Technical data<br />
<strong>Petrick</strong><br />
1. Geometry: according assembly drawing<br />
2. Type of operating: DC<br />
3. Max. operating voltage: max. 50 kV (but just max. approvable voltage of tube)<br />
4. Long-term capacity rating: depending on type of tube<br />
5. Max. housing temperature: 55°C<br />
6. Leakage radiation: < 2,0 µSv/h at 50mm (50kV, 1000µA)<br />
7. Weight: 3.000 g<br />
Emitter housing:<br />
<strong>GmbH</strong><br />
The X-ray tube assembly made of brass is used as protection housing for small fixed-anode X-ray<br />
tubes from <strong>Petrick</strong> <strong>GmbH</strong> and is completely free of lead-parts.<br />
To avoid overheating of the emitter, a temperature limiter is integrated, which is daisy-chained to the<br />
cathode heating, and it is equipped with a water cooling system.<br />
When achieving max. housing temperature, the temperature limiter turns off the heating of the tube.<br />
Applied insulating materials allow an anode voltage of up to 50 kV DC.<br />
A diaphragm system for compensation of oil extension protects the emitter against flashovers in any<br />
position, because no air bubble is located inside.<br />
Applied insulating oil is specially prepared und filled in under vacuum.<br />
Applicable X-ray tubes:<br />
Tubes with various focal spots, different anode materials and different radiation emission-windows<br />
(100µ und 200µ).<br />
Tube heating:<br />
Tube heating is connected by a 4-pole female connector.<br />
If a grid-controlled tube is applied and shall work with grid control, the joint between black and brown<br />
wire of the provided heating-cable has to be ripped and the necessary grid voltage to be supplied<br />
between black (-) and brown (+) wire. The tube never has to be operated with open grid connection.<br />
Heating data depend on the applied type of tube.<br />
High voltage connection:<br />
High voltage connection results from a high voltage-cable with UHF-plug 5/8-24 UNEF.<br />
Necessarily the connection has to be protected against impurity and humidity by the protection cap,<br />
which is included in delivery. High voltage-cable has to be cleaned if necessary and the dry surface to<br />
be fine coated with Silicone Paste P4 (available from us) before installation.<br />
HV-cables and heating-cables in customized length as well as hose-connection elements for watercooling<br />
are optional available.<br />
