keyword=Run Summary
17:30 Done with the work in the hall and MCC is ready to send beam to the hall.
17:50 MCC called that they are ready to send pulsed beam to the hall.
18:35 Noticed that beam spot was short (less than 1 mm). Called MCC to take a
lookm at Moller quads settings. The same thing happened yesterday.
18:40 MCC called to put the OTR in for a minute.
19:25 There are tow problems right now. First, the beam spot is still too small;
about 1mm by 1mm. MCC will consult "expert" to solve this problem.
The second problem is that there are confusion with regard to cabling
of the neutron detector. Bogdan wants to make a hall access to check
the cabling. MCC is called to make controlled access to the hall in
about 10 minutes.
20:35 Done with hall access. Found few wrong HV cable connections. Called
MCC to close door to hut and to resume beam delivery.
21:20 Just call MCC to find out what's the beam status and was told that they
are recycling the Moller quads.
22:30 Call MCC to make another hall access to fix a few more cable connection
mix ups. Actually, thing is better than it sounds; we see narrow TDC peaks
(with signals from right arm) for most of the scintillator blocks. The real
to ramdom ratios in TDC for blocks in the back wall are very good.
