The lower limit on operating temperature has not been set, but research experiments have used fiber in temperatures down to about 4 degrees K. Fiber will lose their flexibility at low temperatures.
All scintillating fibers are sensitive to fast neutrons through proton recoil.
We define the light output as # of photons per MeV for minimum ionizing Particle, which is approximately 8000 for BCF-12. The more densely ionizing particles emits less light than per unit energy.
All scintillating plastics are about 1.58. For complete Physical Constants click here.
The tool is a diamond tipped tool, but the actual parameters and methods are considered proprietary.
Yes, this is a case by case basis and needs reviewed by the Application and Technology manager.
No, only the thickness, the remaining 4 sides can be rough cut, or diamond milled. For round parts, depending on dimensions, most of the time the thickness is as cast, and the outside diameter is diamond turned. For parts that are closer to a rod than a disc, both the out diamter and the length would be diamond turned.
This depends on size, and quantity. These are made by hand, so huge quantities would not be practical, but for laboratory trials, it is possible to make plates 10mm square x 100µm. For plates as large as 25.0mm square, the minimum thickness is 200µm
