Fcal Readiness Checklist

DRAFT DRAFT DRAFT FCAL Fabrication Readiness Review Checklist DRAFT DRAFT DRAFT

The goal of the Forward Calorimeter Readiness Review is to assess whether the Indiana University 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?
   2. Lead glass
   3. Cockcroft Walton bases
2. Procedures:
   1. Are all procedures for handling lead glass documented?
   2. Are all procedures for assembling modules documented?umented?
   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. Pmts
   2. Lead glass
   3. Machined parts
   4. Completed modules
      • Which measurements, and what frequency is planned during assembly?
      • What documentation is recorded at each stage?
5. Recovery Procedures
   1. What are the procedures for reporting an anomally in measurements?
   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 light transmission measured for a completed module?
   3. What criteria are used to accept a completed module before shipment?
   4. What testing will be done to verify performance?
   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 pmts?
   3. What information is recorded for the lead glass?
   4. What information is recorded during assembly fabrication?
8. Schedule
   1. How is the schedule tracked?
   2. Note: Time for completion of a module should be revisited after completion of the first batch of 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.
