  Dear all,

  Here is a brief up-date of the current status of the experiment and planned
  work over the coming days.

  - Accelerator :

  The work at the CHL is still on-going. As now, no major leak was found
  and the plan is to start coming back on operation mode over the week-end
  if vacuum is satisfactory.

  - Hall :

  Hall A will go to power permit in the afternoon (2-3 pm) to allow energizing
  the ARC magnets for measurements related to the beam energy measurement
  system. This will last about half a shift, after which we'll go back to
  restricted access.

  - DVCS Detector :

  The calorimeter cabling test is on-going.

  - Running :

  The plan after the week-end is to move on 5 pass beam and start data taking
  at this energy. Electron spectrometer and calorimeter angles will be set on
  monday morning and the calorimeter will be surveyed.

  Beam delivery to the experiment is still scheduled on wednesday. From monday
  4pm, shifts remain on stand-by.


  Regards, Eric
