Description
The FEU-187 15-stage photomultiplier produced by RIE was tested at PNPI
for its suitability for calorimetry in very forward regions at colliders. At levels
expected in the LHC environment, it is radiation hard, resistant to magnetic
fields, and unaffected by the presence of helium. It has an excellent time
resolution of 58 ps, measured in time of flight measurements with 1.8 Gev/
c beams of pions, kaons and protons at CERN and of 270 ps, measured with
an ultrafast laser diode in single photoelectron mode.
