Abstract
An RF apparatus may include: an RF resonance device having an electrically conductive outer wall, the outer wall comprising a gap extending over its circumference, and an input coupling device having an RF generator, arranged on the outer side of the outer wall of the RF resonance device in the region of the gap, for coupling RF radiation of a particular frequency through the gap into the interior of the RF resonance device, and shielding which externally shields the generator and electrically bridges the gap on the outer side of the outer wall, wherein the shielding is formed as a resonator having a high impedance at the generator frequency.

An RF apparatus comprising:
- an RF resonance device having an electrically conductive cylindrical outer wall defining a cylindrical RF cavity, the cylindrical outer wall having a first circumferential wall section with a first flange extending therefrom and a second circumferential wall section with a second flange extending therefrom, wherein the first and second flanges extending from the first and second cylindrical outer walls are separated from each other by a gap extending around a circumference of the outer wall, and
- an input coupling device for coupling RF power into the RF cavity comprising:
- an RF generator arranged on an outer side of the outer wall of the RF resonance device in a region of the gap, the RF generator coupling RF radiation of a particular generator frequency through the gap into an interior of the RF resonance device, and
- shielding configured to externally shield the generator and electrically bridge the gap on the outer side of the outer wall,
- wherein the shielding is formed as a resonator with a high impedance for the particular generator frequency, and
- wherein the generator comprises a plurality of transistor modules distributed around the circumference of the RF resonance device, wherein each transistor module is (a) physically coupled to the first and second flanges of the first and second circumferential wall sections and (b) extends completely across the gap in a longitudinal direction.
A particle accelerator comprising:
- at least one RF apparatus, each comprising:
- an RF resonance device having an electrically conductive cylindrical outer wall defining a cylindrical RF cavity, the cylindrical outer wall having a first circumferential wall section with a first flange extending therefrom and a second circumferential wall section with a second flange extending therefrom, wherein the first and second flanges extending from the first and second cylindrical outer walls are separated from each other by a gap extending around a circumference of the outer wall, and
- an input coupling device for coupling RF power into the RF cavity comprising:
- an RF generator arranged on an outer side of the outer wall of the RF resonance device in a region of the gap, the RF generator coupling RF radiation of a particular generator frequency through the gap into an interior of the RF resonance device, and
- shielding configured to externally shield the generator and electrically bridge the gap on the outer side of the outer wall,
- wherein the shielding is formed as a resonator with a high impedance for the particular generator frequency, and
- wherein the generator comprises a plurality of transistor modules distributed around the circumference of the RF resonance device, wherein each transistor module is (a) physically coupled to the first and second flanges of the first and second circumferential wall sections and (b) extends completely across the gap in a longitudinal direction.
