50-75W Industrial X-Ray Generators

The uX Series is the result of Spellman’s exceptional high voltage packaging and surface mount fabrication techniques coupled with proprietary encapsulation technology producing this ultra-compact X-Ray generator module. The uX powers grounded cathode X-Ray tubes from a variety of well-known manufacturers, featuring a 0 to 50kV/65kV high voltage output @ 2mA limited to 50, 65 or 75 Watts. The uX uses closed loop .lament control circuitry providing highly regulated beam current. The low noise dc .lament supply operates between 0.3 and 3.5 amps. Offering tight regulation, high stability and low ripple, the uX provides users local and remote analog control to set beam voltage, emission current and .lament current limit. USB, RS-232 and Ethernet interface is standard. 

Typical applications:

Powering grounded cathode X-Ray tubes from Kevex, Oxford, RTW, Superior, Varian and Trufocus.

X-Ray Tubes

 The uX powers grounded cathode X-Ray tubes from manufacturers such as Varian Medical Systems, Petrick GmbH and others.

cathode X-Ray tubes

Digital Interface

 The uX features a standard USB, RS-232 and Ethernet digital interface. Utilizing these standard digital interfaces can dramatically simplify power supply interfacing requirements saving the user both time and money, while enhancing functionality and overall capabiity. Spellman provides a GUI with the uX that allows the customer to both customize operational features of the uX while also providing basic power supply operational features. Details of the uX’s digital interface capability are described in detail in the uX manual.

Grid Bias Option (GB):

Plug-n-Play compatibility for Oxford’s Apogee X-Ray Tube Spellman’s Grid Bias Option for the uX Series is specifically designed for popular commercially available grid bias X-Ray tubes. The Grid Bias voltage is developed via the use of separate integrated high frequency switching circuit, providing maximum flexibility and control. The Grid Bias output is a voltage regulated, current compliant topology ideally suited for Wehnelt electrode applications. Arc and short circuit protection of the Grid Bias output prevents any damage due to transient events or installation errors.

 

Tracking Mode Operation

Functioning in tracking mode the voltage monitor (0-10Vdc = 0 to 50kV) of the main high voltage output is internally connected to the Grid Bias programming input (0-10Vdc = 0 to -300Vdc of Grid Bias). Connected in this manner the Grid Bias output will track in a linearly proportional fashion the setting of the main kV output. A multiturn potentiometer limits the maximum magnitude of Grid Bias output applied to the X-Ray tube, providing unparalleled flexibility. The output of the Grid Bias option is provided via an auxiliary two position Phoenix Contact terminal block, the mating connecter is provided.
