T18_vg2.4_disk_#2 break down position 252 ns data
T18_vg2.4_disk_#2 break down position 252 ns data (DPO run 32) Missing energy of breakdown-2 pulse Missing energy of breakdown-1 pulse, Mainly calibration error and noise on signal
T18_vg2.4_disk_#2 break down position 252 ns data (DPO run 32) Statistics: 384 events, 105 with missing energy > 20%, 121 with fc upstream < -1, 111 with fc downstream < -1, 105 with both < -1, 67 events gave a reasonable cell No. Finding a reasonable cell umber depends on noise on signals, some events have very little reflection Histogram of the time delay between reflection and transmission, in structure (0-38 ns), earlier often no reflection or noise on reflection, later sometimes very late reflection and no missing energy

T18_vg2.4_disk_#2 break down position all data together
T18_vg2.4_quad_#5 DPO run 11, 113 ns Statistics: 400 events, 378 with missing energy > 0%, 379 with fc upstream < -0.03, 382 with fc downstream < -0.03, 369 with both < -0.03, 297 events gave a reasonable cell No.

T18_vg2.4_quad_#5 DPO run 11,12,13,17, 113-293 ns
T18_vg2.4_quad_#5 DPO run 17 Strange asymmetric reflection, no breakdown, no faraday Cup signal
T18_vg2.4_quad_#5 DPO run 17 Strange after pulses, Some events have quite high reflection, in addition normal reflection is quite significant (right plot), is this calibration or mismatch ?
T18D_vg2.4 DPO run 8, 50ns
