We present an overview of accelerator-based searches for magnetic monopoles and we show why such searches are important for modern particle physics. Possible properties of monopoles are reviewed as well as experimental methods used in the search for them at accelerators. Two types of experimental methods, direct and indirect are discussed. Finally, we describe proposed magnetic monopole search ...

The paper discusses an advanced level information system to support educational, research and scientific activities of the Department"Electrophysical Facilities"(DEF) of the National Research Nuclear University"MEPhI"(NRNU MEPhI), which is used for training of specialists of the course"Physics of Charged Particle Beams and Accelerator Technology".

Corrugated, hydrophilic particles with diameters between 30 and 150 microm are found to cause cavitation inception at their surfaces when they are exposed to a short, intensive tensile stress wave. The growing cavity accelerates the particle into translatory motion until the tensile stress decreases, and subsequently the particle separates from the cavity. The cavity growth and particle detachm...

We describe a transparent dielectric grating accelerator structure that is designed for ultrashort laser pulse operation. The structure is based on the principle of periodic field reversal to achieve phase synchronicity for relativistic particles; however, to preserve ultrashort pulse operation it does not resonate the laser field in the vacuum channel. The geometry of the structure appears wel...

A mathematical proof of a theorem concerning the flux density of particles at any point interior to a simple closed convex surface in which the surface emits such particles uniformly and isotropically is presented. The relationship of this theorem, which is of rather general validity, to related observations of other workers is discussed. The ramifications of the theorem are considered with par...

We discuss techniques for Model-Independent Analysis (MIA) of a beamline using correlation matrices of physical variables and Singular Value Decomposition (SVD) of a beamline BPM matrix. The beamline matrix is formed from BPM readings for a large number of pulses. The method has been applied to the Linear Accelerator of the SLAC Linear Collider (SLC). submitted to Sixth European Particle Accele...

Tuning particle accelerators is time consuming and expensive, with a number of inherently non-linear interactions between system components. Conventional control methods have not been successful in this domain, and the result is constant and expensive monitoring of the systems by human operators. This is particularly true for the start-up and conditioning phase after a maintenance period or an ...

At SLAC, we are pursuing the design of a Next Linear Collider (NLC) which would begin with a center-of-mass energy of 0.5 TeV, and would be upgradable to 1.0 TeV and beyond [1]. To achieve this high energy, for the past several years we have been working on the development of a high-gradient 11.4-GHz (X-band) linear accelerator for the main linac of the collider. In this paper, we present the s...

The calculation of space charge effects in linear accelerators is an important prerequisite to understand the interaction between charged particles and the surrounding environment. These calculations should be as efficient as possible. In this work we explore the suitability of the CrouzeixRaviart Finite Element Method for the computation of the self-field of an electron bunch.
