3.6 High Voltage Generator
DANGER!
DANGER OF DEATH BY ELECTROCUTION:
Any tasks on the electrical equipment (high voltage generator, electronics...) must b e
performed by certified and qualified personnel only.
All energized parts are accessible with specific tools only. Any service tasks must be
performed only when the instrument is unplugged and by qualified personnel only. All
conductive parts are usually isolated from the energized parts and are grounded to each
other.
A safety beacon indicates that the X-Ray generator is in operation.
3.7 Protection Enclosure and X-Ray Tubeshield
WARNING!
WARNING IONIZING RADIATION:
X-Ray is ionizing radiation which has effects on living tissue and on the organism.
While the X-Ray generator is in operation and the shutter is opened, no access inside
the enclosure is permitted.
Both the enclosure and the tubeshield of the ARL X-Ray diffractometer fulfill the function of a
protection shielding against the ionizing radiation. The enclosure surrounds the instrument
and helps to attenuate the diffused radiation emitted by the X-Ray tube. The X-Ray tube is
mounted in a tubeshield which is the most important part of the X -Ray protection. The optics
and collimation enable forming the X-Ray beam aperture to a directional beam. Never use
the instrument with a damaged enclosure, tubeshield or optics line!
Control circuits are designed to monitor the state of the shutter (opened or closed) and adjust
them accordingly while the generator is running.
Safety interlocks located on the enclosure's door enable to lock the door during the emission
of X-Rays in the analysis area.
