Abstract
Embodiments of systems, devices, and methods relate to an ion beam source system. An ion source is configured to provide a negative ion beam to a tandem accelerator system downstream of the ion source, and a modulator system connected to an extraction electrode of the ion source is configured to bias the extraction electrode for a duration sufficient to maintain acceleration voltage stability of the tandem accelerator system.

1-67. (canceled)
A boron neutron capture therapy (BNCT) system, comprising:
- a tandem accelerator system comprising a plurality of capacitors;
- an ion source configured to provide a negative ion beam to the tandem accelerator system;
- a modulator system connected to an extraction electrode of the ion source, wherein the modulator system is configured to:
- bias the extraction electrode until steady state ion extraction and acceleration voltage stability of the tandem accelerator system is achieved;
- and
- discontinue biasing the extraction electrode when a measured voltage across two or more of the plurality of capacitors of the tandem accelerator system is reduced below a threshold;
- and
- a target device downstream from the tandem accelerator system configured to form a neutral beam from a positive beam received from the tandem accelerator system.
