2515 Up
90A		 In Open In Yes Out DU cylinder Test radiator in/out.

144632 pulses
R(bottom) = 3.4E-5 n/pulse -> × 180 Hz × 60 sec/min = 0.37 n/min
R(upstream) = 8.57E-4 e+/pulse

2517 Up
90A		 In Open In Yes In DU cylinder Test radiator in/out.

0 pulses
R(bottom) = 8.97E-4 n/pulse -> × 180 Hz × 60 sec/min = 9.69 n/min
R(upstream) = 17.7E-3 e+/pulse
About 95.2% of photons are coming from the radiator according to PS.
