Minutes of the Trigger Operation Meeting (26th June, 2007)

Operations

• Recieved email from DQM over the weekend about GLT JAS instructions. They've been clarified. Also made a note on L3 JAS page that L3 EMC plot is rotated compared to the EMC system plots.

EMT

• Broken board still with Lupe.
• New EMT cellphone arrived - the number stays the same.

DCT/DCZ

• Problems over the weekend with the DCH - see hypernews discussion. They will replace the electronics box tomorrow.
  • Should check TRG plots to see if this has caused any problems in the DCT.
  • They have not masked out any layers yet but may have to today if the electronics fail completely. In this case, we'll not have enough layers for a B track. We can alter the BLT mask to set the relevent bit to 1 which will regain efficiency at expense of backgrounds.
  • Should perform a DCH-DCT calibration after the work is done.

L3

• MC validation of new L3 tracking still up for grabs. It really should be implemented by the end of this Run.
• Hojeong has been having trouble with L1TNtuple - see hypernews posting.

Data Quality and Monitoring

• Run 6 TRG stripcahrts are ~90% done.
• Rahmat is in the process of obtaining an account at Padova.
• The DQG has noticed the pi0 mass goes down as the backgrounds increase. This is curious.

Trigger Configuration

• The study still needs validaation on SP9 MC.
• The propsed 1E trigger line requires a re-think of L3 flags. The BGFilters are nearly ready, so L1 and L3 will soon be the issues preventing implementation.
