6
TRD Planning Milestones

• planning of sub-projects milestones
• radiator
• readout chamber
• electronics
• gas system
• cooling system
• detector control system

7
Overall Timeline

• driven by overall ALICE installation schedule
• need to finish at least 2-3 supermodules for
  installation below beampipe by August 2005
• rest of installation starts April 2006
• 50-100 issue still open ? repercussions on
  installation scenario

8
Radiator Production

• at current rate of production probably done by
  October

9
Chamber Production

• delay since start of production lt 1 yr
• some slack to catch up
• stacking of supermodules moved from Mar-04-gt
  Jan-05

10
PASA Production

• Delay compared to official schedule 1yr
• still compatible with overall schedule of
  electronics

11
Digital Chip ProductionTest

• pilot run delayed by 1yr
• moving into start of production

12
Gas System Production

• PRR was in December
• production of components started
• timing not critical

13
Cooling Schedule

• work on cooling unit started
• panels need to be started soon

14
DCS Schedule
15
Various

• beamtime request 2005
• alignment requirements
• t0-TTC integration
• test of TTC close to magnetic field
• connector specification
• completion of cable DB
• verification of rack layout (B-field)

16

17
B-field in UX worst case (D.Swoboda TB 27.1.04)
L.Jirden
Rack group C 50 Gauss
18
B-field tests PL500
L.Jirden

• Power module fan
• PAPST 614MN

19
B-field tests PL500
L.Jirden

• Power module fan
• NMB 1606 KL
• This fan is used to cool the double power modules
  type MDL.

20
B-field tests
L.Jirden

• VME fan tray
• Behaves similar to PAPST 614MN max 80 Gauss
  tolerated
• Ethernet transceiver
• Vacor PT4153S transformer chip tested
• Operation depends on orientation in worst
  direction all traffic stops at 200-220
• Plan rack layouts in view of water cooling only
  (racks without ventilator units) ??
