[clas12_rgk] [EXTERNAL] URGENT: beam energy for the next RG-K run

[Eugene Pasyuk]

The requirements for beam polarization should be considered as well. It could be conflicts with other halls.

Hi Annalisa,

Stepan needs the information by tomorrow's senior staff meeting.
Let's discuss this by email.

To get the discussion going, I suggest to

  *   split the beam time between 6.6 and 8.8 GeV
  *   we should ask for 50 days 25/25
  *   keep the outbending configuration
  *   run with the FT-OFF configuration for high luminosity
Discussion should consider

  1.  importance of FT for DVCS (at lower luminosity)
  2.  Is the FTcal useful for low Q^2 spectroscopy of K-Lambda/Sigma and 2-pion production.
  3.  others

Volker

Dear Annalisa,

Can this be done via email and get answers by Tuesday?

Thanks, Stepan

Dear Stepan,
I will put this item as the main one in next RG-K meeting agenda on Wednesday. Would it be timely enough to answer before the end of the week?
Happy Easter!!

Dear Annalisa,

Another thing I want to know if RG-K will run with FT-ON or OFF or FT removed.

Thanks, Stepan

Dear Annalisa,

We are planning for t next cycle of runs. There will be opportunity to run RG-K again. I will need to know, ASAP, what beam energy you want to run, 4 pass (~8.5 GeV) or 3-pass (6.4 GeV)?
Thanks, Stepan
