AFE IIt Project Status

DD Current Status

AFE II Prototype Testing Complete Detailed ch by ch testing has been done

3071 good channels out of 3072 through comprehensive test Continuing with some long-term (weeks) testing of cryo

control and stability on the VLPC CC cryostat Packaged TriPt (MOSIS) in house TriPt/FPIX submission - OUT Design input for AFE IIt board finished Schematic Complete – 6/20 4 weeks behind - but Layout Complete – 6/28 about 2 weeks behind

We have authorized OT and it is being used Will try to add a second Layout tech towards the end.

For technical reasons this is not appropriate at this time Only issue

Could use 1 additional person to work on FPGA programming

TriPt: Packaged “MOSIS” parts are here Robot tester work progressing: adapter

board in layout (estimate: 1 week) Mechanical parts for robot complete

DD Response to Recommendations from Director’s Review

We have modified the project plan to include: A second submission of the TriPt chip

This, of course, does produce a delay in the project completion. The funds are there if needed, however

We believe that the probability for a successful run is very high

Production of 350 boards. Over time for layout technician(s) for AFE IIt board

Bob Demaat has joined the AFE IIt project as L2 production manager

Weekly reporting will occur via the AFE IIt production meeting with progress and schedule status from the L3 managers written up and published as minutes of this meeting
