- STA sent the test report of our detector. Everything is in spec, QE is good. Fringing
looks a bit high due to some of the coating not filling in properly. Actual number is around 0.8%. They are going to retake the data at 800 nm and it should look much better. There are three specific places where the fill is a problem. Overall, Joe is happy with the results.

· No plot or picture yet, they are sending it in a few days. · Gain of 2 for these tests. · We will do our own full-well and linearity tests, up to 65,000 counts. · Can we ask them to test up to 65,000 counts? · We want to accept pending our own tests. - Plan to integrate at the end of April. · Open the dewar, take everything out, remove old chip, insert new chip. Add the
new heaters and wiring. All done in the clean room.

· John wonders if we should raise the clean room humidity? Joe will ask Connie and
Jim.

· We do not get to keep the backup chip. - Fritz has the ICC working, and is working with Conor to verify the software. - Will start building the cart. - 2 of 3 optics are done. The last is being coated right now.
