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.

Different operational limits of tokamaks are reviewed. The finally limiting processes are hard or soft plasma disruptions or a strong x-ray source. The underlying events are explained as far as the physical causes are known. Treated are the density limit, the low-q-limit, the runaway limit, the β–-limit, and the vertical displacement limit. In addition, the spontaneous MHD-instability and a hollow temperature profile situation are presented. The graphical displays are experimental results from the TEXTOR tokamak.
VIII. SUMMARY
A number of practical limitations for tokamak operation was briefly discussed. These limits play an important role for the operation of future large tokamak devices. They must be avoided by all means to minimize the risk of technical defects on machine and electrical components. The physical mechanisms involved and the precursors to coming disruptions must be known and should be studied on existing experiments today. Strategies to bring the future machines into a safe state, whenever a known precursor to a tokamak disruption is detected, must be developed. Tokamak plasmas are susceptible to disruptive behaviour in the limiting parameter regimes.
