Presentation Transcript

Tracking: 

Tracking Organisation: A deputy will be appointed after consultation of all the 6 labs. involved in the tracking Background: Very recent calculations by A. Morsch for B=0.4 T in L3 show an increase of  background, essentially in Station 2 B=0.5 T ?

Background station 1: 

Background station 1

Background station 2: 

Background station 2

Stations 1 and 2: 

Stations 1 and 2 First quadrant Station 1 currently in construction, should be ready by mid-May, tested on beam first week of July. If OK, Mass production start by beginning of October 02 (no need of tendering) (cf J. Peyré’s talk) Between 3 and 4 months construction per quadrant=> Completion by March 2005

Stations1 and 2: 

Stations1 and 2 Chamber 0 Station 2 currently in construction, will be delayed by approximately six months due to granularity changes and to derive benefit from the Station 1 tests (in particular electronics back-plane) (cf Pratap’s talk) PRR for the two first stations should be held by June Between 3 and 4 months construction per quadrant=>completion by March 2005

Stations 3, 4 and 5: 

Stations 3, 4 and 5 Details in Manoel’s talk First full size slat (2400 mm) in-beam tested in October with good results. Some technological details to improve (quality control)(Eric, Christian) PRR for stations 3,4 and 5 held at Nantes on 10 and 11 December. General comments are satisfactory but some questions from the referees. Work is going on for giving answers

Stations 3, 4 and 5: 

Stations 3, 4 and 5 Design and mechanical tolerances on frames under investigation. Need of the final GMS solution otherwise conservative design (Alberto) Market survey for sandwiches, spacers, PCBs and frames completed (Corrado on the PCBs) Tendering for the carbon sandwiches in the final phase

Stations 3, 4 and 5: 

Stations 3, 4 and 5 Tooling construction or purchase is going on in the different labs Ageing measurements foreseen at GIF Need of training for slat construction in each lab Head of production by end of 2002 Construction completion by May 2005 Up to now cost to completion approximately as foreseen (frames ?)

Integration: 

Integration Seems OK for station 1 and 2 but very tight (J. Peyré) Station 3 more or less OK, also very tight Stations 4 and 5 seem OK (F. Orsini’s talk) Cooling (A. Tournaire’s talk) with a common solution for the 5 stations (system with 5000 m3/h fresh air) New simulation calculations undertaken at Orsay and Saclay Measurements performed on the chip temperature

Electronics: 

Electronics All details given by: Pierre on the general architecture and status Pratap for the MANAS performances and status Gianluca for the last information on MARC C. Oziol for the architecture and status of CROCUS Just to summarize, R&D in final phase with the debugging PRR expected by autumn 2002 together with the market survey Beginning of mass production by mid-2003

AOB: 

AOB HV solution in discussion (CAEN 1527.vs.Gatchina home made solution) DCS difficult to organise (help of Calcutta ?) Problem with russian money (360 kChF for the tooling) A solution for the GMS system is rapidly required Discussion on the updating of the planning is necessary

Summary: 

Summary End of the R&D phase and beginning of construction for the detectors in 2002 A few uncertainties remain on the electronics, should be solved for fall 2002 Work still to be done on cooling Up to now, no big concerns on the budget The tracking system seems to be in quite a good shape

Detector Control System: 

Detector Control System Questionnaire on DCS requirements filled and sent in January. Devices to control: HV: Reading of HV values (1V precision) and currents (10 nA precision) Dynamic adjustment during running and a second set of parameters between 448 and 700 channels (depending on the cost) CAEN SY1527 with A1833B or Gatchina home made supplies LV: 3x96 values to control

Detector Control System: 

Detector Control System Low Voltage 3 voltage values (+2.5 V, -2.5 V and +3.3 V) with max. Currents ~ 25 A Reading voltage (1 mV precision) currents (10 mA precision) WIENER PL 500 Actually 96 (x3) channels but maybe more for safety reasons (Slat PRR conclusions) Necessity to cut the 3 LV together for each channel

Detector Control System: 

Detector Control System Gas system In charge of the working gas group Cooling Temperature measurements of the incoming and out coming air Air flow control (system On/Off, flow) Water cooling circuit (water temperature, pressure, flow) Temperature measurements on the detectors Global Monitoring System

Detector Control System: 

Detector Control System Next future Beginning of a collaboration with SINP The user requirements has to be written Need of an engineer in the occidental labs
