News from Louisiana State University, Center for Advanced Microstructures and Devices

Lorraine Marceau-Day

The Center for Advanced Microstructures and Devices (CAMD) is pleased to host the 2005 Synchrotron Radiation Instrumentation (SRI) Conference. Perhaps we could put together a poster session on radiation protection for synchrotron rings. I know we have the biannual International Radiation Protection at Synchrotron Facilities (last held in Japan), but this might be another opportunity to get together.

Please note that the deadline for abstract submission is very soon--July 1--but it is not impossible to write an abstract in 30 minutes. Hope that at least some of you will consider submitting a poster. Further information is provided below.

Notice of Deadline

The deadline for abstract submission, July 1, for the US Synchrotron Radiation Instrumentation (SRI 2005) Conference at Baton Rouge, Louisiana (September 21-23, 2005) is approaching. Please visit the SRI-2005 website to submit an abstract and register for the conference. We hope to see you in Baton Rouge next September.

Detector Workshop

The most recent comprehensive workshop in the U.S. on synchrotron radiation (SR) detectors occurred a half decade ago. The consensus of the last U.S. workshop was that a clear gulf existed between the capabilities of modern synchrotrons to deliver high photon fluxes and the capabilities of detectors to measure the resulting photon, electron, or ion signals. During the last half decade, the world community, and especially the European community, has aggressively pursued detector research as a mechanism to enhance synchrotron capabilities and enable new research opportunities.

Objectives:

• To assess recent detector developments, both in the U.S. and abroad, in order to identify detector research opportunities that would enhance research capabilities at U.S. SR sources.
• To examine detector technologies, both short-term and long-term, and suggest a strategy to insure that the U.S. researchers are competitive, and remain so, in SR-based science.
• To acquaint young scientists with the present state-of-the-art in detector research and to convey exciting possibilities for the future.
• To document the conclusions of the workshop as an aid to future planning.

The proposal for the workshop will be submitted to the National Science Foundation (NSF) in the near future. Several international speakers are planned to be invited to the workshop.

Date: September 19 (Monday)--September 20 (Tuesday)
Place: Baton Rouge Marriott Hotel
Chairperson: Sol M. Gruner (Cornell University)
Workshop Committee Members: John Arthur (Stanford University), Dennis Mills (Advanced Photon Source [APS]), John D Scott (CAMD), Edwin Westbrook (Lawrence Berkeley National Lab [LBNL]), Peter Siddons (Brookhaven National Lab [BNL]), Howard Padmore (LBNL), Al Thompson (LBNL), Ralf Wehlitz (SRC).

Electron Beam Size Measurements Workshop

The assessment and optimization of electron beam size in synchrotron light sources continues to be highly relevant to the successful exploitation of the source. As sources of higher brightness have been developed, the accurate measurements of the source electron beam size, particularly in the vertical direction, has provided essential input to the optimization. The limitations of optical-based techniques have been used: pinhole optics, fresnel-based systems, interferometry, etc. Such techniques have much common ground between the accelerator and synchrotron light instrumentation communities.

Objectives:

• To review the present status of techniques used for measuring electron beam source size in bending magnets and insertion devices
• To consider new ideas for measurement of source size applicable to new sources of extremely high brightness
• To encourage exchange of ideas between the synchrotron light accelerator and instrumentation communities
• To document the workshop conclusions for the general benefit of the wider community.

Date: September 20 (Tuesday) afternoon (half a day)
Place: Baton Rouge Marriott Hotel
Chairperson: Victor P. Suller (CAMD/Daresbury)
Workshop Committee Members: W. Jeff Corbett (SLAC/SSRL), Misha Fedurin (CAMD)

SRI 2005 Conference Schedule

SRI 2005 conference will feature oral and poster sessions on synchrotron-related topics, workshops, a tour of CAMD synchrotron facility, and a Cajun-style banquet at a Louisiana-style plantation. Vendor exhibits are scheduled on Wednesday and Thursday. For the full schedule, please visit the website.
