• 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 ?

• Program to consistently achieve QE > 40 % @ 400nm
• High QE% to improve PHR for standard NaI(Tl) crystal coupling
• Industrialization in progress
