MARATHON Production Run

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

Kinematic point 1 (x = 0.218)
