R&D On Radiation-Hard Scintillators And Wavelength Shifting Fibers

With increasing beam energies and intensities of colliders, the development of radiation-hard scintillators and wavelength shifting fibers has become a crucial path in the future detector designs. The areas of implementation of such scintillators and fibers range from calorimetry to beamline instrumentation to specialized forward detectors e.g. luminosity monitors. The research on the radiation-hard scintillators falls into two categories: Quartz plates (which form a radiation-hard substrate) coated with thin, radiation-hard organic or inorganic compounds, and intrinsically radiation-hard scintillators like Polyethylene Naphthalate (PEN). Here we report on the recent developments supported with results from laboratory and beam test measurements.
