Radiation hardness study on fused silica

Development of a pulsed UV laser system for laser-desorption mass spectrometry on Mars

“…As far as possible, fused silica, which is known to be radiation hard [5], is used for optical components except for lenses and the crystals. The aspheric lenses in the prototype model are made of Co550 and will be replaced by radiation hard material SF6G05 in the EQM.…”

The Focusing Disc DIRC for the PANDA experiment at FAIR

“…This novel technique provides a compact and fast detector for particle identification. Synthetic silica is chosen as disc material as it is sufficiently radiation hard for the anticipated lifetime of the PANDA experiment [7]. The disc has a radius of approximately 1 m, a thickness of around 15 mm and a central opening matching the acceptance of the forward spectrometer.…”

The P̄ANDA Experiment at FAIR

“…Readout either by a two-dimensional position sensitive detector [7,8], or by a one dimensional position sensitive detector along the rim records the Time-of-Propagation (TOP) of the photons [9]. In the first case the light is coupled out from the disk by a focussing light guide towards the photon detector.…”
