Emitter housing:
The X-ray emitter made of brass is used as protection housing for small fixed-anode X-ray tubes from
Petrick GmbH and is completely free of lead-parts.
To avoid overheating of the emitter, a temperature limiter is integrated, which is daisy-chained to the
cathode heating.
When achieving max. housing temperature, the temperature limiter turns off the heating of the tube.
Applied insulating materials allow an anode voltage of 60 kV DC.
Adiaphragm system for compensation of oil extension protects the emitter against flashovers in any
position, because no air bubble is located inside.
Applied insulating oil is specially prepared und filled in under vacuum.
Applicable X-ray tubes:
Tubes with various focal spots, different anode materials and different radiation emission-windows
(100µ und 200µ).
Tube heating:
Tube heating is connected by a 4-pole female connector.
If tube has grid control and shall work with, the joint between black and brown wire of the provided
heating-cable has to be ripped and the necessary grid voltage to be supplied between black (-) and
brown (+) wire. The tube never has to be operated with open grid connection.
Heating data depend on the applied type of tube.
High voltage connection:
High voltage connection results from an optional available high voltage-cable with UHF-plug 5/8-24
UNEF screwing.
Necessarily the connection has to be protected against impurity and humidity by the protection cap,
which is included in delivery. High voltage-cable has to be cleaned if necessary and the dry surface to
be fine coated with Silicone Paste P4 (available from us) before installation.
HV-cables and heating-cables are optional available in customized length.
