Highly Accurate Frequency Calculations of Crab Cavities Using the Vorpal Computational Framework∗
We have applied the Werner-Cary method [J. Comp. Phys. 227, 5200-5214 (2008)] for extracting modes and mode frequencies from time-domain simulations of crab cavities, as are needed for the ILC and the beam delivery system of the LHC. This method for frequency extraction relies on a small number of simulations, and postprocessing using the SVD algorithm with Tikhonov regularization. The time-dom...
متن کاملBERLinPro 7-CELL SRF CAVITY OPTIMIZATION AND HOMs EXTERNAL QUALITY FACTORS ESTIMATION
The main scope of this work is the optimization of the Superconducting Radio Frequency (SRF) accelerating cavity design for the Berlin Energy Recovery Linac Project (BERLinPro). BERLinPro shall serve as a demonstrator for 100-mA-class Energy Recovery Liniac (ERL) with CW LINAC technology. High-current operation requires an effective damping of Higher-OrderModes (HOMs) of the 1.3 GHz main-linac ...
متن کاملOmega3P: A Parallel Finite-Element Eigenmode Analysis Code for Accelerator Cavities
Omega3P is a parallel eigenmode calculation code for accelerator cavities in frequency domain analysis using finite-element methods. In this report, we will present detailed finite-element formulations and resulting eigenvalue problems for lossless cavities, cavities with lossy materials, cavities with imperfectly conducting surfaces, and cavities with waveguide coupling. We will discuss the pa...

Side-coupled standing wave tubes in mode are widely used in the low-energy electron linear accelerator, due to high accelerating gradient and low sensitivity to construction tolerances. The use of various simulation software for designing these kinds of tubes is very common nowadays. In this paper, SUPERFISH code and COMSOL are used for designing the accelerating and coupling cavities for a 6 ...
متن کاملA new technique for bearing fault detection in the time-frequency domain
This paper presents a new Fast Kurtogram Method in the time-frequency domain using novel types of statistical features instead of the kurtosis. For this study, the problem of four classes for Bearing Fault Detection is investigated using various statistical features. This research is conducted in four stages. At first, the stability of each feature for each fault mode is investigated. Then, res...
