GEM linearity studies for SBS-8 kinematic is attached.

Beam current went up only to 5 uA on LH2. However, we can see that when compared with SBS-14 linearity study ( see here https://logbooks.jlab.org/entry/3932489) GEM excess currents are comparable to 10 uA beam current, on LD2 in SBS-14 to 5 uA beam current, on LH2 in SBS-8, confirming high background rates of SBS-8 due to the smaller BB angle (24.0 degrees).
