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. |
