Several high energy physics programs include technologies to build a TeV-scale, electron-positron, linear collider that would use normal conducting X-band (11.4 GHz) microwave power. However, the Next Generation Linear Collider (NLC) will be ten times the size of present-generation linear accelerators. Therefore, low cost, highly reliable, high voltage, high power supplies, with very high regulation and stability, will be required. This project will develop the high voltage designs needed to build a switching power supply that meets these specifications, and is capable of providing approximately 80 kW at 80kV (with efficiency over 95% and predicted reliability of over 100,000 hours). Another major objective will be to reduce the manufacturing cost of these supplies by a factor of five or more in volume production. During Phase I, a prototype power supply will be developed and evaluated for performance. This prototype will provide the basis for development of affordable, cost effective switching power supplies in Phase II and the subsequent production of the thousands of units needed for NLC.
Commercial Applications and Other Benefits as described by the awardee: The high voltage, switching power supply market is growing 24% annually worldwide. This power supply design should also directly translate into government and commercial pulsed-power applications such as, radar transmitters, broadcast power supplies, ion implantation, thin film deposition, and flat panel display manufacturing.
