Introduction
Fourth-generation storage rings based on multibend achromat (MBA) lattices have, over the past 5 years, completely changed the landscape of synchrotron light sources worldwide. In fact, three such new sources are already in operation and many more are in design or construction in Europe, the Americas and Asia, all profiting by the quantum jump in brightness and coherence provided by their ultralow emittance electron beams.
Even though harmonic RF systems have been successfully in use at third generation sources since many years, they were often added to those sources as part of upgrade programs while they are part of the baseline design on most fourth generation sources, particularly in the intermediate energy range of a few GeV where IBS is most severe. For future light sources aiming to achieve even lower emittances than the present suite of existing and planned sources, good control of the bunch length will be even more critical and one may envisage the need to achieve considerably larger lengthening ratios than those achieved today (which vary from 2 to 5).
To attain the desired bunch lengthening requires overcoming a particular set of technical challenges and an accurate knowledge and evaluation of the associated Physics. To decide which of the various available implementations, both actual and proposed, of a harmonic RF system is most suitable for a given storage ring is also a challenge in itself. Analysis to this end is ongoing as part of the design efforts of various projects and is also relevant for the already running fourth generation rings.
HarmonLIP 2022 is the first workshop organized within the HarmonLIP Leaps Leaps Internal Project and aims to foster information exchange and joint research efforts amongst the LEAPS members for the further development of harmonic cavity/bunch lengthening systems for present and future ultralow emittance storage rings.
The Workshop will be held in hybrid format allowing for both on-site and remote presentations and participation.
The workshop will be divided into three consecutive plenary sessions:
- Review of ongoing projects
- Beam dynamics
- Engineering and diagnostics
