Discussed about two chamber target design and recent model calculations done by Silvu on PREX-I target heat issues and a rotating lead target. See elog-2978 for two chamber target design update

Bob, Ciprian, Caryn, Rakitha, Seamus, Paul



  • Two chamber target design discussion
    • The current collimator box would not fit a 30 cm diameter beam pipe and needs to be changed accordingly
    • For now simulate with smaller beam pipe to fit the collimator box
    • Compare radiation numbers
  • Since we are going to run PREX CREX combined mode, add proposed PREX+CREX merged collimator desing
    • Two collimators will be merged vertically and drops from the top. At the end of two experiments the merged collimator will be dropped to a box under the collimator box
    • Therefore it would be important to have similar design in the simulation
  • There are still discussion about the possibility of rotating lead target by Roger and Silviu has done some model calculation about PREX-I target heat issues and potential rotating target design.
    • There are lot of issues needs to addressed about this design and currently as a collaboration we don't have resources to look in to this alternative design.
    • Silvu's report will be posted by Bob later


  • Beam parasitic studies needs a to-do list

  • It would be nice to have real-time viewer for optics studies in commissioning (disussed in 01/16/2014 meeting)
