Fast X-ray detection

X-ray detectors:
custom sensors for x-rays,
here based on nanosecond response
avalanche photodiodes (APD's).

2 ns/div, 50mV/division
These APD detectors
have fast response times.

The square centimeter size
APD is placed in a beam of
x-rays to either count single or multiple photons.

Because these APD silicon
detectors are fairly
thick, they are efficient
at stopping and counting
x-rays.

We have automated
the test process for APD sensors.
