Radio-frequency power generator configured to reduce electromagnetic emissions

A radio frequency (RF) power generator comprising:

• an outer enclosure having a system cavity, the outer enclosure separating the system cavity from an exterior of the RF power generator;
• an RF amplification system disposed in the system cavity and emitting electromagnetic radiation while producing electric power for energizing a particle accelerator, the outer enclosure being configured to reduce leakage of the electromagnetic radiation into the exterior;
• and
• an inner enclosure positioned within the system cavity, the system cavity including an outer space that exists between the inner and outer enclosures, the inner enclosure including interior walls that form a plurality of compartments having respective access openings that open to the outer space, the inner enclosure including a movable access panel that is configured to engage the interior walls and cover the access openings, the RF amplification system being located within at least one of the compartments, the inner enclosure being configured to reduce leakage of the electromagnetic radiation into the outer space and the exterior.
