3rd Workshop on Low Emittance Lattice Design - LEL 2022

26 Jun 2022, 19:30 → 29 Jun 2022, 16:00 Europe/Madrid

Maxwell Auditorium (ALBA)

Gabriele Benedetti

The 3rd Workshop on Low Emittance Lattice Design - LEL 2022 will be held from the 26th to the 29th of June 2022, hosted by the ALBA Laboratory, Cerdanyola del Vallès (Barcelona), Spain.

The workshop is organised by ALBA and supported by the iFAST project. It is the third one in a series of workshops on this topic.

The goal of this series of LEL workshops is to bring together experts from the scientific community working on low emittance lattice designs for high brightness light sources and colliders.

The workshop will focus on the following topics:
- LEL Design concepts
- LEL design Tools / non-linear optimisation Tools / analysis Tools
- LEL Error sensitivity / Alignment strategies / Correction schemes
- LEL Collective effects
- LEL Injection / design of injector chain

The 3rd LEL Design workshop is a face-to-face meeting, no option to attend the sessions on-line.

This project has received funding from the European Union’s Horizon 2020 Research and Innovation programme under Grant Agreement No 101004730.
