Special design issues of low emittance electron storage rings

PSI is planning for an upgrade of the Swiss Light Source (SLS) storage ring (project “SLS 2.0”), and already submitted a proposal to the Swiss National Science Foundation (SNF) early 2018. CANDLE SRI pursues design of a new light source for Armenia as one of its most promising projects. PSI and CANDLE successfully collaborated since 2007 in various ways, including shared work packages, mutual visits of scientist and organization of joint workshops.

Our joint proposal addresses special problems of low emittance storage rings, which are both relevant for the SLS upgrade and for the future light source at CANDLE. It has several benefits with regard to scientific progress, support of young scientists and launching further collaborations based on third party funding:

  • Collaboration on particular problems of low emittance rings, for example on vacuum chamber impedances, where CANDLE SRI traditionally has a high level of competence, and PSI has a strong interest to strengthen confidence in predictions.
  • Establish a collaborative platform for involvement of young talented scientists from CANDLE in joint R&D within the SLS upgrade program. Hands on experience and face to face communication with leading scientists will give opportunities for the Armenian side to acquire a new working culture, to experience cultural exchange and to pursue further career development.
  • Dissemination of latest achievements in low emittance lattice design: in order to be competitive it is extremely important for the CANDLE project to stay attached to state-of-the-art research and technology in the field. In this context dedicated seminars and/or lectures by Swiss experts will promote generation of new and further development of existing ideas for the CANDLE project.
  • Career opportunities for Armenian scientists: PSI is a leading accelerator center and thus young scientists may gain experience with latest technology and software as well as with working in an international environment. This will enable successful applications for post-doc and other positions in laboratories all over the world, including PSI itself.
  • Establish partnership contacts with respective divisions and persons at PSI and CANDLE in order to jointly apply for international funding programs (IJRP, ISTC etc.) This benefit will also constitute the project sustainability factor and may pave the road for further collaboration after the end of funded project.

We strongly believe that this project will be beneficial for both sides considering the accumulated expertise of PSI with design, exploitation and upgrade of the SLS, and the high level of beam dynamics knowledge at CANDLE SRI.
