Photocathode Physics for Photoinjectors

Dates: October 12–14, 2010

Hosted by Brookhaven National Laboratory

Motivation

Photoinjectors are a critical research area for modern accelerators, from ultra-high peak brightness machines to high-average current, storage-ring replacements to next-generation colliders. These devices rely on photocathodes to produce beams with precisely controlled temporal and spatial shapes, often with stringent requirements on emittance, temporal response and polarization. This 3-day workshop at Brookhaven National Laboratory (October 12-14, 2010) will explore the current state of the art in accelerator photocathodes, from both a theoretical and a materials science perspective, will establish directions for future research and opportunities for collaboration and form a repository for the latest information on photo cathode research.

Topics Include:

• Current status of photocathodes for accelerator applications
• Current fabrication methods
• Applications of modern materials science to the growth and analysis of cathodes
• Photoemission spectroscopy as a diagnostic of cathode performance
• Utilization of modern user facilities (eg. x-ray synchrotrons, electron microscopy)
• Photoemission theory
• Novel ideas in cathode development
• Discussion forum on future collaboration for cathode growth, analysis and testing

The organizers envision a workshop format that will allow plenty of time for discussion. There will be relatively few scheduled talks in each session, with most of the time allotted to short informal presentations and discussions. We will have visiting speakers from the major materials programs at BNL and elsewhere on hand for discussions of cathode materials science. Most attendees will not have scheduled presentations, but every attendee is encouraged to bring 3-slide mini-talks on topics of interest, both to explore new ideas and to stimulate discussion. We envision this workshop as the first in an ongoing series, and we expect to create a persistent knowledge repository on cathode development and performance which will be available to the community.
