The Physics Department's main teaching and research center is the Joseph Henry Laboratories in Jadwin Hall. Constructed in 1968, Jadwin houses classrooms, study areas, research laboratories, computing facilities, the Free Electron Laser laboratory, and electronics and machine shops, as well as faculty and administrative offices. The joint math-physics library connects Jadwin Hall to the mathematics tower, Fine Hall. Adjacent to the library and connected to Jadwin is the newly built McDonnell Hall which houses classrooms and teaching laboratories, and two state-of-the-art lecture halls. There is a particularly well-equipped student machine shop in Jadwin Hall intended to give students and faculty hands-on capability for fabricating scientific apparatus and teaching aids. There is also a vacuum laboratory, a chemical laboratory, a glass-blowing shop, and electronics design facilities. Instruction in the use of all of these facilities is available to students. Also part of the Physics Department is the Elementary Particles Laboratory which houses a machining center, a class 100 clean-room, and particle detector fabrication areas.
The department is situated on the main campus of Princeton and is located close to the Princeton Materials Institute, the Engineering Quadrangle, the Molecular Biology Department, Frick Chemistry building, and the Astrophysics building. Other nearby facilities supporting physics research are the Forrestal Campus Machine Shop and the Princeton Plasma Physics Laboratory, located about 5 miles from the Princeton campus.
