Tetrodes for Particle Accelerators

Tetrodes for Particle Accelerators

RF tetrodes for Particle Accelerators applications

The Thales’s ceramic-metal tetrode of coaxial structure is particularly suitable for use as an RF amplifier in particle accelerators. The technology of this tube has already been well proven and benefits from the company’s long experience in tetrodes.

Drawing on our long experience in tetrodes for accelerators, radars and broadcast transmitters, this tube features Thales’s patented Pyrobloc® grids and Hypervapotron™ cooling to allow a substantial safety margin of tolerable anode dissipation and Pyrobloc® grids for enhanced stability, reliability and operating life.

An associated cavity has been custom-designed to get the best performance from the tetrode, for scientific applications, such as in particle accelerators. For operation in different frequency ranges, other circuits are possible.

These products are designed, developed and manufactured at an ISO 9001/V2000 and ISO 14001 registered production site.
