Data were collected on unpolarized D2 up until almost noon. All runs have
been crunched. In the meantime, work was proceeding upstairs to diagnose
the SFT problem. The South Hall was open for the afternoon for
ABS-related work and is being secured presently. The spin flipper was
also prepared for operation during this interval.
Genya reported on ABS group's findings and proposed modifications to SFT
which will be performed before it is re-installed. These include silver
plating the leads to improve thermal conductance as the unit is
overheating. No definite time for re-installation of ABS could be given;
the absolute earliest possibility would be to start late tomorrow.
Plan for tonight is to run more unpolarized D2. We will also run spin
flipper tonight in preparation for a measurement to be made tomorrow night
to measure the spin tune of the Ring (Fuhua, Jan, Townsend, and me will
carry out). I will set up flipper before leaving.
Beam delivery will cease at 7:00 a.m. tomorrow morning to open Hall in
preparation for Snake fill and transmitter work. Beam will remain off
until 20:00 for the transmitter work.
