We present PARSEC, a 3D parallel self-consistent particle tracking program which allows electron-cloud calculations in arbitrary external fields. The program is based on an general particle tracking framework called GenTrackE [5]. The Lorentz force equation is integrated with time as the independent variable. A 3D parallel Multigrid solver computes the electric field for the drive beam in the b...

Abstract In this paper, a detailed 3-D analysis of the electron beam shape at target plane high power (60 kW, 60 kV, 1 A) 270 0 -bent indirectly heated cathode-based gun has been successfully carried out. This work will help analyse individual trajectories in actual to ensure optimum bending and focusing plane. Moreover, due presence an additional electrode i.e., filament which is resistively s...

The two main functions of the NLC extraction line include: 1) transmission of the outgoing disrupted beam and secondary particles to the dump with minimal losses; and 2) beam diagnostics and control. In this report, we describe the extraction line optics, present the results of tracking studies, and discuss the extraction line instrumentation. Presented at the 1999 IEEE Particle Accelerator Con...

Accsim is a synchrotron/storage-ring tracking and simulation program that was originally written to simulate chargeexchange injection and accumulation of an intense proton beam in a KAON factory accumulator ring. It has subsequently been developed and used for other injection studies and for applications such as the optimization of collimation systems. The code performs basic six-dimensional tr...

The injection line and main ring lattice designs for the University of Maryland Electron Ring [1] have been studied numerically. Possible injection systems were designed using a fitting algorithm based on a set of generalized rms-envelope equations that include the effects of space charge and beam momentum dispersion. The beam dynamics of the injection into and through the periodical ring struc...

This paper presents a novel approach to measuring and mapping shape and motion of the water surface. The approach combines and borrows from existing techniques, such as stereo imaging shape recognition and tracking, infrared (IR) laser marking and thermography, and particle image velocimetry. The system consists of a high power IR laser beam controlled by a programmable marking head and two IR ...

Abstract Purpose The physics design of the High Energy Photon Source (HEPS) was finished after many times iteration. Hereby, typical equilibrium electron beam parameters corresponding to proposed two baseline operation modes in HEPS are presented. Methods To compute beam, lattice parameters, RF and insertion devices (IDs) were determined first. Furthermore, it is more precise use full-current e...

The NOMAD experiment was designed to search for ντ appearance from neutrino oscillations in the CERN wide-band neutrino beam produced by the 450 GeV proton synchrotron. The single-particle reconstruction and lepton identification capability of the NOMAD detector allowed the search for ντ appearance in most of the leptonic and hadronic τ decay channels [1] and also to look for νμ → νe oscillatio...
