Coaxial Power Coupler Development at Argonne National Laboratory | |
|
||
| A series of coaxial rf power couplers with increasingly stringent demands on power handling, reliability and flexibilty of operations has been developed over the past decade at ANL. Intended for use in new and upcoming high-power SRF-based cavity linacs, these couplers span a range of physical sizes from 40-80 mm, frequencies from 72 MHz to 1.4 GHz, and cw power handling requirements from a few kiloWatts up to 20 kW thus far. Most of these also incorporate the capability to adjust the coupler axially in order to optimize the Qext due to effects of, for example, beam loading and multipacting. Several particular issues of mechanical, thermal and electromagnetic design, many uncovered through extensive experimental testing, are discussed. | ||
