June 4th Update

The first task: To estimate the Flex cable length (my suggested version), will come Thurs June 6th.

In terms of our schedule (for the HEP Imperial workshop & HEP imperial Design Office), we will proceed with two physical models, both are for the Mono-layer, Perpendicular End Cap (MLPEC).

MLPEC_01: A quarter length End Cap, for 4 siPms. Simply to show people that cannot visualize the CAD.

MLPEC_02:: full length End Cap, for 16 SiPMs.

It is important to remember that these “models” aim to aid visualization and general understanding. For example, they will not connect to a cooling rig. My CAD models will be presentable to our workshop on Friday 7th(Discussion Monday 10th).

1) Production of “End Cap Model _01” starts on Monday 10th June.

2) Assembly & presentation of “End Cap Model_01” scheduled on Friday 28th June.

3) Procurement of materials and components for “End Cap Model_02” will take place In parallel with #1. & #2.

4) Production of “End Cap Model_02” scheduled to start Monday 1st July.

5) Production of Alignment jigs for “End Cap Model_02” planned to run in parallel with #5.

6) Test assembly of “End Cap Model_02” to be reviewed The week starting 22nd July.

7) Assembly of “End Cap Model_02” scheduled to take place July end\August beginning.

8) August will see reduced manpower availability.

9) Review in-house status at the end of August.

10) During all of the above, the design will develop and design effort will be ongoing.

Areas for attention:

  • Simplification.
  • Manufacturability.
  • Assembly.
  • Bonding requirements\sequence.
  • Positioning jigs\fixtures (already discussed with our workshop).
  • Handling jigs\fixtures (already discussed with our workshop). In Parallel:
  • Material selection (the real materials).
  • Temperature compensation (accuracy Vs Over constraining).
  • Flatness of the long carriers and possible distortions for SiPM plane.
