Back to 2018 Spring Run

Back to Tritium Main

  • d/u DIS run (HRS-L Only, Jan/12 to March/22 2018 Run):

DIS-Run (Jan 2018 Run, E0=10.6 GeV, E'=3.1 GeV/c)

HRS-L

Scan of gas cells (empty, 3He, 1H, 2H, 3H) completed twice. For these targets:

  • Run time given is per scan of cells (i.e., total run time of both scans is 2x time listed)
  • Runs marked * were taken on the second scan of cells
