Title: Electrical Testing during Barrel integration


1
Electrical Testing during Barrel integration
  • Doug Benjamin
  • Duke University

2
Discussion points
  • Two testing phases
  • During module insertion into space frame (either
    layer by layer or sector by sector)
  • ? Able to remove modules or boards relatively
    easily at this stage
  • Final testing after all modules installed, final
    manifold added and the outer cylinder attached

3
Testing During first phase
  • Test 1 end of a module at a time
  • HV test of module with ArCO2
  • Threshold scan
  • Check if the electronics works
  • not 100 certain if wire connected to electronics
  • Source scan Cadmium 109
  • Source can shine through entire type 3 module
    see of all straws are connected to electronics

4
What do we need for this testing?
  • Cables and patch panels between AR boards and
    Rods.
  • Can we use the preproduction cables between AR
    boards and PP2? Need the final PP2 design. If
    Nandor is not designing AR boards Can he do
    this?

5
What do we need for this testing?
  • HV system
  • CAEN crates
  • DCS control software
  • Production fuse boxes?
  • Interface box between SHV connectors and fuse box
    connectors.
  • LV system ?

6
What do we need for this testing?
  • Cooling
  • Use chiller of building need controller and
    flow regulators for integration testing
  • Callahan chiller and control system for system
    testing (2 sectors) and 2004 beam test

7
What do we need for this testing?
  • Software
  • Board on Module testing
  • Standalone board acceptance tests
  • Working boards, acceptable performance?
  • Straw- electronic channel mapping
  • Module performance
  • User-friendly, open system
  • Common interface with analysis tools. New people
    on board knows what to look for and how, quick,
    easy and adaptable by user..
  • Accumulate experience for ATLAS TRT integrated
    monitoring

8
What do we need for this testing?
  • People
  • Experts Penn (Toni, Mitch already working on..)
  • New person Ben LeGeyt (BS physics) will also
    help with system testing
  • I am planning of other members of the TRT
    collaboration to participate in shifts if needed.

9
Barrel system tests
  • Critical item to solve as soon as possible -
    grounding and shielding
  • Need to start cooling plate fabrication.
  • test grounding clip schemes initially with type
    1 modules
  • Scope will have adiabatic growth as new boards
    are delivered must be done quickly though
  • Cosmic rays?

10
Other points
  • Not much time
  • Need write meaningful specifications
  • Can not steal equipment from SR-1 for 2004 test
    beam
  • Need to plan to do both barrel assembly and the
    2004 test beam - Resource limited people and
    parts!
