PM-1100X X-Band CyberKnife Magnetron

The PM-1100X is a medical linac magnetron manufactured by California Tube Laboratory (CTL). Mechanically tunable X-band pulsed magnetron at 9.3 GHz with 1.5 MW peak power — the original RF source for the Accuray CyberKnife robotic radiosurgery linac and the IntraOp Mobetron intraoperative system.

Key ratings of the PM-1100X include frequency 9.3 GHz, frequency band X-band, type Pulsed, mechanically tunable, peak power 1.5 MW, average power 1.5 kW and pulse width 1.0 µs.

Typical applications are accuray CyberKnife X-band linear accelerator (RF source), intraOp Mobetron intraoperative radiotherapy system, compact X-band medical linac systems and stereotactic radiosurgery equipment. Notable features: 1.5 MW X-band pulsed output at 9.3 GHz, mechanically tunable for frequency matching, original-equipment RF source for CyberKnife and Mobetron and manufactured by California Tube Laboratory (CTL).

Medical magnetrons are the RF power source of compact radiotherapy linear accelerators (linacs). They operate in pulsed mode in the S-band or X-band and are fed by a thyratron-switched pulse modulator. Tube life is measured in operating hours, so hospitals and service organisations keep qualified spares to minimise treatment downtime.

PartnerTubes supplies the PM-1100X worldwide from Groningen, the Netherlands — availability, lead time and price are confirmed per enquiry. Our team can help with equivalent and cross-reference types, sockets and accessories, and supply programmes for OEM and maintenance customers. Interchangeability must always be confirmed for the specific equipment.
