The PMTs of selected paddles, paddle 1 to 19 are regular width/length paddles, paddle 20 and 21 are narrow width long paddles and paddle 22 is a short single ended paddle. The rates are in Hz as a function of beam current in nA. The data are from runs 11634 to 11637 where luminosity scans were done from 40 to 140nA. The collimator was set to 5mm diameter and the radiator is 3x10-4 with LH target full.:
