Comparison of Condor, Fci and Mafia Calculations for a 150mw S-band Klystron with Measurements

چکیده
To facilitate the design of high power klystrons an investigation into the reliability and accuracy of three modern particle-in-cell codes was performed. A 150MW S-band klystron for which measurements were available was used for this comparison. The field calculations of the particle-in-cell codes are based on a finite difference time domain scheme, and use a port approximation to speed up the convergence to steady state. However they differ in many details (eg. calculation of E, B or A; ; space charge correction; 2D or 3D modelling of output cavity).

An efficient finite difference time domain algorithm for band structure calculations of Phononic crystal
In this paper, a new algorithm for studying elastic wave propagation in the phononic crystals is presented. At first, the displacement-based forms of elastic wave equations are derived and then the forms are discretized using finite difference method. So the new algorithm is called the displacement-based finite difference time domain (DBFDTD). Three numerical examples are computed with this met...
متن کاملNUMERICAL DESIGN AND ANALYSIS OF A COMPACT T & s to TEol MODE TRANSDUCER
A high-power low-loss mode transducer design has been proposed to adapt the output of the X-Band klystron, WR.90 rectangular waveguide, to the input of the pulse compression system, SLED II, which utilizes overmoded circular waveguides operating in the low-loss TEol mode. This device is much more compact than the conventional Marie’ type mode converters. The device splits the incoming klystron ...

A new current structure for the fast traveling-wave 2.5MeV beam chopper in the front end of the Spallation Neutron Source (SNS) has been suggested in [1]. The structure is based on the meander-folded notched stripline with dielectric supports and separators. Its design has been optimized using electromagnetic 3-D modeling with the MAFIA code package to provide rise and fall times in the range o...

Self-association of alcohols; including ethanol, methanol, cyclopentanol and octanol in separate mixtures with inert solvents have been studied using FT-IR spectroscopy. Except for the band at 3640 cm–1 in the IR spectrum of the alcohols which is due to the monomer species, the presence of other bands in the region of stretching vibrational frequencies of OH (3100-3700 cm–1) are attributed to t...
متن کاملComparison of dosimetry parameters of two commercially available Iodine brachytherapy seeds using Monte Carlo calculations
Background: Iodine brachytherapy sources with low photon energies have been widely used in treating cancerous tumors. Dosimetric parameters of brachytherapy sources should be determined according to AAPM TG-43U1 recommendations before clinical use. Monte Carlo codes are reliable tools in calculation of these parameters for brachytherapy sources. Materials and Methods: Dosimetric param...
