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.

The effects of operating gas pressure on a Cylindrical Inertial Electrostatic Confinement Fusion (IECF) device are investigated. First we did glow discharge experiments, and we obtained 1.8 × 106 neutrons production per second with 45-kV, 44-mA discharge at 1.2 Pa. Next we modified the device and tried to reduce the operating gas pressure with an ion source, aimed to increase neutron production. Although the discharge currents are small, we can make steady discharges at less than 0.1 Pa. The neutron production rates per current are larger than those of glow discharge at higher pressure. We consider it should suggest the validity of reducing operating pressure in IECF devices.
