TRD Sector 8 SM Commissioning Status and Plan

TRD Sector 8 SM CommissioningStatus and Plan

• Ken Oyama
• Mar. 30, 2007
• TRD Status Meeting _at_ Bonn

2
First Commissioning Try Till 2 Days Ago

• tested Items so far
• LV Services (David, Kai, Benjamin, Christian).
• DCS network infrastructure (David, Tom).
• FeeServer, ControlEngine, DB (Kai, David, Tom,
  Uwe).
• Control with PVSS etc (Georgios, Jorge, Kai,
  Michael, Jens).
• Cooling (Ana).
• some temporary stuff
• Linux worker node with our
• diagnostics tools used at KIP.
• .bin ? .root ? digits conversion
• tools (Minjung).
• Software Interlock running on
• PCU (Kai, David, Tom).

Working LV ans Successful in Configuration
PVSS panels by Georgios and Michael were used for
operation.

Results of the Last Try

• Services prepared by David et.al. work very well.
• Readout chamber status and operation
• Good, no significant changes from SXL2 tests,
• Power up successful with normal current. No
  shorts.
• Configuration was ok with script based tools.
• Dummy configuration sent to the chambers with
  full chain.
• Noise scanned (13 events) using DCS board readout
• next slides.
• Cooling performance is good (23 K rise).
• Dead HC (S2L0) is still dead unfortunately.

More Precise Performance Study Started
Plots by Minjung
RMS noise nominal 1.25 ADC counts 1300
electrons except for bad MCMs

For Further Commissioning

• Final goal
• Take cosmic data with final DCS infrastructure
  and DAQ and trigger infrastructure directly
  related to TRD.
• Gas will be available middle of Apr. (Chilo).
• H.V. distribution box will be available end of
  May (Maria).
• DCS Infrastructure will be debugged a lot in
  Apr..
• Performance tests will be done end of Apr. (Kai
  et.al.).
• New FSM based DCS system will be installed end of
  Apr. (Jorge).
• Optical fibers ready (David). DAQ ready.
• (5 DDL?) GTU will be ready end of Apr. (Volker
  et.al.).
• Pre-trigger (partially available, discussed
  later).
• Software, Analysis Tools (MOOD Benjamin,
  Minjung).

8
Commissioning with CTP and Trigger Detectors

• LTUTTCex are there (we can borrow).
• ACORDE is ready to provide trigger to the CTP.
• Assuming 50 m cable length from ACORDE to CTP,
  pre-trigger latency is 1 us (0 pre-samples).
  With direct connection, 2 pre-samples possible.
• Cosmic rate in SM08 0.5 Hz. It is much lower
  with ACORDE (studied by Minjung). Preparation of
  cosmic paddles in the magnet is proposed.
• Not allowed to operate during daytime. We run
  overnight.
• T0/V0 will be installed on Apr. 1. and will have
  services in end of Apr..

9
Commissioning with Pre-Trigger System

• FEB for C side in production (90 produced).
  Tests just started (Massimiliano, Robert).
• 5x FEB C Installation planned 10, Apr..
• Pre-amplifiers for T0/V0 arrived (have wrong
  components).
• CB-TOF hardware ready. Being debugged (Rainer).
• CB-TOF will be used partially (DCS board TTCex)
  in Apr.. commissioning.

10
Needs Many More Preparation for Long Run

• Chairs and tables
• Quick plug play cosmic system
• Easy use hacking PCs
• Tools
• Air sprays (inside Magnet is really dirty)
• SMEC Covers
• Housing
• Cars

After taking 1st event Wednesday 28, Mar. 500 am
David, Georgios, Kai, Minjung, Ken
