As a federal facility, the Princeton Plasma Physics Laboratory is operating under heightened security measures because of the events of September 11, 2001.

Upon arrival at PPPL, adult visitors must show a government-issued photo I.D. -- for example, a passport or a driver's license. Non-U.S. citizens must show a government-issued photo I.D., plus provide the following information citizenship, date of birth, and place of birth.

For the welfare of both our staff and visitors, PPPL security staff retain the right to inspect vehicles and personal packages, such as briefcases, satchels, book bags, and purses.
