CCR’s products are primarily used in high energy physics and fusion research. Multiple beam RF sources are being developed for ion and muon colliders. Gyrotron related products are principally targeted for fusion energy research; however a permanent magnet gyrotron for the Active Denial System is nearing completion for the U.S. Navy and U.S. Air Force. CCR also developed and delivered advanced high current density cathodes for the DARPA HiFIVE program. This program is developing a 50 W RF source at 220 GHz. CCR is developing a 650 GHz RF source for the U.S. Air Force and National Aeronautics and Space Administration (NASA). CCR recently delivered a 90 kV electron gun for a free electron laser system.
Key products include a 90 kV gridded electron gun for free electron lasers, high current density cathodes, high power microwave and millimeter wave windows, and high power loads for MW CW RF sources above 100 GHz. CCR also produced a 10 MW, pulsed gyroklystron at W-Band.
CCR’s Product Groups
Calabazas Creek Research, Inc. has designed RF windows from L-Band to W-Band at power levels from a few watts to more than 100 MW. Recent designs include a TE01 window for 200 MW pulsed operation at 1.3 GHz and a 100 MW window at X-Band using single crystal sapphire.
CCR is involved in RF source development from 350 MHz to 2 THz at power levels from milliwatts to Megawatts of output power.
CCR’s staff has several decades of experience in the design and modeling of electrostatic, magnetostatic and electrodynamic devices with a particular emphasis on electron guns for a variety of applications. Codes used include Maxwell 2- and 3D, TRAK and EGUN (2 charged particle dynamics), OmniTrak (3D charged particle dynamics), MAGIC (3D PIC), and Beam Optics Analyzer. The combination of the large suite of codes in conjunction with experience with many types of electron guns allows CCR to model customers’ existing designs or produce new designs quickly and efficiently.
The high power waterloads are available for RF power levels up to 1.5 MW CW. The current device is designed for operation between 70 GHz and 170 GHz, though lower frequency devices can be designed with minimal additional cost.
Calabazas Creek Research, Inc. designs mode converters and tapers for a number of applications, including accelerator systems, Radar, and fusion devices. Recent converters include:
- TE11 to TE01 Mode Converter
- TE11 to TE12 Mode Converter
- TE01 to 80% TE01 and 20% TE02 for transmission across waveguide gaps
Tapers are designed to maximize mode purity while minimizing length. Nonlinear tapers are designed using the optimizing feature in Cascade to achieve mode purities exceeding 98%.
