ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.

Along the upgrade program of ECRH system in GAMMA10, the gyrotron of 500kW level at 28GHz has been developed. The first 500kW gyrotron delivered 500kW at the windows and contributed to produce high ion confining potential. During the operation, it is found that there were some points to be improved: 1) Saturation level of output is smaller than expected. 2) Body current is large. 3) Beam over current occurs frequently. The second gyrotron was redesigned to improve these three points for stable operation. The second one has been changed in the design of internal mode converter, the shape of structure in collector and the slope of internal top roof of the collector. As a Result of 3 improved points, the maximum output power increased from 516kW to 570 kW, body current decreased from 5mA to 2mA, and the rate of beam over current decreased from 7% to 4%.
