Meeting 6 December 2019

AGENDA COLLABORATION MEETING

• KLong talk (Sean) plus invite people for (informal) discussion about next steps - perhaps invite a local theorist

• Possible theorists for DVCS/TCS/WACS - contact a few about availability (talk could be given remotely)

MAGNET

• Status of vendor discussions about radiation hard coils

• NZ - no radiation hard epoxy
• PPPL/ITER - expert contacted
• Florida High Magnetic Field - expert at ORNL contacted
• JPARC/Tanaka - two companies contacted

SIMULATIONS

• From an Hall B ERR learned that some GEANT4 versions fail to reproduce experimental data on neutron production - this may explain the observed difference in CPS simulations 2015 and recent FLUKA

• observe three order of magnitude drop in cross section in latest compared to earlier GEANT4 versions
• new GEANT version released is better after putting in photodisintegration, but still some problems

• CPS simulations are in FLUKA - for now better to stay with this

• compatible with GEANT4 for physics projections

• Current CPS status: have new target magnetic field and made initial projections for radiation level at the coils - optimized simulations expected soon

• TCS simulations: help from TCS proponents needed

ARTICLE

• Two small outstanding issues to address - expect to have this done and post to the arXiv soon

FUNDING PROPOSAL

• due January 20, 2020

• need magnet cost

• Cost share details

NEXT MEETING: FRIDAY 20 DECEMBER AT 11:00AM (ET)
