0.080 MWCFF24 X-ray tube assembly "Vari-Aqua" with water-cooling and Be-window tube Technical data Petrick 1. Geometry: according assembly drawing 2. Type of operating: DC 3. Max. operating voltage: max. 50 kV (but just max. approvable voltage of tube) 4. Long-term capacity rating: depending on type of tube 5. Max. housing temperature: 55°C 6. Leakage radiation: < 2,0 µSv/h at 50mm (50kV, 1000µA) 7. Weight: 3.000 g Emitter housing: GmbH The X-ray tube assembly 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, and it is equipped with a water cooling system. When achieving max. housing temperature, the temperature limiter turns off the heating of the tube. Applied insulating materials allow an anode voltage of up to 50 kV DC. A diaphragm 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 a grid-controlled tube is applied and shall work with grid control, 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 a high voltage-cable with UHF-plug 5/8-24 UNEF. 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 in customized length as well as hose-connection elements for watercooling are optional available. Page 2 from 6
