Bridge12 develops electron guns for a variety of applications, including microwave tubes, X-ray sources, accelerator applications, and more. We can provide prototype electron guns based on your electron beam requirements, including a full-physics and electrical design. We also work with customers from research laboratories and universities who want an implementation of their electrical design, which is often provided as electrode shapes. We utilize a combination of electrostatic and magnetic focusing systems to achieve the right beam parameters for your requirement.
Currently, electron guns for VEDs are largely built on a one-off basis, resulting in costly designs and long lead times. Furthermore, there is only a very small selection of vendors that can fabricate these devices. Our experienced team of scientists and engineers at Bridge12 has streamlined the design process significantly by using state-of-the-art design and fabrication methods. We utilize industry bench-marked tools for electromagnetic and mechanical finite element-based simulations, optimize electrode poles, and to perform a complete thermal analysis. Our electron guns are fabricated in-house, where we have special facilities for testing dielectric strength, DC emissions, and customized performance testing. All of our electron guns are baked-out at temperatures of up to 450 °C on our in-house exhaust station, as necessary for industrial applications.
Bridge12 specializes in Magnetron Injection Guns (MIGs) for gyrotrons, linear or sheet beam guns for traveling wave tubes (TWTs), high power microwave (HPM) devices, and accelerator systems. Some of the recent electron guns manufactured by Bridge12 for our customers include a 65 kV, 7 A Magnetron Injection Gun for a millimeter wave gyrotron, a 20 kV, 0.25 A gun for terahertz gyrotron and a 12 kV, 40 mA sheet beam electron gun for use in a terahertz traveling-wave-tube.
Bridge12 can verify customer-provided electrical designs and optimize the design for mechanical implementation, or we can design the magnetic focusing system necessary for beam transport to match customer provided mechanical constraints. We develop one-off prototypes as well as models equipped for serial production. The interfaces can be either weld flanges or demountable CF flanges. An integrated and isolated ion pump can be provided for long term storage of the gun assembly or for use during operation.
