Guillaume, Cooper, "Effect on Focusing Fields by Ferromagnetic Cell Cores in Linear Induction Accelerators" (2023). Senior Honors Theses. 1320.
In the Los Alamos National Laboratories DARHT facility, there are two perpendicular linear induction accelerators, LIAs. The LIAs’ solenoids produce magnetic fields which focus the electron beam. Simultaneously, the accelerating pulse creates a magnetic field. These two field intensities act upon a ferromagnetic material in the cells to enhance magnetic flux density. Due to the nonlinearity of the material, this flux density will reach a saturation point. In turn, the magnetic field intensity of the axial solenoidal magnetic field will be affected and slightly altered. The width of the electron beam will increase, causing a decrease in effectiveness. Through simulation, this effect was found to be observable and repeatable. An experiment was designed for one of the accelerator cells at Los Alamos’s DARHT facility. The results of this test did not produce the hypothesized effect; however, more precise experiments can be done.
