Title: Sourcing and Source Driver Status
1Sourcing and Source Driver Status
- Ianos Schmidt
- CMS Week Feb.08
2Outline
- Air Drivers HE
- Air drivers HB
- Air system
- HF Source tube installation
- Electric drivers
- USC cabling
- Control electronics
- Software
- Miscellaneous issues
3HE drivers
- HE
- Drivers setup, tested and loaded with dummy
wires. - Drivers installed and tested for proper
operation within the HE. -
- HE specific to do
- Install Geiger counter in nearside driver.
- HE-
- Drivers at CERN and setup complete. Now under
test. - Expect to be ready for installation in 1 week.
- HE- specific to do
- Install drivers, and related air pipes. Expected
time window w/I 2 weeks. - Connect control cable from cable chain.
- To do (Both endcaps)
- Improve blocking of unused indexes
- Virgil provided parts for blocking tubes. To be
installed when access available. - Reinforce tubes at indexer bars
4HB Air drivers
- Drivers at CERN, Setup, tested and ready for
installation. - Problem with uneven driver mounting brackets .
Solution using spherical washers proposed.
Increases height of drivers by 6mm, OK by Sasha
Sirkov. - Dummy driver base plate produced so that bracket
installation can now be tested. - Driver installation delayed because of
incompatibility of mounted drivers and the
cabling infrastructure presently installed in the
cryostat - The dummy driver base plate can also be used to
investigate the possibility of eliminating this
incompatibility.
5Air system
DONE
Filter 20u
Lock out valves
- YE1,YB0-near Panels completed and installed
- YB0-far,YE-1Panels Prepared, waiting for
delivery of valves. (expected Feb.20).
Completion imminent.
DONE
- Need to understand USC Installation. Who does
what? - Connection of hoses to USC needs to be completed.
6HF source system.
- HF nearside tubes installed in their final
configuration, and attachment to the driver
indexer nearly complete. - Remaining tubes installed in the shielding and
connected to wedges. Require inspection, rework
where necessary, and final tie down before
connection to indexers.
288 tubes need to be Connected to each indexer
HF- trial installation. Needs some re-work
7Electric Driver (Status from Iowa)
- Four drivers for HF ready to ship except for
larger lead garages. - Decide on Monday weather to ship with original
pigs or wait for larger ones. - All parts (except lead) for electric drivers have
been produced. Assembly of remaining temporary
drivers will start after shipping of HF drivers.
Note Due to the use of stronger sources it had
been established that the original lead garages
were insufficient. As lead is not a popular
material to work with ,particularly at CERN, and
because technical resources are limited at CERN,
I requested to have Iowa produce the designs and
evaluate the production of the larger garages as
part of the driver upgrade project.
8USC cabling
-
- Termination of electric driver cables nearly
complete (just HF on detector left). - Connectors for Air driver cables were needed.
Connectors provided this week. Again completion
is imminent.
9Control electronics
- Power supply box delivered to CERN (S.Linn).
- Board layout done.
- Gerber files being checked.
- Parts lists nearly final,
- Front panel layout complete
- To Do
- Layout backplane boards
- BU needs schematics from me.
- Produce prototype boards.
- Assemble Crates
- Build interlock box.
- Need to resolved interconnection of interlock to
zone safety infrastructure (switches, locks,
lights). - Note We have prototype boards at CERN which
will us to commission drivers.
10Software
Eliminate Windows based server!
- Rewrite of server started.
- Migrated to MS C
- Allows dynamic creation/destruction and
configuration of controller instances. - More compatible with DAQ configuration paradigm
and no longer requires local configuration files. - -Configuration to be from DB via XDAQ.
- Controller code revised when new boards
available. - XDAQ Software started.
- Still lots of work for me to do here.
Control of drivers will now be directly from
XDAQ.
11Miscellaneous issues
- Need to perform dummy scans of all the PSD tubes
to establish a database of as installed tube
lengths. Will take some time/effot. - Need storage/transport boxes (23432 14
min.) - 3 provisional boxes made by me but currently
contain sources. - Plan to use HO RBX boxes. Design provide for
production of lead storage pigs. Production can
start whenever possible. - Need to procure some hardware for final assembly.
- Zone interlocks, access control, safety and
procedures - RP, CMS GLIMOS (Christoph) and Pawel have
reviewed the risks specific to our installation,
and have established the general access control
strategy. - LHC people will specify the safety infrastructure
needed (HCAL does not do safety infrastructure). - Need to establish the interface to the source
driver interlock. Christoph referred us to the
appropriate LHC contact person. - Procedures for the use of sources are under
revision to fully address the requirements and
specific implementation in the UXC environment
(Pawel).
