Faster PMTs ?

• 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

5
Super bi-alkali photocathode
QE ()

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