NaI detector in place and working (used to measure the gamma flash).
File:Gamma flash measurement from NaI det.JPG
Asymmetry was observed for :
is the detector when placed above the target.
Detector A Asymmetry: First run = 20.27%; Second run = 19.84%
Detector C Asymmetry: First run = 12.69%; Second run = 9.16%
