Shift Summary:
------------------------------------------------------------
1.Machine status:
Not much good to say: there was a store that started before
I came with low ZDC rates (about 120 Hz). I asked MCR
to steer for us but they were a bit reluctant for some
reasons unknown to me. A funny guy from Phenix (the exp.
NOT the city :) called me and we decided to vote for a
dump around 17:45. Yet, MCR let the beams until 18:20
(they have some big problems with the famous Quench Link
Interlock). Since then, nothing. A couple of injections
that failed quickly. They finally made a ramp for conducting
hysteresis study.
2.Achievements:
Run 5482 ended 16:05, MRS 4B - FS1/2A 52k tr1 - 15.7k tr6
Run 5483 16:08-16:36, MRS 4B - FS1/2A 28k tr1 - 8.7 tr6
stopped it because MRS 4B goal achieved
Run 5484 16:38-16:43, small run with wrong current in D5
(600 Amps instead of 500)
Run 5485 16:44-18:42, MRS 3B - FS1/2A 54k tr1 - 16k tr6
stopped cause beam dumped by MCR
Detector pedestal run 5486
TPC pedestal run 5487
3.No detector problems at all (since we were in a stand-by
mode most the of the shift).
Flemming changed something in the FEH around 16:00: he
added a capacitive decoupling to retime the CDF with
the BB but as far as I know, it was not a success and
gave a bigger offset.
