摘要： Radio-frequency (RF) electrode for a cyclotron. The RF electrode includes a hollowed dee having first and second surfaces that oppose each other and define a gap therebetween. The hollowed dee is configured to be electrically controlled to direct a beam of charged particles through the gap and along an orbit plane of the cyclotron. The orbit plane extends parallel to the first and second surfaces through the gap. The RF electrode also includes a bridge structure that is coupled to and extends away from the hollowed dee. The bridge structure includes a side wall that defines an interior cavity of the bridge structure. The side wall has a particle opening therethrough that coincides with or is proximate to the orbit plane such that the particle opening receives neutral particles from an orbit of the charged particles.

摘要： RF amplification system includes a power cavity and a coupling loop operably positioned within the power cavity between an inner conductor and an outer conductor. The coupling loop includes a secured segment that is coupled to the grounding deck and a movable segment that is coupled to the secured segment. The secured segment extends between the grounding deck and the movable segment. The coupling loop defines a loop region that correlates to an amount of inductive coupling between the coupling loop and magnetic field within the power cavity. The movable segment is movable relative to the secured segment while the secured segment is stationary to change a size of the loop region and thereby change the amount of inductive coupling.

摘要： System includes first and second amplifying circuits that are configured to receive input signals having a fundamental frequency. The system also includes first and second transmission lines that are configured to receive voltage and current waveforms from the first and second amplifying circuits, respectively. The system also includes a capacitively-compensated transmission line resonator (CC-TLR) that is configured to be electrically connected to a load having a load impedance. The CC-TLR is configured to receive and combine RF power from the first and second transmission lines. The CC-TLR has a compensation capacitance that causes the CC-TLR to present an open circuit at the fundamental frequency and present a short circuit at harmonic frequencies. Optionally, a characteristic impedance (Z0) of the first and second transmission lines and a load impedance (ZL) are unequal, and the first and second transmission lines cause a load impedance transformation.
