HarmonLIP 2024

Mar 18, 2024, 6:00 PM → Mar 20, 2024, 2:00 PM Europe/Paris

Auditorium (ESRF, Grenoble)

HarmonLIP 2024 is the second workshop organized within the HarmonLIP 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 ultra-low emittance storage rings.

The workshop will be held in hybrid format allowing for both on-site and remote presentations and participation. It will be divided into three consecutive plenary sessions:

1. Project Overview
2. Beam Dynamics
3. Engineering R&D

1 Welcome and Introduction

Speaker: Jorn Jacob

2 Double RF System (fundamental + harmonic) for SOLEIL-II (REMOTE)

Synchrotron SOLEIL has now entered a new major upgrade phase with the
SOLEIL-II project, which aims at designing and operating a 4th generation
light source. The SOLEIL-II storage ring will rely on a double RF system
with fundamental and harmonic cavities, which will compensate the energy
loss per turn and provide long enough bunches to preserve the extremely low
emittance while insuring a suitable lifetime. A status of this RF system
study is reported in this presentation.
