Ken,
If it is a thinner window than you had before, you should see the effect mostly for the softest x-rays:
The ratio New counts/ old counts would be highest for the softest x-rays. The ratio would progressively decrease as x-ray energy increased.

Subject: Re: [PROBEUSERS] Detector Window question
My thoughts too. I checked and they are. Maybe I got a super thin window!

Yes, sounds big to me too. Are the slits in the same position ?

Hi all - we just changed the detector window on one of our argon detectors and are seeing somewhere around 20-25% more counts using the new window. This seems like a huge increase. While I would expect some change, I would expect the change to be in the range of a couple percent. Has anyone else seen this?
Thanks!
