Gyrotrons

Gyrotrons are microwave tubes that can efficiently generate millimeter and terahertz waves at powers up to a few MW. They have found application in areas such as DNP-NMR spectroscopy, material processing, plasma heating, and plasma diagnostics. Bridge12 is the only manufacturer that offers turn-key gyrotron systems equipped with a power supply, superconducting magnet, graphical user interface (GUI) based control system, and other accessories.
Gyrotrons with Superconducting Magnets

Gyrotrons with Superconducting Magnets

We develop a range of gyrotron systems for use in Dynamic Nuclear Polarization enhanced Nuclear Mangetic Resonance (DNP-NMR) spectroscopy, plasma heating and diagnostics and material processing. These gyrotrons range in power from a few watts to hundreds of kW. A 10 kW, 170 GHz continuous wave gyrotron tube is shown on the right. This device operates in a 6.3 T superconducting magnet.

Gyrotrons with Permanent Magnets

Gyrotrons with Permanent Magnets

We have developed gyrotrons with permanent magnets for special applications. A 90 kW long pulse W-band gyrotron operating in the second harmonic with a hybrid (electromagnet and a permanent magnet) is shown on the left.

Tunable Gyrotrons for DNP-NMR

Tunable Gyrotrons for DNP-NMR

Unlike standard fixed frequency gyrotrons available in the market, Bridge12’s gyrotrons are designed to be tunable to allow users to conduct versatile DNP-NMR experiments like measuring the enhancement field profile to determine the frequency for maximum enhancement and also to work with a range of polarizing agents. DNP-NMR systems equipped with tunable gyrotrons do not need expensive sweep coil in the NMR magnet. This reduces cost as well as provides the ability to upgrade existing NMR setups without having the need to replace the NMR magnet. Typical frequency tuning characteristics of our 395 GHz gyrotron is shown on the right. An additional 0.35 GHz tuning is available by integrated temperature control
