Runs Digest

The following is a digest of the T9 runs. Get the full list or the selected run from the pipeline or elogbook. (WORK IN PROGRESS).

In red color : Not to be used, due to mistake, or for specialist. 

In blue color the runs numbers good for the statistics 

Last run taken into account : 1334

this run is to see if the zero that we see is a trigger or magner problem: it seem that it's a trigger issue: now the fraction of zero seems similar to what we saw in the other physics runs.

Trigger is standard : S0.S2.S4.C1.C2.veto(S3+Sh)
Magnet Current set to 300A to shoot the beam directly in the Tagger.
300A is not enough trying to go up to 320A and then to 350A and then to 400A
400A is OK, Stopping run and start the Good On

 1281  13/8            Pedestal- Trigger is now only S0 and the beam is off...have only muons deviated by the magnet.
We used to trigger on S3 when it was out of the beam, but now it's on the beam line, so we had to find a new strategy !

  • we start with 240 A that is too much: the beam miss the lead and enter the CU side.
  • second setting is 200A, it seems better. let's scan more current to be sure.
  • magnet 160 A, beam is bent too much... etc..
