Time Cuts

The first step in the PAA process is to identify the time cuts used for the split run. This must be done for all samples (50%,10%,0.1%, and 0.04%) Let's do the 50% sample first

50% Sage/Se Mixture Time Cuts

The 50% Se/Sage mixture was measure on Detector B (unshielded, so watch the SNR) on 5/24/17 for a total of 2130.540 seconds. The outer pure witness Se was measure first, and sub-run was roughly 300 seconds for the samples of interest, and 60 seconds for the Co-60 flag. The root command used to draw the timing information was

TTree* tree = MPA;

MPA->Draw("evt.Chan:evt.Sec>>hist2","evt.ADCid == 1");

which produced the histogram below

This seems a little sloppy, lets try a 1D histogram instead to see if the cuts are more clear

ROOT Command: MPA->Draw("evt.Sec>>hist","ADCid==1","");

This produced the histogram below

This seems much cleaner and clearly shows the time cuts

10% Sage/Se Mixture Time Cuts

The 10% Se/Sage mixture was measured on Detector A (shielded) on 5/25/17 for a total of 5136.343 seconds. The mixture was measured first, and a sub-run was roughly 300 seconds for the Se samples and 60 seconds for the Co-60 flag. The root commands used were

TTree* tree = MPA;

MPA->Draw("evt.Chan:evt.Sec>>hist2","evt.ADCid == 0");

The time cut information is as follows

0-300 (Mixture) 300-360 (Co-60) 400-640 ( Pure Se) 680-710 (Co-60) 730-1020 (Mixture) 1030-1080 (Co-60) 1100-1360 ( Pure Se) 1400-1440 (Co-60) 1480-1775 (Mixture) 1800-1840 (Co-60) 1875-2150 (Pure Se) 2190-2220 (Co-60) 2250-2550 (Mixture) 2590-2620 (Co-60) 2650-2930 (Pure Se) 2950-3000 (Co-60) 3050-3300 (Mixture) 3390-3350 (Co-60) 3400-3690 (Pure Se) 3700-3750 (Co-60) 3775-4050 (Mixture) 4060-4100 (Co-60) 4120-4400 (Pure Se) 4420-4470 (Co-60) 4480-4770 (Mixture) 4790-4820 (Co-60) 4840-5130 (Pure Se)

0.1% Sage/Se Mixture Time Cuts

The 0.1% Se/Sage mixture was measured on Detector A (shielded) on 5/24/17 for a total of 2130.540 seconds. The mixture was measured first, and a sub-run was roughly 300 seconds for the Se samples and 60 seconds for the Co-60 flag. The root commands used were

TTree* tree = MPA;

MPA->Draw("evt.Chan:evt.Sec>>hist2","evt.ADCid == 0");

which produced the histogram below

This seems a little sloppy, so let's repeat the procedure for the 50% sample

ROOT Command:ROOT Command: MPA->Draw("evt.Sec>>hist","ADCid==0","");

This produced the histogram below

This is again much better than the 2D histogram.
