Dear Carlos,

I can only give you feedback on the HyDs as we are using them on our SP5s.
You have to be more careful as on normal PMTs as the HyDs should have as few overloads as possible. Even though they have a protection against it, they are quite vulnerable.
Other than that they should be also quite reliable.
However, so far all of our 4 HyDs had to be exchanged at least once a year (in warranty) due to functional problems ( "comets" on the image), which should be solved on the new HyDs delivered more recently. So far we do not have any experience with GAsP-detectors...

I hope that helps,
Oliver

Hi, good morning.



Just a quick question, please, although it may be difficult to answer yet.
I've been said that GaAsP and/or HyD detectors might have shorter lifetimes
than conventional PMTs, so that they might even be considered fungible
materials. I am assuming a proper use of that detectors.



Is this true or just a rumour?



Thank you very much in advance for your help.

Regards,
