Review Check List ***DRAFT DRAFT DRAFT***
The goal of the SiPM Testing Readiness Review is to assess whether USM is ready to begin production testing of SiPM sensors for the Hall D barrel calorimeter. Specifically the following questions need to be examined:
- Environment
- 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 testing
- General
- Procedures:
- Are all procedures for receipt of SiPMs documented?
- Are all procedures for receipt inspection documented?
- Are all procedures for handling SiPMs documented?
- Are all procedures for the microscope inspection testing documented?
- Are all procedures for the PDE and Pulse shape measurements documented?
- Are all procedures for the MPPC Dark Box testing documented?
- Guidance should be given for each of the steps in the testing process for ease of estimating completion times.
- Training:
- What are the training procedures for first-time workers in each of the areas where they will work?
- How is this documented?
- Acceptance Testing
- MPPC Microscope Inspection
- Are the testing procedures clearly defined?
- Are the criteria for accepting MPPCs clearly specified?
- How is the data from this test recorded?
- MPPC PDE and Pulse Shape Measurement
- How are the units selected for this test?
- What is the cross talk between cells in the PDE test?
- How is the light source for the PDE measurements calibrated?
- Is the procedure for testing clearly defined?
- How are test data recorded?
- Are the criteria for accepting MPPCs clearly specified?
- MPPC Dark Box Test
- How are the MPPCs selected for this test?
- How are the reference MPPCs selected?
- How is the environment (temp and humidity) controlled and recorded?
- Under which conditions do the tests need to be repeated?
- Are the criteria for accepting MPPCs clearly defined?
- How is the data analyzed to determine the quantities of interest?
- Storing MPPCs
- Where and how are the MPPCs stored?
- What are the procedures for maintaining control of all units (both tested and untested)?
- MPPC Microscope Inspection
- Recovery Procedures
- What are the procedures for reporting an anomally in measurements during testing?
- What are the procedures for rectifying any problems encountered during testing? Is this documented?
- Acceptance Testing of completed module
- Are all the items listed in Section 4.2 of the SOW addressed in the Quality Assurance and Test Plan Document?
- Are any of the sensors going to be retested periodically to check stability of the setup?
- Tracking
- What information is recorded for each MPPC?
- What information is recorded for the sample of MPPCs tested for PDE and pulse shape?
- What information is provided with each shipment?
- Schedule
- How is the schedule tracked?
- Note: Time for completion of the tests at each station should be estimated based on the information to date. Re-evaluation of the schedule should be done with additional production experience.
- Reporting
- Is reporting chain within USM clear?
- Is the reporting chain to the project clear?
Contract Requirements
- Final Construction Quality Assurance Plan
- 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
- Inspection of all materials received from the vendor’s suppliers and subcontractors and the recording of this information.
- Obtaining and recording of all material certifications and analyses.
- The calibration and identification of standards and instrumentation used for testing; the intervals between calibrations are also to be defined.
- Establishment of inspection points for the incoming components, which will measure critical parameters.
- The recording of all inspection data in such a manner so that the history of a component can be readily traced.
- The submittal to JLab of all data related to the above.
A Process Quality Plan, comprised of
- Step-by-step process documents, with instructions and prints pertaining to each assembly and/or manufacturing step.
- Safety information for the job operator, including material data safety sheets
- A method of reporting any mechanical defects found during assembly of components.
- A mechanism for recording all job operator work sessions.
- 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
- Dark current and response to a standard light source at 5 and 20 degrees C.
- Uniformity of response across all 16 cells of each array.
- 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.
