TPC

  • dE/dx in thresholds.nb
  • TPC study with Garfield and ROOTon work/htpc
    • ReviewStudy.pdf
    • htpc.cpp, has also interesting numbers
    • use run for Garfield studies, tpc.in is the input file
    • tpc6500.out: Garfield output, e5500.dat e-filed file, tpc5000.ps graphics files

TPC

  • dE/dx in thresholds.nb
  • TPC study with Garfield and ROOTon work/htpc
    • ReviewStudy.pdf
    • htpc.cpp, has also interesting numbers
    • use run for Garfield studies, tpc.in is the input file
    • tpc6500.out: Garfield output, e5500.dat e-filed file, tpc5000.ps graphics files
