  • Director Review Dry-run updates, send task list completion dates to mark (reply Mark's email)
  • Bayesian optimization method applied to pion detector to maximize the PE. Can be applied to different optimization schemes.
  • SLAC data analysis update and conclusions by Cameron
  • Simulation software updates to develop version,
    • changes to target length 1.25 m, move the target downstream by 0.5 m, raster origin must be also moved by 0.5 m, raster size set to center of target, default beam current 65 uA, * optimizations to improve the speed of simulation,
