Noticed high voltage S2X3+=2427,S2X8+=2828,S2X8-=2401.... Was on 1/8/00=2375,2565,2342 resp.
HCF phoned MCC at 15:45 to ask why we have not had beam all afternoon
(the MD period was scheduled to end at 1200)... MCC would not tell
me and told me to phone the PD. I tried the PD cell-phone and got
the "phone not in service" message. Phoned Hari Areti who researched
for me: the afternoon downtime was caused by a change to 4-pass in
Hall-B (MCC had told me that, but had denied that was the reason
we were off since noon).
Hari said that a pass change of this sort always (automatically) gets 4 hours.
I guess we were supposed to know this somehow???
The PD's cell phone, it seems, often does not work if it happens to be
placed in a certain orientation near a piece of metal. How convenient!
I wish my pager would do that.
