Abstract

Investigations of an appropriate thin film wavelength shifting (WLS) coatings for Cherenkov radiation detection are reported. A number of dyes were investigated and an optimum coating arrived at. This consists of 0.175 mg/cm² of p-terphenyl, 0.095 mg/cm² of bis-MSB and 16 mg of acrylic matrix (Paraloid B 72) for coating on a perspex substrate. Coating over Pilot 425 is best done with a bis-MSB grammage reduced to 0.052 mg/cm². These coatings gave an average quantum efficiency of 91% of that a quartz window PM tube over a wavelength interval of 200-400 nm. A number of hints on the techniques of utilising thin film WLS coatings are also included.
