Abstract: | Polytetrafluoroethylene (PTFE) is an excellent diffuse reflector widely used in light
collection systems for particle physics experiments. In noble element systems, it is often coated with
tetraphenyl butadiene (TPB) to allow detection of vacuum ultraviolet scintillation light. In this work
this dependence is investigated for PTFE coated with TPB in air for light of wavelengths of 200 nm,
260 nm, and 450 nm. The results show that TPB-coated PTFE has a reflectance of approximately
92% for thicknesses ranging from 5 mm to 10 mm at 450 nm, with negligible variation as a function
of thickness within this range. A cross-check of these results using an argon chamber supports the
conclusion that the change in thickness from 5 mm to 10 mm does not affect significantly the light
response at 128 nm. Our results indicate that pieces of TPB-coated PTFE thinner than the typical
10 mm can be used in particle physics detectors without compromising the light signal. |
