450kV Pulser System, Flash X-Ray (FXR) System

The 450kV pulser belongs to a family of four Flash X-ray systems rated at 150kV, 300kV, 450kV, and 1MV. These systems provide successively greater penetration and are capable of operating at larger film-to source distances (FTSD).

The Model 43734A Flash X-ray System provides a 25nanosecond “burst” of 450 kV X-rays. As shown in the penetration curve on the next page, it will give radiographs through 0.7 inches (18 milimeters) of steel at 8 feet (2.5 meters) FTSD (film-tosource distance), or a shadowgraph at FTSDs up to 30 feet (9 meters). The system may be operated with the flash X-ray tube in the pulser (basic system configuration), in a remote tubehead configuration (option 032), or with X-ray tubes in two remote tubeheads (option 35). In the dual configuration (option 035), both tubes are fired simultaneously by the same pulser and can be used to obtain orthogonal radiographs of rapidly moving objects. The resulting radiographs enable accurate position location of the object under study.

ACCESSORIES
Gas regulators

All hardware required for system operation is furnished. This includes the control equipment, housed in a 6 foot (1.8-meter) cabinet, the X-ray generator, and a 30 foot (9meter) interconnecting cable bundle input. The Model 43734A system comes standard with all hardware required for operation, including the X-ray tube and a Model 43210A X-ray Controller (XCON), which provides both a delayed trigger for the X-ray pulser and a pulsed event timer to monitor the actual firing time of the pulser. The XCON provides a firing time delay variable from zero to 1000 milliseconds in 100nanosecond increments and monitors the actual pulser firing time with 10 nanosecond accuracy. Delay time setting and pulsed event time monitoring can be accomplished with the user’s PC via an Ethernet connection. Customer-furnished items are limited to regulated dry air and AC power (110 VAC, 60 Hertz). Up to three additional 450 kV X-ray generators (option 001) share the same control cabinet and power supply to minimize cost and floor space. Option 008 permits operation at a 220 Volts Alternating Current (VAC), 50-60 Hertz (Hz) line voltage.
