Abstract

PbWO4 heavily doped with trivalent rare-earth ions like La3+, Gd3+, Y3+, etc. has recently been proposed as an excellent new, heavy and radiation-hard Cherenkov radiator, and the upper limit of the remaining scintillation light yield (LY) was obtained from measurement of radioisotope γ-rays. Since then, we have made a quantitative study of the remaining scintillation LY using a 0.5-1 GeV/c π+/p/d beam. Compared with a standard PbWO4:Gd(80atppm) scintillator, the scintillation LY is quenched to 4.8%, 6.0%, and 11.6% for La3+ concentration of 8 at%, La3+ of 5 at% and Gd3+ of 3 at%, respectively. The scintillation LY remaining in PbWO4:La(8at%) was as weak as 15% of the Cherenkov LY for relativistic charged particles.
