Upgraded front ends for SLS 2.0 with next-generation high-power diaphragms and slits

Area of Science:

• Synchrotron Radiation
• Particle Accelerators
• Experimental Physics

Background:

• The Swiss Light Source (SLS) is undergoing a major upgrade to SLS 2.0.
• This upgrade significantly increases synchrotron beam power and brightness (up to 40x).
• New safety regulations and space constraints also necessitate front-end modifications.

Purpose of the Study:

• To detail the comprehensive updates required for the 18 user front ends at SLS 2.0.
• To address challenges posed by increased beam power, altered source points, and reduced space.
• To implement innovative solutions for cooling, stability, and compact design in new front-end components.

Main Methods:

• Refurbishment and upgrading of existing front-end components for safety compliance.
• Complete redesign and rebuilding of components for tailoring the new synchrotron beam.
• Development and integration of advanced cooling systems for high-power beam management.
• Engineering for enhanced mechanical stability and compact footprints.

Main Results:

• Successful adaptation of user front ends to accommodate the enhanced SLS 2.0 synchrotron beam.
• Implementation of robust cooling solutions to manage high thermal loads.
• Achievement of required mechanical stability and compact designs for new components.
• Ensured safety compliance and operational readiness for the upgraded facility.

Conclusions:

• The comprehensive front-end upgrades are essential for the successful operation of SLS 2.0.
• Innovative engineering solutions have been implemented to meet the demands of the upgraded synchrotron beam.
• The enhanced front ends will support advanced scientific research with improved beam properties and reliability.
