TRACK SIMULATIONS CONCLUSION NEXT STEPS
Start-to-End simulations (from RFQ to stripping
foil) implemented into TRACK
The 1.7 km beamline runs on parallel (64 CPU) at
ANL-BlueGene computer Takes 1H18 mn to perform,
200k particules.
NEXT STEPS IN HINS SIMULATIONS
1/ Halo Studies (1M to 80M particle distribution
on 64 to 256 CPUs)
2/ Jitter Misalignment Studies (up to 100 CPU
on ANL-JAZZ computer)
3/ Implementation H-minus stripping into TRACK
(Magnetic, Residual Gas and Blackbody radiation)
