Description

In the framework of the series of the european workshops on photocathodes for particle accelerator applications (previousy EWPAA), the next event will be held in France, near Paris, following the 5th edition hosted at HZDR in Dresden in 2024.

Organized by CNRS/IN2P3 via LPSC and IJCLab, the Photocathodes for Accelerator Science in Europe workshop (PhASE26) will be hosted by Irène Joliot Curie Laboratory (IJCLab) in Orsay, September 21-23, 2026. This meeting brings together experts in the field of photocathode electron sources dedicated to particle accelerators aiming to share knowledge and latest progress in this field, critical of future accelerators.

The event will propose about 40 oral presentations, organized in 8 sessions, as well as a poster session (format A0, portrait) and visits of IJCLab’s infrastructures.

The sessions will cover:

  • overview of photocathode research
  • accelerator applications of photocathodes
  • photocathode related studies and novel concepts
  • metallic photocathodes
  • semiconductor photocathodes
  • polarized photocathodes
  • theory of photocathodes
  • characterization techniques.

 

A social event is planned with a diner cruise on the Seine river, allowing sight seeing of beautiful Paris monuments (Notre Dame, Eiffel tower, Louvre).

Proceedings will be published (no peer-review) based on one-page summary provided by each speaker when the workshop starts.

If you need a visa to attend this event, please contact the organizers.

We hope to see you in Orsay !
