v1.7.2
9722f74

Adds a real production-scale validation run for one of the six heavy-ion primaries introduced in v1.7.0, following up v1.7.1's quick smoke tests.

C12 production-scale run

  • Macros/run_C12_biased.mac: 1M-event biased C12 run (15 MeV/amu, biasCrossSectionFactor 1041, logRecoilHits enabled) through the same 10x10 um XY, 8/5 um sensitive/dead Si/SiO2 stack used elsewhere.
  • Confirmed clean: 0 exceptions, biasing engaging (476,261 confirmed interactions out of 353.5M proposed).
  • Recoil species breakdown (129 distinct species) shows fusion-evaporation residues (P, S, Al, Mg) from carbon fusing with silicon target nuclei -- a genuinely different regime from proton-induced spallation -- plus unbiased elastic Si recoils and light secondaries (alpha, He3, deuteron, triton, gamma). Max recoil LET 29.7 MeV*cm2/mg (Ni56), above silicon's own ~14-15 ceiling, consistent with prior heavy-fragment LET findings.
  • Results/Current regenerated via PANDA_Analyze.py/PANDAEX_Analyze.py against this run's output.

See README.md for details.
