Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

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 initial design study of 28 GHz/35 GHz dual frequency gyrotron is presented. The design is based on 28 GHz 1 MW gyrotron which we have developed. And it is studied whether 35 GHz oscillation is possible or not using the present 28 GHz gyrotron cavity. From the numerical simulation results, the cavity can form 35.45 GHz TE9,4 mode oscillation of over 1 MW oscillation power with high efficiency. However, in the present mode converter and transmission mirror system, the radiated RF power through the output window is only about 70 % of the 35.45 GHz oscillation power because of the radiation angle difference of 15.85°. For more high efficiency operation for 35 GHz, we will re-design the cavity in which there are good candidate modes such that there is no radiation angle difference.
