Cf-252 Runs with PMTs, Large Scintillator Slab, Neutron Capture Efficiency
Experimental Set Up: 2" PMT attached to bundle of 4 fibers
Results and Analysis: 2" PMT attached to bundle of 4 fibers
Experimental Set Up: 1" PMTs attached to individual fibers
Results and Analysis: 1" PMTs attached to individual fibers
Conclusions
It was concluded that PMTs could not resolve the desired number of photoelectrons from the slab. Instead, the PMTs coupled to the optical fibers should be replaced with SiPMs.
