n1: One side working, no response on second side, chips being replaced.
Summary: We have 10 working, useable detectors. 8 are needed for E781.
Two boards have faulty svxs and no silicon are being replied.

Summary:
Tssd-Left board 1 is complete with SVX and is working, Tssd-Right
board 1 is complete and SVXs and components are being mounted and
bonded. Production of boards 2,3,4,5 for both sides will commence
as soon as the right board is fully checked out.
Tssd-Right board 1 is complete with SVXs and is being shipped from
vendor.

Summary: The primakoff silicon detectors are the old E761 beam detector
stations SD1, SD2, SD3. They have been taken over by U. of Rochester
PNPI, and Fermilab for reconfiguring into the Primakoff geometry.

Comments Side A has a noisy area from 278-320

The other smaller peaks decrease every time I eliminate
one of the noiser ones in the main peaks and will
probably vanish when the others are fixed.
