• Work on Technology (mechanical design, optic simulation)

• Increase photocathode homogeneity and sensitivity

• Faster: New design with the “double anode concept” (addition of a screening grid at the anode)

• First results on 2” XP20D0

Faster PMTs ?

PAVI 2006, Milos, Greece

• Program to consistently achieve QE > 40 % @ 400nm

• High QE% to improve PHR for standard NaI(Tl) crystal coupling

• Industrialization in progress
