Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

New company has big nuclear plans
The recent startup The Nuclear Company announced plans this month to deploy a series of nuclear reactors by the mid-2030s using a “design-once, build-many approach.”
The venture-capital-funded firm wants to use proven, licensed technology and target sites that already have some level of licensing approval from the Nuclear Regulatory Commission to build enough reactors to produce 6 gigawatts of electricity across the country.

For nearly two decades, as many as 4 Inertial Electrostatic Confinement (IEC) devices have been operated simultaneously at the University of Wisconsin-Madison. Over that time period we have learned that the early perceptions of how IEC devices operate are quite different from the actual performance in the Laboratory. Over the past 2 years we have gained even more understanding of IEC physics and technology. Experimental measurements and theoretical improvements have better characterized both the negative ions that contribute up to ~10% of the fusion rate in some cases and the neutral energy distributions in IEC devices at moderate pressure (0.07-0.7 Pa ≈ 0.5-5 mTorr). We also now understand more of why operation with helium plasmas has such a detrimental effect on high voltage performance of the traditional tungsten alloy grid wires. Most of the previous IEC work had been confined to < 100 kV with short operation times up to 150 kV. We have recently expanded our operating regime to ≈ 200 kV anode-cathode potential difference, which is, to our knowledge, the highest-voltage IEC operation reported in the worldwide IEC literature. Several design modifications were required to achieve steady state operation at these high voltages and some are described in this article.
