Initial Inspection - MOXTEK MAGNUM X-ray Source Manual

Initial Inspection

When a MAGNUM tube is received, it should be unpacked and inspected as soon as possible. A standard MAGNUM tube is
packaged in a brass shield. This shield is connected to a high voltage power supply via two white high voltage wires and one
green ground wire (Figure 1). Inspect the high voltage power supply and the tube shield assembly for any damage that may have
occurred during shipping. If a tube has been damaged, please contact Moxek immediately. The serial number is located on the
high voltage power supply. Please do not touch the beryllium window. Do no pull on or bend the high voltage wires.

Handling
Care should be taken when handling the tube and the high voltage power supply. Lift the power supply and the tube with both
hands to avoid damaging the high voltage wires or potting material. Prevent the tube from striking any surface. Care must be taken
to not damage the beryllium window or high voltage wires.
