The output signal is compatible with micro-electronic chips. The magic thing is that you can have a 120dB with very very low noise and dark current.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-24108584552669771492010-10-28T08:52:10.787+02:002010-10-28T08:52:10.787+02:00I think one of the potential advantages of MEMS pr...I think one of the potential advantages of MEMS processing is that it's wafer-scale, so it's supposed to be cheap. If PMTs are going to cost less than dollar a tube, it might be an interesting development. The only problem is to reduce their voltage level to a more acceptable in semiconductor industry.Vladimir Koifmanhttps://www.blogger.com/profile/01800020176563544699noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-44748879628522088412010-10-27T16:50:10.903+02:002010-10-27T16:50:10.903+02:00My guess is that there are no moving parts.

MEMS technology might be used for micro-channel fabrication where photo-multiplication can take place under large reverse voltages.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-54977826492948701392010-10-27T16:41:44.811+02:002010-10-27T16:41:44.811+02:00Hello all,

Kinda reminds me of that. Old is gold!.<br />(Technology) hybridization/amalgamation may hold the key for future..CCDs in CMOS for instance!Anonymousnoreply@blogger.com
