Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

The conservative physics and conservative technology tokamak power plant ARIES-ACT2 has a major radius of 9.75 m at an aspect ratio of 4.0 and has strong shaping with elongation of 2.2 and triangularity of 0.63. The plasma current is 14 MA, and the toroidal field at the plasma major radius is 8.75 T, making the maximum field at the toroidal field coil 16 T. The no-wall βN reaches ∼2.4, limited by n = 1 external kink mode, and can be extended to 3.2 with a stabilizing shell behind the ring structure shield. The bootstrap current fraction is 77% with a q95 of 8.0, requiring ∼4.0 MA of external current drive. This current is supplied with 30 MW of ion cyclotron radio frequency/fast wave and 80 MW of negative ion neutral beams. Up to 1.0 MA can be driven with lower hybrid (LH) with no wall, and 1.5 or more MA can be driven with a stabilizing shell. Electron cyclotron was examined and is most effective for safety factor control over ρ ∼0.2 to 0.6 with 20 MW. The pedestal density is ∼0.65 × 1020/m3, and the temperature is ∼9.0 keV. The H98 factor is 1.25, n/nGr = 1.3, and the net power to LH threshold power is 1.3 to 1.4 in the flattop. Because of the high toroidal field and high central temperature, the cyclotron radiation loss was found to be high depending on the first-wall reflectivity.
