Protons spin. It's an intrinsic property that can affect experiments at accelerators that use beams of protons.  The world's most advanced particle accelerator for investigating the quark structure of the atom's nucleus has just charmed physicists with a new capability.  Bob Zwaska, a scientist at the U.S. Department of Energy's Fermilab, was watching a contestant on the cooking show Chopped spin sugar for their dessert when he realized the same principle might be applicable to accelerator targets.  Physicists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have discovered valuable information about how electrically charged gas known as "plasma" flows at the edge inside doughnut-shaped fusion devices called "tokamaks."  A class exercise at MIT, aided by industry researchers, has led to an innovative solution to one of the longstanding challenges facing the development of practical fusion power plants: how to get rid of excess heat that would cause structural damage to the plant.  Schematic of a magnetic nozzle rf plasma thruster (helicon plasma thruster) having two open source exits and photographs of the three operation modes in the laboratory test.  Researchers at MIT's Plasma Science and Fusion Center (PSFC) have now demonstrated how microwaves can be used to overcome barriers to steady-state tokamak operation.  Plasma particle accelerators more powerful than existing machines could help probe some of the outstanding mysteries of our universe, as well as make leaps forward in cancer treatment and security scanning-all in a package that's around a thousandth of the size of current accelerators.  The Department of Energy's SLAC National Accelerator Laboratory has started to assemble a new facility for revolutionary accelerator technologies that could make future accelerators 100 to 1,000 times smaller and boost their capabilities.
