NEWS:
Steve said that the summer shutdown schedule was discussed in the operations
meeting. The window of oppotunity is defined by some known constraints and it
is known to be between July 28 to the end of October. If they meet integrated
luminosity requirements by the time, it would happen in between September
to October.
Vacuum problem happened during the flying wire replacement work in the recycler. The bearing replacement had oil as lubricant. They need one or two day access for the bearing and to replace the 200 meter section of the contaminated beam pipe.
SYSTEM:
Steve said we need to install software trigger inhibit for CLC and PLUG
systems. Andrea is going to work on CLC. Luciana is sending a new pc
to FNAL. We hope this will solve the problem of making excutable with
iFix version 3.0. This PC has PCI card rather than ISA card.
ICICLE:
The Oracle database access problem was solved after the experts figured
out how to combine time stamp index and history index. It sped up the
access time by factor of 100.
MUON:
When the main muon picture is opened at a PC other than MUON3, it cause havoc.
This happened during a data taking at Vnode2. This caused trigger inhbit and
resulting halting DAQ. Yeongdae said he will have a look. He can solve the
problem or make a quick fix by disabling the picture when opened at any
pc other than MUON3. Yeongdae also promised to work on the HV feedback code
for CES, CPR and CCR.
SVXIICON:
Andy said he looked into code and found that the readout cycle for SVX systems
is about 8 seconds but the writeout interval is 40 seconds. He modified the
code to write only important tags every 8 seconds. The other 9000 tags were
written in every 10 minutes to match the ICICLE read out cycle. Steve offered
a new video card for the SVXIICON.
PSM:
Marcin said he is leaving on May 21. Dan Ryan (Tufts grad student) is coming
this weekend to take over his responsibility.
