How cool are cool roofs? PPPL serves as the laboratory to find the answer
When Keith Rule and a team of interns walked onto the black and white roof of the main building of the US Department of Energy's Princeton Plasma Physics Laboratory one sweltering day last summer, they could feel the temperature difference between the two different colored areas in the soles of their feet.

PPPL developes internet-based simulation capabilities
Physicists at Princeton Plasma Physics Laboratory are developing internet-based interfaces which will allow researchers to access powerful simulation tools used to interpret experimental data and predict plasma behavior in future experiments.

PPPL-led team completes work on JET alpha detector
Studying the behavior of alpha particles produced in fusion plasmas is of paramount importance for ITER and other advanced fusion devices in which these particles are expected to be the predominant source of plasma heating. An international team led by PPPL physicist Doug Darrow recently completed work at PPPL on the construction of diagnostic equipment that will be used to measure alpha particles and other energetic particles ejected from the plasma in the Joint European Torus (JET) in Culham, England.

Small is big for PPPL's Paul Trap
The Paul Trap Experiment at the Princeton Plasma Physics Laboratory is trying to determine the properties of intense charge particle beams as they travel through transport systems. But PTSX, measuring only three meters in length -- much shorter than a typical particle accelerator -- uses some interesting physics to simulate the conditions in an accelerator.

MRI experiment operational at PPPL
The formation process of stars and planets remains one of the big questions in astrophysical science. Currently, scientists do not understand the required conditions and the accretion, or matter collection process, involved in star and planet formation. But the Magnetorotaional Instability (MRI) experiment now operational at the Princeton Plasma Physics Laboratory may shed light on this mystery.

PPPL researchers study plasma sterilization
Hundreds of billions of plastic food and beverage containers are manufactured each year in the U.S. All of these packages must undergo sterilization, which at present is done using high temperatures or chemicals. Both of these methods have drawbacks. What if a new method could be found that eliminated the need for chemicals or heat-resistant plastics?

Imaging system visualizes plasma turbulence
Researchers from three laboratories funded by the U. S. Department of Energy have captured high-resolution images of instabilities that cause heat to leak rapidly from the plasma edge of the National Spherical Torus Experiment (NSTX) and the Alcator C-Mod fusion experiments. Advanced imaging cameras were used to freeze plasma action at a rate of up to 1 million frames per second.

PPPL develops detection system to boost anti-terror efforts
Anti-terrorism efforts may get a boost from the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL). A team led by PPPL engineer Charlie Gentile is developing a miniature nuclear detection system to scan objects such as cars, luggage, and vessels for specific nuclear signatures associated with materials employed in nuclear weapons. This system could be installed at tollbooths and airports, as well as in police cruisers to detect unauthorized nuclear materials being transported.
