Coaxial Magnetrons
General Overview
VMX3095 1.7 MW X-Band
Coaxial Pulsed Magnetrons
A magnetron is a high power microwave
oscillator in which the potential energy of an
electron cloud near the cathode is
converted into RF energy in a series of
cavity resonators. Linac magnetrons can be
used in medical linear accelerators to
accelerate electrons to create X-rays used
in radiation therapy and in cargo screening
security systems.
• High frequency stability
• Tunable ± 20 MHz
• 1.70 MW peak output power
• 1.70 kW average output power
• .001 duty cycle
• Liquid cooled anode
• Long life (>5,000 hours)
The Linac magnetron produces pulsed
high-frequency electromagnetic waves to
accelerate electrons to high energies
through a linear accelerator to create X-rays
in targeting cancer cells or efficiently
scanning freight for various security
irregularities.
