Construction News
The three counters from McNeal arrived two weeks ago. The package was
visibly crushed on the outside and one of the counters was in pieces.
The other two had scratches on the surface. FIU is trying to recover
the cost from the shipper.
Testing will proceed with the two scratched counters. Scratches on the
surface have not necessarily degraded performance in the past and other
that the counters look good, with well-polished edges.
FIU is updating the test stand to enable reproducible testing of
multiple counters as they arrive. They plan to do test with sources and
with cosmics.
Eric did not receive the model of the counter from Chuck. Chuck will
re-send.
Read-Out
The ST2 board at FIU is damaged. The lemo connector on the PCB is
broken. Mark will ask Fernando Barbosa to give Eric a call to provide
guidance on re-soldering.
Sascha reported that the SiPMs for the start counter are due in the
middle of November. FIU is interested in getting a read-out board with
all three channels populated (12 SiPMs).
Contract
Werner sent a version of the SOW to Mark wihich include a timeline for
construction.
Mark has started writing the sole-source justification.
