INCREASING THE LIGHT COLLECTION EFFICIENCY OF SCINTILLATION COUNTERS
Technical Report
·
OSTI ID:4731801
A systematic study was made of methods of increasing the light collection efficiency of scintillation counters. Various reflectors, surface treatment of the scintillator, relative geometries of scintillator and photodiode, and light pipes were tried, using plastic scintillator cubes. 3 and 6 in. on a side, and right circular cylinders, 3 in. in dia. by 3 in. in length and 6 in. in dia. by 6 in. in length. The maximum factors by which light output could be increased, relative to a polished scintillator, were: about 2.8 for 6- in. scintillators and 3.3 for 3-in. scintillators without the use of light pipes, and 5.0 for a 3-in. scintillator with light pipe. The fraction of light trapped in a right circular cylinder by total internal reflection is derived as a function of index of refraction, as are the percentages of light coming out the ends and sides of a cylinder.
