Contract Requirements

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

Requirements and Quality Assurance: Section 3 and 4 of the Statement of Work

The vendor shall prepare a Quality Assurance and Acceptance Test Plan for approval by JLab at the Readiness Review. The following items must be included:

QA and Acceptance Test Plan (Section 4.2)

A Component Inspection Plan, comprised of

  1. Inspection of all materials received from the vendor’s suppliers and subcontractors and the recording of this information.
  2. Obtaining and recording of all material certifications and analyses.
  3. The calibration and identification of standards and instrumentation used for testing; the intervals between calibrations are also to be defined.
  4. Establishment of inspection points for the incoming components, which will measure critical parameters.
  5. The recording of all inspection data in such a manner so that the history of a component can be readily traced.
  6. The submittal to JLab of all data related to the above.

A Process Quality Plan, comprised of

  1. Step-by-step process documents, with instructions and prints pertaining to each assembly and/or manufacturing step.
  2. Safety information for the job operator, including material data safety sheets
  3. A method of reporting any mechanical defects found during assembly of components.
  4. A mechanism for recording all job operator work sessions.
  5. The submittal to JLab of all data related to the above.

Final Acceptance Test Plan, based on the SiPM specification D00000-01-07-S004 Rev-A, comprised of

  1. Dark current and response to a standard light source at 5 and 20 degrees C.
  2. Uniformity of response across all 16 cells of each array.
  3. Verification and recording of operating parameters for each SiPM.

Tracking

The vendor must keep a record of all test data related to each SiPM for later use in instrumenting the Bcal modules.
