How to calibrate HES+HKS+SPL? Sieve Slit Run For angular calibration Use in proton target run? Use some reaction (e,e’e + e - ) can’t detect in E01-011 (e,e’p) Kinematic adjustment will be necessary Another reaction proton momelectron momtarget massBeam energy 1.20.9670.9381.552103411 1.31.10.9381.765073298 1.10.850.9381.357629275
