Geoffrey Rothwell: My story—ANS member since 1986
When I was 10, in October 1963, my family moved to Richland, Wash., so that my father could work for Vitro-Hanford Engineering Services, later for Bechtel, on the design of the Fast Flux Test Facility. I was a “new” kid throughout my excellent education in the Richland School District. It was the mid-1960s, and I wanted to be a rocket scientist or aerospace engineer. I took all the math and science that Richland High School (RHS) had to offer. What struck me during our tour of Hanford’s N-reactor with my physics class was the loudness of the steam turbine room compared to the hydro turbine rooms in the dams along the Columbia River. I am now establishing a residence on Columbia Point Drive in Richland.

We have measured detailed axial profiles of electron density, floating potential, and axial magnetic field in the field-reversed configuration (FRC) sustained by the rotating magnetic field. To study the influence on the equilibrium of two kinds of bias magnetic field configuration - straight (pure solenoidal) and mirror -, experiments have been carried out in the FRC Injection Experiment apparatus. The case of mirror configuration has longer quasi-steady state compared with the case of straight configuration. The steeper density gradient outside the separatrix is generated by the uniform gradient of magnetic field due to the mirror configuration. The axial parallel diffusion is suppressed due to the steeper density gradient outside the separatrix. Therefore, the mirror bias magnetic field configuration works to improve the plasma confinement.
