Synchrotron SIG Report 2011

During the past year the Synchrotron SIG has neither collected nor spent any funds.  The group sponsored 2 sessions and cosponsored 5 sessions at the 2011 meeting.   The Executive Committee selected Lauren Hatcher from the University of Bath (UK) as the SIG's Etter Student Lecturer.  At the 2011 SIG meeting, which was well attended, the members agreed to include the LCLS and similar sources within its purview.  Graeme Card from SSRL agreed to be a candidate for the SIG chair in the next election.

For the 2012 meeting the SIG proposes the following sessions (cosponsors thus):

Next Generation Sources, Theory and Practice (Two sessions) 

Chairs,  Marius Schmidt and Keith Moffat

Advanced Hardware and Applications

Chair John Rose

Extended Wavelength Crystallography 

Chairs  B.C. Wang and Bob Fischetti  (Biomac)

Radiation Damage and Strategies  

Chair  Steve Ginell  (Biomac)

Membrane Protein from Start to Finish  

Chair  Vadim Cherozov   (Biomac)

Complementary Methods  

Chair Michael Fodje   (Biomac, Can)


Note:  Results from the planning meeting may differ from the above.

Henry Bellamy, 2011 Synchrotron SIG Chair


Synchrotron SIG Report for 2010

In 2010, Henry Bellamy from CAMD was elected (by acclamation) the synchrotron SIG chair-elect for the 2010 Chicago meeting to become the 2011 chair at the New Orleans meeting. At the 2010 meeting in Chicago, the synchrotron SIG meeting occurred on July 26 with about 20 members present. Two agenda items were discussed. The first item was the identification of scientists for the 2011 synchrotron SIG chair-elect to become the synchrotron SIG chair for the 2012 Boston meeting. Craig Ogata from APS was proposed as a candidate. The second agenda item was the selection of potential synchrotron SIG sessions for the 2011 meeting in New Orleans. Three specific sessions were proposed. The first is  'Maximizing the Scientific Output from your Synchrotron Visit' with S. Ginell proposed as the chair. Steve will identify a co-chair.  The second proposed session topic is 'Fast Science' for which session chair(s) have yet to be identified.  The third session is "Science Enabled by NSLS II and the LCLS" for which chair(s) also have yet to be identified. The SR SIG will be co-sponsoring additional sessions including the Transactions Symposium.     


Overall the synchrotron SIG-related sessions in Chicago were well attended having more then 200 participants. The 'historical' talk given by G. Rosenbaum was timely with the Nobel prize lectures and the results from the LCLS experiment for which Mark Hunter (Arizona State University) received the student Etter award from the synchrotron community.


The SR SIG has not collected nor spent any money during 2010 and does not anticipate doing so in the remainder of the year.


Synchrotron SIG Report for 2009

In 2009, Marc Allaire from the National Synchrotron Light Source at Brookhaven National Laboratory was elected (by acclamation) the synchrotron SIG chair-elect for the 2009 Toronto meeting to become the 2010 chair at the Chicago meeting. At the 2009 meeting in Toronto, the synchrotron SIG meeting occurred on July 28 with about 30 members present. Three agenda items were discussed. The first item was the selection of potential synchrotron SIG sessions for the 2010 meeting in Chicago. Two specific sessions were proposed. The first one was a continuity of the successful 2009 'Instrumentation' session renamed to 'New Tools - New Lights'.  It was also suggested that a 'Radiation Damage' session would be timely in 2010. Additionally, multiple sessions to be co-sponsored with other SIGs were identified. It was noted that the first experimental acquisition of diffraction data from synchrotron radiation occurred in 1970 and we could highlight its 40th anniversary with a historical talk potentially given by G. Rosenbaum.


The second agenda item was the identification of scientists for the 2010 synchrotron SIG chair-elect to become the synchrotron SIG chair for the 2011 New Orleans meeting. Henry Bellamy from CAMD was proposed as a candidate for the new synchrotron SIG officer. As a third agenda item the members were exploring the idea that a new award could be created that would recognize the work of a scientist working at user facilities. Overall the synchrotron SIG-related sessions in Toronto were well attended having close to 200 participants. Jesse Smith from University of Ottawa was awarded the 2009 synchrotron SIG student Etter award.


During 2009 the SR SIG did not collect or spend any money. 





(With amendments ratified December 2006 December 2013)


I.          NAME  The name of this group shall be The SCIENTIFIC INTEREST GROUP on Light Sources (formerly) Synchrotron Radiation.


II.        PURPOSE  The purpose of this group of the American Crystallographic Association (hereafter ACA) is to further the advancement of all aspects of synchrotron x-ray research and to promote communication between persons interested in such techniques and results.



The constitution of this organization shall be consistent with the Constitution, By-laws, and Operating Rules of the ACA. In the event of conflict the Constitution, By-laws and Rules of the ACA shall prevail.


IV.       MEMBERSHIP  Membership in this Group is open to all members of the ACA on application to the Secretary-Treasurer of this SCIENTIFIC INTEREST GROUP and payment of the prescribed dues, if any.


V.        ORGANIZATION  The activities of this Group shall be administered by an Executive Committee of three officers elected by members of the Group.  The officers of the Executive Committee shall be Chair, Chair-Elect and Immediate Past Chair.  It shall be the duty of the Chair to arrange, in cooperation with the ACA Program Chair, the Special Interest Sessions on Synchrotron Radiation for the ACA meetings. The Chair-Elect shall serve in a special advisory capacity to the Chair and shall act in his capacity if for any reason the Chair cannot act.  The Chair-Elect shall also serve to represent the Group to the Council of the Association and to be the Group's representative on the Program Committee of ACA meetings.  The duties of the Immediate Past Chair shall include the keeping of minutes of meetings, maintaining the membership list, reporting the activities of interest to the membership, and keeping a record of finances and expenditures of the Group in collaboration with the Treasurer of the ACA.  Wherever possible, all notices to the Group shall be circulated along with the Newsletter of the ACA.
