4.0 DESCRIPTION OF OPERATION
The block diagram below illustrates how the XRS3 functions. The following sequence of events takes place each
time the XRS3 is red:
1. User initiates operation of the machine.
2. The control section sends a signal to the converter section to begin oscillating.
3. Once oscillating, the converter section changes the 20 volts DC to 22Khz AC.
4. The transformer charges the High Voltage Capacitor to about 9000 volts.
5. The spark gap arcs after the High Voltage Capacitor reaches proper voltage.
6. The pulse detector signals the control block that the unit has pulsed.
7. As the High Voltage Switch is closed, a high voltage transient of approximately 270,000 volts and
25 nanoseconds in duration is applied across the x-ray tube generating x-rays.
The closing of the High Voltage Switch produces an audible pulsing sound. The XRS3 cannot produce x-rays
without the pulsing sound so it serves as an additional warning the XRS3 is functioning.
This unit generates X-rays through high voltage bombardment of a tungsten target. The XRS3 does not contain
radioactive materials . All the high voltage is contained within the aluminum canister and as long as the canister
is not punctured the operator is not exposed to dangerous voltages.
