Introduction

The Physics Department activities for the summer 2014 are summarized in this report.

Both, faculty and students were involved in multiple activities in research, outreach and education, both on and off campus. Our faculty visited institutions overseas, where they pursue very active collaborative research. They also attended and organized conferences, and gave oral presentations at those conferences on visited institutions. Faculty members performed high profile service nationally and internationally.

Faculty were also involved in multiple outreach and education activities, including graduate and undergraduate student mentorships, high and middle school student mentorships, a 6-12 teacher programs such as the 2014 Optics Workshop for 6-12 Science Teachers, a middle school summer program called PING (Physicist Inspiring the Next Generation), and the organization of high profile summer schools such as the HUGS summer school for graduate nuclear physics students. Faculty members also stayed busy preparing grant proposals with the aim at submitting them in the fall and a few new grants were awarded.

Two students defended successfully PhD theses, keeping with the very successful trajectory of the

Department's PhD program. Many of our students attended and presented at several conferences and workshops, REU programs and other summer programs.

Details on the activities outlined above are presented below. They attest to the high level of

engagement of the Physics Department in all its areas of activity, and hopefully project the dedication and enthusiasm of all members of the Department.

Strategic Plan Update

• Dr. Jose Goity will serve as interim chair of the department during the Fall Semester.

• Dr. Michael Kohl, continued to serve as Spokesman of the TREK/E36 experiment at the J-PARC facility in Japan. The experiment studies the decays of kaons to test lepton flavor universality and to search for new particles such as massive sterile neutrinos and neutral gauge bosons. Dr. Kohl continues to supervise graduate student Mr. Bishoy Dongwi in the development of a Geant4 simulation for the TREK/E36 experiment at J-PARC. Dr. Kohl also serves as Physics Coordinator of the OLYMPUS experiment at DESY in Hamburg, Germany, an experiment to study the effect of two-photon exchange with high precision, and as Co-Spokesperson on the proposed experiment E12-11-009, a measurement of the neutron electric form factor in Hall C at Jefferson Lab.

• Dr. Paul Gueye is continuing in the implementation of a new accelerator physics program in the Physics Department centered on a 100 kV DC thermionic electron gun that was used in the early years of Jefferson Lab’s scientific program: two models of the thermionic gun were completed, two elective courses developed and one dedicated staff hired jointly with the Department of Biology and the possible hiring of a new junior faculty in the 2014-2015 academic year. The sole PhD student of the Jefferson Lab Polarized Electrons of Polarized Positrons (PEPPo) experiment, Mr. Adeleke Adeyemi, is in the final stage of his data analysis and is expected to graduate in 2015.

• Dr. Ei Ei Brown will utilize her newly funded NSF (HBCU-UP) grant to focus on finding new rare-earth scintillator (radiation dector) materials for applications in homeland security, monitoring nuclear materials, or medical diagnosis. This work involves a systematic study on the material purification process, Bridgman crystal growth, photoluminescence spectroscopy, and radiation detection experiments of rare-earth doped lead based halides. The knowledge gained from this research experience will provide undergraduate students with insight into learning science through discovery, hands-on lab training, efficient technical problem solving skills, and help outline their future professional career goals.

• Dr. Lars Ewell and the Medical Physics group within the Department of Physics will continue to make progress towards its goal of becoming a pre-eminent center of scholarly activity. The primary mission of educating our MS and PhD students, along with pushing the boundaries of medical physics research remains unchanged. To this end, over the summer the medical physics group presented work in which they collaborated with clinical medical physicists from the Hampton University Proton Therapy Institute (HUPTI) at the annual meeting of the American Association of Physicists in Medicine (AAPM, see below). In addition, Dr. Ewell will continue to work on getting the program accredited by the Commission on Accreditation of Medical Physics Educational Programs (CAMPEP, see http://www.campep.org/ ). The Self-Study document related to this accreditation is planned for submission in the early fall semester.

This program is a part of the National Girls Inc. program and is expected to provide new venues to significantly increase the participation of girls in STEM fields. A dedicated collaborative grant between the Physics Dept. and Girls Inc. of the Greater Peninsula will be submitted in the fall of 2014.

• Dr. Alberto Accardi served as director of HUGS 2014 Graduate Summer Program from June 2-21, 2014. HUGS is now in its 29th edition and was recognized by the DOE Secretary Muniz during his visit on campus in January as an outstanding example of nuclear physics workforce training for the future of the country. Organized in partnership with Jefferson Lab, the 2014 HUGS program saw 32 students from across the globe gathering to attend lectures by distinguished speakers and seminars by Jefferson Lab and Hampton University researchers. During the last week, the students attended a special workshop on “Physics Careers at HUGS,” organized for the first time this year by Dr. Accardi and Ms. Natalie Walford, and presented their own research in a two-day long student seminar series. This workshop presented graduate students and post-graduate researchers in nuclear physics a perspective on academic and non-academic careers open to them as they graduate, or look for their next step in their post-doc career; it included a hands-on session with practical advice on resume and CV writing. The school received excellent student evaluations, and is projected to continue growing in attendance in the next years.

• Dr. Felix Jaetae Seo organized the 2014 Optics Workshop for 6-12 Science Teachers: ACLaSS. The 2014 Optics and Laser Science Summer Workshop was held at Hampton University on June 23-27, 2014 in order to promote the science education in grades 6 – 12. The participating science teachers were selected from forty-nine public and private high-schools in Hampton Roads which covers Chesapeake, Hampton, Jamestown, Newport News, Norfolk, Portsmouth, Suffolk, Virginia Beach, Williamsburg and Yorktown in the state of Virginia. One of the science teachers participated

14

from Pennsylvania. The participating teachers performed four modules. The first module entitled “Polarization of Light” aimed to introduce the property of polarization of light through reflection, Brewster’s angle, and applications. The second module entitled “Reasons for Seasons” was proposed to explain the true reason for seasonal variations in temperature. This module was inspired by the fact that many people believe that the distance from the sun is the reason for seasons, this module shows, with simple supplies, that the angular tilt of the earth axis with respect to the normal to earth’s rotational plane is the true factor. The third module of “The Pretty Colors” was based on spectroscopy. Different light sources were used to analyze their spectral components using spectroscopes and spectrometers. The fourth and last module “Reflection of Light” had an interesting idea of recycling household items and using arts and crafts to build a kaleidoscope where the students experiment with the reflections of light. Four invited speakers presented to the teachers; Dr. Tarek Abdel-Fattah from Christopher Newport University (CNU) presented about his research on carbon nanotubes, Dr. Mahmoud Abdel-Fattah from Hampton University presented about the properties of light, Dr. Sainath Babu from Hampton University presented about PBA toxicology, and Dr. Wei Cao from Old Dominion University (ODU) presented about the electron microscope. The teachers enjoyed a site visit to the Hampton University Proton Therapy Institute (HUPTI) where they received a tour by the executive director Mr. Keith Gregory that was very interesting and educational. Finally, the teachers gave their own presentations that included their comments and tweaks of the four modules.
