Development of a Fast X-ray Shutter System. Final Technical Report

The objective of the project was to develop a fast shutter mechanism to allow separation of a single pulse of x-rays out of the given time structure of the APS. Technological challenges in developing this device range from engineering of ultra high strength alloys, mechanical shape development for optimal strength, coupling such materials to motorized shafts, magnetic suspension of high velocity rotors in combination with phase pick up and excursion monitoring, resonance control and jitter-free electronics. The pulse selector was delivered, integrated into the x-ray diffraction environment and tested. The researchers developed an acoustic delay line as protection against air inrushes and associated failure of the rotor and thin diamond windows for maximum x-ray transparency. Design goals were reached or exceeded and practical experience with the device began in March 2000
