Goals and Purpose for L-HRS during the SBS era.
Used for the HCAL calibration. Want to measure the HCAL detector efficiency by using pi+ production in gamma p -> pi+ n, as well as ep-> e' p. The pion on L-HRS is a tag for a neutron. It is a single arm trigger. It needs to be clean to 0.5% level or know the contamination on similar level. We need to remove the proton and positron backgrounds. The L-HRS is also needed for the next hypernuclear experiments (E12-15-008, E12-20-013) in hall A.
Cabling Summary
Cabling in ADC, TDC, and HV. Nominal HV values. https://logbooks.jlab.org/entry/3892105
Scintillators
Installed are the S0c, S0h, and S2m. S0c = S0 near cerenkov. S0h = S0 from HAPPEX (it is removable and likely will be removed during beam), and S2m = segmented scintillator with 16 paddles and PMTs on both sides.
