SESAME receives bunch by bunch electronics as a donation from Australian Synchrotron

09 March, 2020

The Australian Synchrotron (ANSTO) welcomed Nashat Sawai, a senior RF engineer from SESAME, following the donation of bunch by bunch feedback digital electronics to SESAME.

The donated instrumentation will enable SESAME to build and install a type of feedback system on storage ring that will improve the beam stability, consequently the quality of the emitted synchrotron light. The donated electronics are expected to arrive at SESAME within two months.

Prof Andrew Peele Director of the Australian Synchrotron said “he is pleased that SESAME could use the digital processing electronics, which were retired following an instrumentation upgrade at Clayton a few years ago”.

The mutual exchange of knowledge between synchrotron facilities and increasing the sustainability of technology are important outcomes,” as he said.

In addition to some hands-on training, Sawai was able to share information about the RF solid state amplifiers used at SESAME in storage ring and booster, a technology that the Australian Synchrotron is interested in using it.

The solid stat amplifiers increase the operational reliability as downtime on the amplifier system results in lost time for users,” said Sawai.

This visit was a result of previous communications between SESAME RF group and the Australian synchrotron team, it was managed by ANSTO accelerator instrumentation scientist Mark Atkinson, and Manager of Accelerator Physics and Operations Group Rohan Dowd, and Eugene Tan.

The desire for future collaboration has been expressed by both sides during and following the visit. The visit is hoped to be just a start of more future collaboration between both sides, as expressed by Darweesh Foudeh, leader of RF group and Maher Attal, technical director of SESAME.
