So after some attempts we added a large scintillator below the detector to reduce the angle of detected muons. The rate went down to 1 muon / minute. | run | DAQ state |HVapp | comment | IBot | ITop | Eff | P | T | HVeff | |739972|FE1_24CH_29|7100| Currents of bottom gap rising| 1.52 |3.66 | |967|23.8|???| === Session APRIL10: NOISE THR = 491 + 15 = 506 units === | run | DAQ state |HVapp | comment | IBot | ITop | Eff | P | T | HVeff | |739974|FE1_24CH_29|7100| 19.20-19.30 / 23.04 - leds| 1.4 |3.60 | |965|23.3| | |739975|FE1_24CH_29|7100| 19.33-19.43 / 23.04 - no leds| 1.6 |3.50 | |964|23.1| |
