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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

In this work a new single anode spherical tissue-equivalent proportional counter (TEPC) was developed for mixed field radiation dosimetry. The approach used was to divide the cathode into several rings with different thicknesses and adjust the potential difference between each ring and the anode to produce an electric field that is nearly constant along the length of the anode. A-150 tissue-equivalent plastic is used for the detector walls, the insulator material between the cathode rings is low-density polyethylene, and the gas inside the detector is propane. The detector, along with the charge sensitive preamplifier, is encased in a stainless steel vacuum chamber. This 1.8-cm-diam TEPC provides low electronic noise, a gas gain of 550 at 782 V, good spectral resolution (26 keV/m), and a full-width at half-maximum value of 17%. This spherical TEPC detector system will improve the accuracy of dosimetry in space and as a result improve radiation safety for astronauts.
