Scintillating Fiber Performance in high Pressure Noble Gases

摘要

The use of scintillating fibers to collect the scintillation light produced by electrons drifting in a noble gas is discussed. The imaging of photons in the 10 to 150 keV range is discussed and light yield produced by photons in this range is estimated. Results are presented from an experimental setup to measure the change in light yield of scintillating fibers as a function of time while in a 20 atmosphere Noble gas environment. An upper limit of less than 5~.-10~(-5) per day was obtained on the change in fiber brightness as a function of time.
