Broader Impacts
\begin{center} {\it \underline {Broader Impacts of the Proposed Activities}} \end{center}
In addition to the scientific program described here, this proposal represents a major effort in the area of educating future scientists. The present shortage of graduate students in experimental and theoretical nuclear physics is having a detrimental impact on our national laboratories and facilities which posses a plethora of data but limited manpower for analyzing and disseminating the information. The Idaho State University Department of Physics is comprised of nine tenure-track faculty, all of whom have research interests which are in some way connected to nuclear physics and are in a position to directly address the shortage of graduate students. With its on campus accelerator and detector laboratories, the Department focuses on experimental and applied physics, giving students a strong hands-on educational experience. ISU's physics program is relatively new and rapidly growing.
- include the two sentences below?
Last year, ISU physics faculty brought in approximately \$8 million in external research funds. Its Ph.D.~program, established in the Fall of 2005, presently has approximately 30 students with an additional 15 students pursuing research at the M.S.~level.
The PIs are further strengthening the ISU graduate program by recruiting high-caliber students from Latin America. Latin America remains an underutilized intellectual resource. The ISU Group has strong ties to Colombia and has attracted four talented graduate students into nuclear physics at ISU; three are working on JLab-related projects and one graduated in late 2009 and is now an Assistant Professor in Bogot\'{a}, Colombia. The activities delineated within this proposal will provide another avenue through which the program can continue to solidify this mutually beneficial bridge of collaboration among countries in the Americas.
Project Description
Introduction
We propose to perform measurements using electromagnetic probes at Jefferson Lab that will enhance our fundamental understanding of nucleons and nuclei. The experiments within this proposal perform measurements of a nucleon's constituents, the size of the proton, and the surface of a nucleus.

5 students
Section on training our JLab students in Hardware
Student do physics at JLab and gain experience with hardware using ISU facilities.
CLAS can also be categorized as a bunch of "One off" experiments. Perhaps review publication record of the experiments. PV experiments take 10 years from construction to publication some CLAS experiments took less.
