FCAL Fabrication Readiness Review Checklist ***DRAFT DRAFT DRAFT***

Review Check List

The goal of the Forward Calorimeter Readiness Review is to assess whether the University of Indiana is ready to begin production of the fabrication of the Hall D forward calorimeter modules. Specifically the following questions need to be examined:

  1. Environment
    1. General
      • Are the MSDS information sheets available for all products used during production?
      • What support do you get from university EH&S services?
      • Are there any materials (e.g cleaning agents/etc) that are of particular hazard during fabrication
  2. Procedures:
    1. Are all procedures for accepting fabricated parts documented?
    2. Are all procedures for assembling components documented?
    3. Guidance should be given for each of the steps in the fabrication procedure for ease of estimating completion times.
  3. Training:
    1. What are the training procedures for first-time workers in each of the areas where they will work?
    2. How is this documented?
  4. Acceptance Testing
    1. Lead glass
      • Are the testing procedures clearly defined?
      • Is the criteria for rejecting glass blocks clearly specified?
      • How is the location of each block recorded?
    2. PMT
      • How are the dimension tolerances checked on pmts?
      • How is the performance checked?
      • What performance characteristics are recorded?
    3. Machined parts
      • What acceptance will be performed to verify dimensional tolerances of all features of the machined parts?
    4. Assembly
      • How are the mechanical tolerances checked after assembly?
      • What documentation is recorded for each module?
  5. Recovery Procedures
    1. What are the procedures for reporting an anomally in measurements during the assembly?
    2. What are the procedures for rectifying any problems encountered during assembly? Is this documented?
  6. Acceptance Testing of completed module
    1. How are the dimensions checked and verified against drawings?
    2. How is the uniformity of transmission determined?
    3. What criteria are used to accept a completed module before shipment?
    4. How are the modules going to be checked with cosmic-rays?
    5. How many modules will be tested with cosmics?
  7. Tracking
    1. Are all travelers specified for the project?
    2. What information is recorded for the fibers?
    3. What information is recorded for the lead?
    4. What information is recorded during matrix fabrication? How may for each layer?
  8. Schedule
    1. How is the schedule tracked?
    2. Note: Time for completion of a module should be revisited after completion of the first two production modules.
  9. Reporting
    1. Is the reporting chain to the project clear?

Contract Requirements

  1. Final Construction Plan
  2. Final Acceptance Test Plan
  3. Quality Assurance Plan.

Testing and Tracking: Section 5 of the Statement of Work

Testing

The vendor shall include a draft Acceptance Test Plan with their contract proposal with the final plan to be formally approved by JLab at the Readiness Review. The following items must be included:

  1. Acceptance of lead sheets upon receipt
  2. Acceptance of fibers upon receipt
  3. Acceptance of swaged lead sheets
  4. Acceptance of fibers during sorting
  5. Dimensional tests of aluminum base plates
  6. Dimensional tests of lead-scintillation matrix during stacking
  7. Acceptance of completed modules based on the following criteria:
    1. Dimensional testing of modules after machining
    2. Measurement of light transmission of completed modules.
    3. Determination of the uniformity of transmission across the face of the BCAL module, e.g. digital photos showing the number of damaged fibers.
  8. Measurements of the response of a sample of completed modules to cosmic rays.

Tracking

The vendor must keep a record (travelers) of all raw materials and inspections that are used in the construction of each module, and document the procedures followed during fabrication.
