be off during installation of manifold for safety– 2nd sector will be cables when new manifolds are installed there.– Replace old manifold at end of tests (requires to stop tests 1 ws earlier)

• Additional TRT work until insertion– Installation of fuse boxes (largest task)– Temperature sensor mounting (ongoing by Crakow group), need 1 more wk to finish– Phase-tests on TRT (t0 determination) 1-12 Dec


Present work on SCT(Lewis)

• Done:Cooling Reference Disk InstalledInner Support Rings InstalledC-side still tobe done

Front bulkhead and cover panels

trial fit

41/44 Loops Succesfully tested with a leak rateLeak Rate <5x10-10 mbar.l/s (with Helium)

3 loops show a large leak ~10-5 mbar.l/s with Helium. Leak position known to be at solder joint at exhaust.see Richard’s talk


SCT Cooling investigation

• This is the main pending item towards final OK for insertion on 12 Dec– Update on Friday

• Precise location has been demonstrated by swabbing alcohol over the joint. >> This seems to have wicked into the leak and temporarily sealed it. 2 of the 3 leaks returned after a few minutes. The other is still leak tight...

• The cause of the leaks are unknown - under investigation

• We plan to examine the barrel cooling loops using endoscope.

• We could examine the barrel sector Barrel 6 at RAL


Outstanding work on SCT(Lewis)

• Work on hold pending curing cooling problem– Install Cooling Reference Disk to the –Z end of barrel (0.5 day)

– Install front bulkheads and cover panels (1 day)

– Leak testing of Thermal Enclosure (TE), and additional sealing(1 day)

– Install ISSS to barrel cradle (1 day)

– Move services into ISSS (5 days)

– Dismount service support frame (0.5 day)

– Prepare cradle for travel (0.5 day)

Total 9.5 days

• Parallel Tasks possible– Installation of environmental gas pipes and flow test (1 day)

• Equipment and parts to be set up this week

– Inspection and testing of Grounding and Shielding (5 days)• Ned Spencer to undertake this week

– Final preparation of DCS cabling (5 days)• Underway this week

Total 11 days

(Potentially services can be installed into the ISSS at +Z in parallel with the cooling investigation)


Environmental control during Combined Tests

• Supply– Dry air supply as used during the single barrel tests– 2 desiccant stages. We will connect to the output of the 2nd stage (local in test area)

• Main goal– Dry-air with dew point below 0C for warm operation (approx 10C on pipes)– No under pressure and maximum 4mbar over pressure.

• Must not damage enclosure

• Installation– Input pressure dropped through long inlet pipe

• 150m ID 4mm pipe supplied with 0 to 8 bar inlet pressure at max flow of 1500 l/hr

– Use 4 output exhaust lines• Limit risk in case one pipe is blocked

• Pipe length/diameter designed to create output backpressure of 0.5mbar without the need of bubbler.

• End of exhaust pipe is in “clean air” environment in case of accidental under pressure

• Material ordered and (mostly) delivered

DAQ work

• See talks from yesterday’s ID int meeting by Trevor, Bruce, Alan, Dave, Peter– http://agenda.cern.ch/ fullAgenda.php?ida=a057592

• ROD DSP work– Error decoding & several improvements/fixes implemented– Trigger-time out bug still under investigration– Continous functionality on-going using TB sector in TA– DSP code nearly ready for cosmics running

• ROS readout /Slink tests– All hardware (12 ROD/BOC) in place and tested– 3 Filar installed in ROS PC and running tested

• 8 fibres on order

– ROS and Run Control running together with TRT (Mike)– Standalone tests for SLink-Filar implemented

• Successfully taken test data from the CTB testbeam modulebox using multiple FILARs in a single ROS







DCS / FSM / interlock work

• See talks from yesterday’s ID int meeting by Ewa, Bilge, Bjarte, Bettina– http://agenda.cern.ch/fullAgenda.php?ida=a057592

• First FSM for combined ID tests in SR1 installed– See Ewa’s talk– FSM hierarchy prepared only for components which are used for tests– develop FSM only for monitoring purposes– NO COMMAND will be sent by the FSM, – States and status will be propagated in the hierarchy– Tests of SCT and TRT tests in SR are going on now

• CoolDB– See Bilge’s talk– Interface prepared to save run summary and configuration + some calibration data

• DCS data handling– Tests with CoolDB ongoing– Not clear that performance of PVSS->Oracle ok for storing DCS data ok for combined tests– Standard PVSS archiving as done during single barrel tests always an option

• Not very safe and overhead in reading back data• Meeting end of the week w/ experts to define

• Interlock system– See Bettina’s talk– Will use final DCS patch panels (required new cables, done now)– New BBIM crate installed, BBIM backplanes needed mods (on-going)– Most hardware now in place and tested for Combined test







Event display

• Display detector specific information

• Exists for TRT, needed for SCT• Bettina will take charge to implement SCT specific part


Configuration for Combined Test

View from outside towards Side A • Cabling:

– Will not get new manifold for both sectors by Dec

– Install old manifold in top sector (stack 7 & 8) and cable

• Cable top stack first• Cable bottom when

new manifolds are ready

• Initial running with TOP sector!


Cabling & startup session in TA

• Breakdown of cabling session– Made for 2 sectors initially (optimistic)

• Startup for Combined Test (26-27/1/06 )– Run TE dry (1-2 days?)– Need ~ 2-3 days with detector occassionally on to correct the (expected) cabling errors

before serious testing can start

• Start Combined Tests earliest in week 30/1 - 3/2
