# Graduate Programs

# UNDER CONSTRUCTION

### Preliminary Examination

All graduate candidates must pass a preliminary examination, within a timeline dependent upon their undergraduate preparation and the degree being sought.

Preliminary Examination Policy (pdf)

### We have a new 5 year B.S./M.S. degree in the Department

B.S. students in the first semester of their Junior year in the department should consider applying for the B.S./M.S., which can be combined with concentrations or double-majors as well. If admitted, you can start research toward an M.S. during your Senior year with us, and are eligible for TA/RA funding during the 5th year while you attain your M.S. in Physics.

New 5 year degree requirements (pdf).

### MS in Physics

All students are required to pass a preliminary exam (“prelim”) at the MS level. The prelim covers material in physics and mathematics normally included in the undergraduate physics curriculum. The department offers the exam at the beginning of the Fall and Spring semesters. Failure to pass this exam in the timeline established on entry to the program usually results in disenrollment from the graduate physics program.

The students course of study must be approved by the students advisory committee and must fulfill the general requirements for the masters degree with thesis and must include a minimum of 9 credit hours selected from: PHYS 505, 508, 513, 514, 515, 516, 526.

All students must complete PHYS 501 and 502 in their first two semesters.

PHYS 579 (1), Graduate-Faculty Seminar, must be taken for the first four semesters.

The preliminary examination will cover courses in physics and mathematics normally included in the undergraduate physics curriculum. Thesis topics will be chosen in consultation with an advisory committee.

Courses approved by the students advisor must fulfill the general requirements for the masters degree without thesis and must include the following:

- All students must complete PHYS 501 (1), and 502 (1) in their first two semesters.
- PHYS 590 (3)
- a minimum of 9 credit hours selected from: PHYS 505, 508, 513, 514, 515, 516, 526.
- PHYS 579 (1), Graduate-Faculty Seminar, must be taken for the first four semesters.

The preliminary examination will cover courses in physics and mathematics normally included in the undergraduate physics curriculum.

### MS in Physics with Specialization in Instrumentation

Students entering this M.S. program should have a bachelors degree in engineering, one of the sciences, mathematics, or computer science. Students will also be expected to complete at Tech basic undergraduate physics and electronics courses they have not had.

Given the varied backgrounds and interests of students in this specialty, the program of study is tailored to each students needs.

PHYS 579(1), Graduate Faculty-Seminar, must be taken for the first four semesters. In addition to the above requirements, students must satisfy the general requirements for the M.S. degree and pass a preliminary examination on undergraduate physics and electronics.

### PhD in Physics

Students of exceptional ability as demonstrated in previous courses in physics and mathematics, or in the preliminary examination, may pursue a program leading to the doctoral degree. All applicants to the physics doctoral degree program must submit GRE general and physics subject test scores.

The major doctoral programs of the Physics Department are in **astrophysics** and **atmospheric physics**. A degree in mathematical physics is offered in cooperation with the mathematics
department. Students may also work in other areas of physics in which the department
has expertise.

All doctoral students are required to pass a preliminary exam (“prelim”) at the PhD level. The prelim covers material in physics and mathematics normally included in the undergraduate physics curriculum. The department offers the exam at the beginning of the Fall and Spring semesters. Although doctoral students take the same prelim as MS students, a higher score is required of them.

Doctoral students must pass the exam at the PhD level by the timeline established on their entry into the program. A student without a Master’s degree in Physics must pass the exam at the MS level within their first year in the PhD program. Failure to pass this exam with the required scores and within the specified time usually results in disenrollment from the PhD physics program.

The following general requirements apply to all curricula: A minimum of 50 credit hours of graduate and upper-division courses approved by the students committee should be taken, of which 12 credit hours must be mathematics beyond that required of an undergraduate physics major. PHYS 501 and 502 (where required below) may be waived for those students who have completed the equivalent through an experimental masters thesis. PHYS 579, Graduate Faculty Seminar, must be taken for the first four semesters.

In addition to the general doctoral degree requirements, the following course requirements apply to all curricula:
