RF activities on cavities and turn key accelerator systems at ACCEL

Abstract

Beside the pure manufacture of normal and superconducting cavities ACCEL Instruments has continuously expanded its RF activities for worldwide customers in research and industry. Our scope includes feasibility studies on special and large scale cavity applications, review and optimisation especially on SRF modules as well as the supply of complete accelerator linacs and systems including control systems and rf supply. These projects are performed in tight co operation with the worldwide leading experts, universities, and research institutes, respectively. Besides various other activities, which will be described in more detail, the most recent test results of the superconducting TESLA Cavities will be presented. Further the production of the PEP II style cavities (476 MHz) will be described as well as the status of the fabrication of two 53 MHz copper cavities for BNL's National Synchrotron Light Source. The recent project of the 500 MHz Booster RF system for the Canadian Light Source will be introduced

Design modification and high-power tests of the 500 MHz normal-conducting 5-cell cavities for HEPS

“…Both 5-cell and 7-cell 500 MHz copper cavities of PETRA-type, widely used at various accelerator facilities [3][4][5][6][7][8], were carefully investigated, focusing on the cavity voltage, power rating, higher order modes and flexibilities. The 5-cell cavity was finally chosen due to its less severe higher order modes during the bunch charge accumulation stage at 6 GeV [9].…”
