Description
The RF buncher used in the Los Alamos Neutron Science Center (LANSCE) Proton Storage Ring (PSR) is facing obsolescence of several critical parts that would prevent sustaining operations into 2050. The present RF buncher uses triodes for its cathode-follower configuration that are no longer produced, and because no similar tubes exist to replace these triodes, an alternate bunching system must be developed. A Gallium Nitride (GaN) transistor-based preamplifier may be used to drive a tetrode final amplifier because the wide bandgap semiconductor has better radiation tolerance than silicon transistors. Additionally, improvements to the ferrite-loaded resonator must be made to accompany these changes and account for obsolescence of the ferrite. Measurements of ferrites used in the present buncher have been made, and the material considerations for replacing the obsolete resonator ferrites will be presented.
