The Department of Physics offers B.S., M.S., and Ph.D. degrees in physics. Within the department, there are many opportunities for interdisciplinary education and research experiences; students in any of the disciplines have easy access to the expertise that the full faculty brings. In addition, the department offers a professional master’s degree and related certificate program for part-time students, both on campus and through distance learning.

## Research Centers

Center for Accelerator and Particle Physics

Center for the Molecular Study of Soft and Condensed Matter

Center for Synchrotron Radiation Research and Instrumentation

## Research Facilities

The department has state-of-the-art computer and laboratory equipment and conducts research in the areas of elementary particle physics, accelerator and plasma physics, condensed-matter physics, biological physics, x- ray optics, x-ray imaging, and quantum theory. The department constructs and operates facilities for x-ray scattering, spectroscopy, and imaging at the Advanced Photon Source at Argonne National Laboratory. Additional research facilities include on-campus x-ray diffraction facilities, thin-film growth facilities, a high-field nuclear magnetic resonance facility, Fourier transform infrared spectrometers, and atomic force microscopes. Laboratories for experimental research in biophysics, low-temperature, solid-state physics, and particle physics are active. Collaborative programs are carried on with Fermi National Accelerator Laboratory, Argonne National Laboratory, and the Advanced Photon Source. The department hosts the Center for Accelerator and Particle Physics (CAPP), the Center for the Molecular Study of Soft and Condensed Matter, and the Center for Synchrotron Radiation Research and Instrumentation (CSRRI).

## Departmental Graduate Examinations

All full-time students in the M.S. and Ph.D. programs are required to take and pass the written M.S. comprehensive/Ph.D. qualifying examination by the end of their fourth semester of study. Part-time students must pass this examination by a comparable stage of their programs. The examination is offered twice each academic year. A student may sit officially for the examination a maximum of two times. Students passing this examination at the Ph.D. level are judged to be qualified to continue in the Ph.D. program. Students passing at the master of science level or above may obtain their master’s degree after completing the requirements described in the following sections. All students in the Ph.D. program who have passed the written qualifying examination must take and pass a comprehensive examination at least one year prior to the final oral defense. Part-time students must pass this examination by a comparable stage of their programs. The comprehensive examination consists of a written proposal, an oral presentation, and a defense of the proposal before a faculty committee. A student may take this examination a maximum of two times. Students passing this examination may continue with their research and will receive a Ph.D. upon satisfactory completion of all other required courses and general requirements of the Graduate College, a written dissertation, and final oral thesis defense.

All students in the professional master’s degree program are required to take and pass a comprehensive exam. Students may sit for the exam a limited number of times.

## Admission Requirements

Cumulative undergraduate GPA minimum: 3.0/4.0

TOEFL minimum: 550/213/80^{1}

The Graduate Record Examination (GRE) is required for all applicants. The GRE minimum scores are:

### MAS

295 (quantitative + verbal); 2.5 (analytical writing)

### M.S.

295 (quantitative + verbal); 2.5 (analytical writing)

### Ph.D.

310 (quantitative + verbal); 3.0 (analytical writing)

Applicants to the doctoral program in physics are strongly encouraged, but not required, to take the subject-area GRE exam in physics.

Meeting the minimum GPA and test score requirements does not guarantee admission. Test scores and GPA are just two of several important factors considered.

Applicants to the department’s program are expected to have a bachelor’s degree from an accredited institution with a major in that same discipline, or a closely allied major with additional coursework that prepares the student for graduate study in the chosen program. Students who have not completed all required courses may be accepted for general admission and can begin coursework, but must remove any deficiencies before the MAS or M.S. comprehensive/Ph.D. qualifying examination.

The department offers programs leading to M.S. and Ph.D. degrees in physics, along with a M.S. degree in applied physics. The M.S. degree is not a prerequisite for the Ph.D. The department also offers a professional master’s program in health physics designed for both the part-time and full-time student and available through distance learning. Research is organized into small groups of faculty members, post-doctoral associates, graduate students, and undergraduate students working on closely related projects. The principal active areas include experimental and theoretical condensed matter physics, experimental and theoretical elementary particle physics, synchrotron radiation physics, accelerator physics, structural and computational biophysics, magnetism, and electrodynamics. Classes are generally small and informal, and thesis research is carried out in close collaboration with the faculty adviser.

In recognition of the value of teaching experience in strengthening an individual’s understanding of his or her field of study and as an aid in making career decisions, the department requires full-time students to participate in instructional activities. Each new graduate student is assigned a graduate student adviser and must obtain the approval of the adviser each semester before registering for any graduate classes.

## Degrees Offered

- Master of Health Physics
- Master of Science in Applied Physics
- Master of Science in Physics
- Doctor of Philosophy in Physics

## Co-Terminal Options

### Bachelor of Science in Physics/Master of Health Physics

Undergraduate students may register for the co-terminal Bachelor of Science in Physics/Master of Health Physics after the fourth semester of study. Students must fulfill the requirements of both the Bachelor of Science in Physics and the Master of Health Physics. A full course of study is approximately ten semesters of study, and graduate coursework typically begins in the fourth year. For further details, refer to Synopsis of Co-Terminal Studies section in this bulletin.
