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.

Design study of the magnetic configuration and divertor geometry for the “advanced divertor” in a Demo tokamak reactor is summarized. Equilibrium calculation code, TOSCA, was developed for the super-X divertor (SXD) design by introducing two parameters, i.e. location of the super-X null and a ratio of the poloidal magnetic fluxes at the super-X null to that at the separatrix. SXD has an advantage to increase connection length from the divertor null point to the divertor target (L//div), which is 1.6-1.8 times larger with increasing fSX, compared to that in the conventional long-leg divertor. Whereas flux expansion near the super-X null was increased, increase in the target wet area (Awet) was small. Snowflake divertor (SFD) magnetic configuration was produced by adjusting PFC locations and the current distribution. L//div was largely increased near the SF null in the conventional divertor size. Key issues remain: control scenario for SFnull and high plasma shaping should be developed, and appropriate SFD design is necessary. For the advanced divertor design, divertor coils inside TFC are preferable due to the maximum current and size.
