Page 4: Source Setup
Source Setup Mechanical The shielded MAGNUM tube assembly may be mounted with the exit collimator facing any direction. Care should be taken not to strain the high voltage wires. Minimum high voltage wire bend radius is 1.25 inches. The high voltage power supply has three threaded holes on both sides of the metal case. These holes may be used for mounting (see Drawing 1). Cooling The MAGNUM tube does not require forced convection or liquid cooling. The tube should be operated in an environment that allows free convection or conduction to secondary parts. Please refer to page 2 of this manual for ambient and storage temperature specifications. The maximum ambient temperature, as measured at the surface of the power supply enclosure, is +10°C. The maximum operating anode shield temperature is 100 degrees Celsius (see Figure 2). Electrical Output power below 4W: Moxtek recommends using the 2-pin optional secondary cable (ASM00364) while operating the 50kV Magnum Tube (Figure 4). The pin assignment is shown in Drawing 1 and in Table 1. Output power above 4W: 2-pin secondary cable is required for tube output and stability (Figure 4). Attach the 2 pin secondary power cable to the backside of the high voltage power supply case. Refer to Figure 3 and Table 1 for pin identification and electrical specifications. Attach the 2 bare wire leads to a 6 to 10VDC power supply or to a Moxtek FTC-200 x-ray tube controller. The high voltage power supply also has a 10 pin IDC connector. This connector is used to power, control, and monitor the x-ray tube (Figure 6). A 10 lead ribbon cable is available from Moxtek (Figure 3). This ribbon cable has a 10 pin IDC connector on one side that connects to the high voltage power supply and a DB9 connector on the other end that connects to the Moxtek FTC-200 controller. The pin assignment for the 10 pin IDC is shown in Drawing 1 and the pin-out for the DB9 connector is shown in Table 1. Safety To assure safe tube operation, a 5 volt TTL signal is sent to the power supply to enable x-ray generation. Moxtek recommends the use of a safety interlock switch when operating the MAGNUM x-ray tube. Connect the high voltage enable pin (see Table 1) to the customer supplied safety interlock switch.

Page 5: Operating Conditions
PROPERLY SHIELDED ENCLOSURES. It is the responsibility of the operator to ensure that all applicable safety precautions are taken and observed. WARNING: MAGNUM X-ray tubes operate at high voltages. Refer to tube handling instructions on page 3. Precautions should be taken to protect the operator while applying high voltages to avoid serious injury or death. Operating a MAGNUM Source without a Moxtek FTC-200 Controller The high voltage power supply uses DC voltages and signals to operate the tube. To operate the tube without using a Moxtek FTC- 200 controller, refer to Drawing 1 for the 10 pin high voltage power supply connector pinouts. Operating the MAGNUM X-ray Source with a Moxtek FTC-200 Controller The FTC-200 controller is designed to power, monitor, and control the MAGNUM x-ray tube. This controller contains all of the necessary electronics to operate the high voltage power supply. The FTC-200 controller provides input power to the high voltage power supply. The FTC-200 controls the high voltage and emission current settings on the x-ray tube. The FTC-200 controller includes built-in meters for convenient monitoring and display of the high voltage and emission current. Refer to the FTC-200 Operation Manual for operating instructions. 452 West 1260 North / Orem, UT 84057 TUB-MAN-1001, Rev A Phone 801.225.0930 / Fax 801.221.1121...
