Auxiliary x-ray alarm
To detect x-rays that are causing process changes, a second detector can
be placed outside of the radiation beam of the primary detector. The second
detector only monitors x-ray interference, and has a frequency output that
wires to the auxiliary input of the primary detector.
The primary detector's programming triggers the x-ray alarm when the
counts of the secondary detector are above a threshold.
Call VEGA for more information.
