Dynamic Beam-RF PIC Analysis

Hardware Design
CCR engineers and scientists are highly skilled in the development and design of a wide variety of high power microwave, millimeter wave and THz devices and components. These include:

Electron guns for linear beam devices
Circuits for traveling-wave tubes, klystrons, gyrotrons, and klystrodes
Standard and multi-stage depressed collectors
RF windows
Mode converters
Mode filters
Custom Input/Output couplers
Magnetic/Electrostatic beam focusing
Custom mechanical design and packaging

CCR personnel have designed klystron and gyrotron RF windows at a wide variety of frequencies and power levels. The maximum peak power level achieved to date for a klystron window exceeds 60 MW at X-Band. Maximum average power achieved exceeds 500 kW CW at 110 GHz. CCR personnel have experience with a wide variety of window materials, including BeO, AL-995, and single crystal sapphire in both fundamental and overmoded window configurations.

Software Development
CCR programmers are experienced in a wide variety of computer languages, including FORTRAN, C, C++, Bourne and C shell scripts, X/Motif, python, Tcl, Tk, Visual Basic, SQL, and AutoLISP. Database experience includes HP-ADDBASE, Recital, Paradox, Informix, and SQL. Operating system experience includes SunOS, Solaris, DEC Ultrix, DGUX, HPUX, BSD and ATT System V UNIX, VAX/VMS, DOS, Microsoft Windows and NT. CCR programmers are experienced in object oriented programming techniques.

Programs developed include graphical user interfaces for electromagnetic and particle simulation codes for the microwave tube community. Computational codes include particle simulation codes and small signal and large signal circuit modeling programs. A number of RF codes have been developed, including Cascade.

Thermomechanical Analysis
CCR provides finite element thermomechanical analysis for a wide variety of microwave and millimeter wave devices. Both steady-state and transient analysis can be performed to determine stresses and the effects of thermal cycling, including creep and yield. Devices that can be modeled include cathodes, cathode support structures, electron guns, collectors, and RF windows. CCR uses the computer codes Marc/Mentat and COSMOS for thermomechanical finite element analysis.

Electromagnetic Analysis
CCR personnel are skilled in the use of Ansoft's Maxwell; HFSS products; CST's Microwave Studio and MAFIA (MAxwell's Equations Solved by the Finite Integration Algorithm); and the Poisson Group of codes. In addition to CCR's own finite element particle program under development, personnel have access to finite difference programs with fixed and conformal, variable mesh solvers. These codes are used in the design of RF circuits, couplers, electron guns and particle focusing systems utilizing solenoids, permanent magnets, and nonlinear magnetic materials.

CAD & Design Services
CCR's principle designer has more than 40 years of experience in the design of microwave tubes and components, including klystrons, traveling wave tubes, magnetron injection guns, gridded and bonded-grid electron guns, gyro-amplifier tubes and gyrotrons, RF windows, and waterloads.

Dynamic Beam-RF PIC Analysis
CCR personnel are very skilled in the use of PIC code 2D/3D MAGIC. It is used to accurately estimate RF devices’ performances such as efficiency, gain and bandwidth and provide time-domain diagnostic of how an electron beam interacts with RF field for a wide variety of vacuum tube devices.
