PID goal for L-HRS

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.
