Announcements

Items from previous meetings

  • Eugene looked at the problem of the optimal angle of the photon beam but does not have plots to show yet. He will send some plots after the meeting.
  • Vitaly identified that the high does rate before the CPS is due to the radiator.


Simulation updates

  • First we discussed where CPS could potentially located. The consensus was that it should be in-between the tagger magnet and the permanent magnet in the tagger hall .
  • Vitaly considered a few examples of magnets that could be used for CPS with different length: 75cm, 145, 300cm.
  • The energy depositions did not show much improvement and the length of the 300cm magnet was much larger than the spread.
  • Pavel, Eugene and Hovanes pointed out that the most important issue for choosing or designing the magnet is the heat deposition spread.

Action items

  • Angle of photon beam with respect to the nominal beam line (Eugene, Moskov)
  • Simulations of the dose rate without the radiator (Vitaly)
  • Determine a data format for the energy deposition file used for temperature calculations .
  • Hovanes will talk to Bogdan regarding the magnet choice.
