TL;DR: Time-of-Aight signals and azimuthal distributions from the gas-ionization moni-tor agreed well with theoretical expectations and were used to reduce beam tails.
Journal ArticleDOI
Model-Independent Beam Dynamics Analysis

TL;DR: Using a singular value decomposition of a beam line matrix, composed of many beam position measurements for a large number of pulses, together with the measurement of pulse-by-pulse beam properties or machine attributes, the contributions of each variable to the beam centroid motion can be identified with a greatly improved resolution as mentioned in this paper.
Proceedings ArticleDOI
LEGO: a modular accelerator design code
TL;DR: In this article, an object-oriented accelerator design code has been designed and implemented in a simple and modular fashion, which contains all major features of its predecessors: TRACY and DESPOT.
Proceedings ArticleDOI

TL;DR: In this article, a new type of damped detuned structure with optimized round-shaped cavities (RDDS) was proposed for X-band accelerator structures for the JLC/NLC linear collider.
Proceedings ArticleDOI
A multi-moded rf delay line distribution system for the next linear collider
Sami Tantawi,Gordon Bowden,Z.D. Farkas,J. Irwin,Kwok Ko,N.M. Kroll,T.L. Lavine,Z. Li,Roderick J. Loewen,Robert J. Miller,C. Nantista,Ronald D. Ruth,Jeffrey Rifkin,Arnold Vlieks,Perry B. Wilson,Chris Adolphsen,J.W. Wang +16 more
TL;DR: The Delay Line Distribution System (DLDS) as discussed by the authors is an alternative to conventional pulse compression, which enhances the peak power of rf sources while matching the long pulse of those sources to the shorter filling time of accelerator structures.
