A webinar, and a new opportunity to take ANS’s CNP Exam
Applications are now open for the fall 2025 testing period for the American Nuclear Society’s Certified Nuclear Professional (CNP) exam. Applications are being accepted through October 14, and only three testing sessions are offered per year, so it is important to apply soon. The test will be administered from November 12 through December 16. To check eligibility and schedule your exam, click here.
In addition, taking place tomorrow (September 19) from 12:00 noon to 1:00 p.m. (CDT), ANS will host a new webinar, “How to Become a Certified Nuclear Professional.” More information is available below in this article.

We describe here the RF system currently installed on Alcator C that is being used to inject in excess of 1 MW of net RF power into the tokamak plasma during lower hybrid heating and current drive studies. This system provides for RF power and phase monitoring in each of the individual waveguides of the two 16 waveguide launching arrays, and also for fault protection both at the waveguide arrays and klystrons. Using this system good waveguide-plasma coupling has been obtained and net RF power densities of 9 kW/cm2 have been injected by the waveguide array without microwave arcing.
