The world’s first experimental observation and achievement of ‘optical stochastic cooling’ (i.e., relativistic charged particles cooled via feedback from their own optical radiation) in the IOTA storage ring at Fermilab, USA was reported in Nature, August 11, 2022. Recapturing that achievement, I will report on further progress in optical stochastic cooling in IOTA to date. The method has...

AWAKE studies and develops a plasma wakefield accelerator driven by a long proton bunch to produce high-energy electrons for application to particle physics at CERN. It relies on the self-modulation of a cm-long, 400GeV proton bunch to reach ~1GV/m accelerating fields. It is also a platform to study beam-plasma interactions. I will introduce the project and experiment. I will show...

The CERN accelerator complex provides beams for a highly diverse, world class fixed-target research programme, which complements its flag-ship collider physics programme. At the same time, it enables an extensive and highly versatile test beam and irradiation programme, which is essential for the design, prototyping and construction of future physics experiments and new accelerator...

With Net Zero targets and climate change on the minds of policy makers, technology vendors, utility providers and the general public, challenges have never been greater in the energy sector. It is clear from the direction of travel over the last decade that nuclear will play a part in this energy mix, to what degree is largely undecided. What is apparent is the need for new solutions to ensure...

Radioactive ion beam facilities employ accelerated particles to produce exotic isotopes for experiments in fields ranging from nuclear, atomic and solid-state physics, to biophysics and medicine. A key subset of these facilities is the thick target Isotope Separator Online or ISOL type, where the irradiated material is thick enough to stop and thermalise the nuclear reaction products prior to...

The future high repetition rate upgrade of the EuXFEL assumes the implementation of a continuous wave (CW) electron source. A CW photoinjector based on the 1.3 GHz SRF gun cavity is the preferred option for EuXFEL. Recently, we demonstrated the possibility of achieving a peak axial electric field of 55 MV/m with a copper photocathode installed. Further steps include advanced metal photocathode...

The talk will provide a description of the secondary beamlines at CERN. More specifically, it will address the operational principles and the available beam parameters, as well as highlights of the exciting physics that takes place at these unique facilities at CERN. The talk will also cover HiRadMat - the high-energy, single-pulse facility for material tests at CERN.

A 217 MHz very-high-frequency gun operating in CW mode is being developed at Tsinghua University, which will be served as the beam source of the high repetition XFEL facilities and high repetition MeV UED. The cavity profile has been optimized to minimize input power, peak surface electric field, and peak wall power density. The profile optimization also takes into account the suppression of...
