Physics 518. Spring 2012


April 30

This Thursday's class is at Stony Brook, Physics building, room P-119, starting at 3:00.
Lecture topics are x-ray microscopy and small angle scattering (postponed from April 19th).

I will be circulating some materials on writing beamtime proposals, the topic originally planned for the May 3 class. I plan to schedule a one hour meeting with each of you in the week of April 30 - May 4 to talk about your research interests and what kind of research proposal you would like to write. (Not necessarily for a real experiment, but very nice if it can be – that's what we'll talk about.)

Meantime, go on the NSLS PASS (Proposal Allocation Safety Scheduling – web page and click on Create a new PASS Form. I will be providing some more info here, including an actual beamtime proposal that I am writing, as I develop it.


Physics 518. Applications of Synchrotron Radiation.

Instructor: Peter Stephens
Office: Physics room B134
Phone: SB: 632-8156. BNL: 344-5816, 344-8210.

This course is an overview of synchrotron sources and applications, intended for graduate students in physics, chemistry, geosciences, biology, materials science and engineering, and related fields, as well as staff at synchrotron radiation facilities. It will provide a systematic view of modern facilities for production of synchrotron radiation, the principles of various techniques of diffraction, spectroscopy, microscopy, etc., and the science enabled thereby.

The first class meeting is Thursday, January 26, in room P119 of the Physics Building at Stony Brook University. Most of the later classes will meet in the seminar room of the National Synchrotron Light Source. Transportation arrangements will be discussed at the first class meeting.

In order to gain access to Brookhaven Laboratory, all students must have access to the BNL site, preferably through guest appointments. We will go through the process to obtain those in the first class meeting.

The amount of course work will be rather small, as the course will mostly consist of presentations by expert practitioners, associated either with Stony Brook University or the Photon Sciences Directorate of Brookhaven National Lab. As such, the course is not intended to meet the breadth requirement of the Physics and Astronomy department, or the degree requirement of six 3-credit science courses in the Chemistry department. (Credits for graduate courses are a confusing morass. Students for whom this is an issue should discuss with the instructor and their graduate program director.)

Grading is S/U. The requirements of the course are:
1) Attend most (to be defined) of the lectures.
2) Use the NSLS Proposal Approval and Safety System to prepare a well-argued proposal to perform an experiment (hypothetical or real).
3) Write a brief (1 paragraph) evaluation of the proposal submitted by one of the other students.

Academic Integrity:

Each student must pursue his or her academic goals honestly and be personally accountable for all submitted work. Representing another person's work as your own is always wrong. Faculty are required to report any suspected instances of academic dishonesty to the Academic Judiciary. For more comprehensive information on academic integrity, including categories of academic dishonesty, please refer to

Crisis Incident Management:

Stony Brook University expects students to respect the rights, privileges, and property of other people. Faculty are required to report to the Office of Judicial Affairs any disruptive behavior that interrupts their ability to teach, compromises the safety of the learning environment, or inhibits students' ability to learn.
