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.

ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

A Boron-lined proportional counter has been developed whose cathode diameter varies continuously, hence varying the gas multiplication along the length of the counter. The sensitive area of the cathode thus becomes a function of the applied voltage, electrical amplification, and pulse-height discrimination. A semi-empirical relationship between counter geometry, gas parameters, and applied voltage is used to develop theoretical expressions for the dependence of count rate on applied voltage and cathode geometry. The behavior of cathodes of hyperbolic and exponential shape is treated. A prototype exponential counter, operated in a pulse counting mode, was constructed and tested. The approximately logarithmic relationship between neutron flux and voltage predicted for such an instrument was confirmed.
