Deep Fission to break ground this week
With about seven months left in the race to bring DOE-authorized test reactors on line by July 4, 2026, via the Reactor Pilot Program, Deep Fission has announced that it will break ground on its associated project on December 9 in Parsons, Kansas. It’s one of many companies in the program that has made significant headway in recent months.

Thomson scattering system based on a ruby laser was applied in the GDT to measure the electron temperature during intense neutral beam injection. The system is capable of measuring the radial profile of electron temperature in the midplane over plasma radii varying from 0 to 12 cm. For this purpose the focusing lens is moved from shot to shot along the laser beam. The scattered light condenser with the polychromator is correspondingly rotated. Angle of scattering is in the range of 86–97 degrees. Thomson scattering system enables measurement of the electron temperature at minimal plasma density of ∼1013 cm−3. The time between shots (about 3 minutes) is long enough to collect, store the data and subsequently calculate the electron temperature. In the paper, the data on radial profiles and temporal behaviour of electron temperature during neutral beam heating at GDT are presented. In the experiments, electron temperatures of the target exceeding 100 eV was observed.
