5.8 Danger due to high voltage
The radio frequency (RF) generator changes low frequency mains
energy into radio frequency electrical energy (13.56 MHz). It
serves to excite the laser medium.
Radio frequency voltages of up to 10,000 V can arise during the
operation of the generator. The ignition voltages are about twice as
high.
Dangers caused by high voltage can arise in the following com-
ponents:
•
Adaptive network in the resonator.
•
Auxiliary ignition for the discharge path.
•
Electrodes along the discharge path (shielded).
•
Switch cabinet of the RF generator.
Safety warning signs for high voltage are attached at the following
points:
•
Discharge path at the resonator.
•
X51 terminal box in front of the telescope cover.
•
Auxiliary ignition in front of the telescope cover.
•
Switch cabinet of the RF generator.
•
Main power supply and main switch at the switch cabinet.
Safety warning signs for high voltage
•
Work on the RF generator may only be carried out by trained
specialists from the laser manufacturer, or by appropriately
trained employees of the user.
•
The instruction manual for the high-frequency generator must
be observed for all work undertaken.
•
Safety locks have been installed on the doors of the RF
generator. The energy supply is interrupted automatically if the
doors are opened.
•
Warning signs have been applied to parts carrying high
voltages.
