Check of calibrations and rates for neutron detectors with Conf File 161107Conf_BrikenFull.xlsx Measurement 161122_2208_003.root has been used to check the calibrations and counting rates in the BRIKEN detector. Condition of the measurement: 252Cf at 22.5cm from moderator, opposite sede from AIDA RESULTS Calibrations factors: Calibrations of the neutron detectors are reasonable in the current conditions. A check detector by detector (see attached file) shows that the full peak for most of the counters is around 764keV. Only 3 counters are shifted more than 10keV: He134 741.901 He135 750.312 He140 748.587 The impact on the counting rates would not be serious. Counting rates (n/pulser): ######################################### Total neutron rate: 1516.28 ######################################### BY RING: ######################################### R1 359.057 R2 222.997 R3 386.299 R4 253.833 R5 143.434 R6 90.6357 R7 60.025 The total current counting rate is lower than rate obtained in Oct 12th (total 1550.91 n/pulser). The difference is due mainly to a decrease in the counting rates for rings 1 to 4.
