resolution of 0.3 mm. The equipment can take sequences of up to 100 frames at 150 kVp and 50 frames at 350 kVp. The 150 kVp pulser can be used with a remote tubehead. The image intensifier is equipped with a Varian caessium iodide input phosphor screen of 210
mm diameter which gives rapid erasure of former images. The system can be fitted with a z o o m . The camera is a Photo-Sonics 16 mm IW machine with pin register rated to 1000 frames s-1 . (Fig.8). Field Emission (UK), 1 Wallace Way, Hitchin SG4 0SE, UK

X - r a d i o g r a p h y speeds up Field Emission (UK) has introduced an American high-speed x-raycin~ system onto the British Market. The system was recently exhibited for the first time at the international high-speed photography congress. It repeats x-ray flash exposures of 3 0 - 5 0 ns for each frame of film to give frame rates of up to 1 0 0 0 s l . It uses an x-ray image intensifier to produce pictures for filming. There are four basic units: an electronic pulse generator, a flash x-ray generator, an image intensifier and a high-speed camera. The electronic pulse generator comprises the high-voltage power supply and control as well as synchronization and trigger circuitry. The flash x-ray generator includes a Marx-surge highvoltage pulser and a cold-cathode diode field-emission x-ray tube at 350 or 150 kVp. The 350 kVp can penetrate 50 mm ofaluminium. The makers claima
