Accelerator physics beyond the Lhc is expected to provide precision in the study of new physics processes which the Lhc may have already unveiled and to extend the high energy frontier beyond its reach, in the multi-TeV domain. In this paper I review the anticipated needs in terms of particle identification of this physics program in relation to the experimental conditions.

commbsioning particle beam lines in nsually a very t imeconsuming and labor-intensive task for accelerator physicists. To aid in commissioning, we developed a model-based expert system that identifies error-free regions, w well a~ localiiing beam line errors. Thii paper will give examples of the use of our try&em for the SLC commissioning.

We describe a hybrid data-representation and rendering technique for visualizing large-scale particle data generated from numerical modeling of beam dynamics. The basis of the technique is mixing volume rendering and point rendering according to particle density distribution, visibility, and the user’s instruction. A hierarchical representation of the data is created on a parallel computer, all...

Abstract. A beam of protons is produced by a linear charged particle accelerator, then focused through the use of successive quadrupoles. The initial state of the beam is unknown, in terms of particle position and momentum. Wire scans provide the only available data on the current state of the beam as it passes through and beyond the focusing region; the goal is to infer the initial state from ...

The current focus of the CERN program is the Large Hadron Collider (LHC), however, CERN is engaged in long baseline neutrino physics with the CNGS project and supports T2K as recognized CERN RE13, and for good reasons: a number of observed phenomena in high-energy physics and cosmology lack their resolution within the Standard Model of particle physics; these puzzles include the origin of neutr...

Reliable and precise methods for non-invasive diagnostics of sub-picosecond electron bunches are required for new accelerator facilities (FEL, LWFA, et al.). Measurements of spectral characteristics of coherent radiation generated by such bunches using interferometer allow to determine a bunch length [1]. Here we present a compare experimental study between the measurement from the double diffr...

Fermilab carries out an extensive program of accelerator-based high energy particle physics research at the Intensity Frontier that relies on the operation of 8 GeV and 120 GeV proton beamlines for a n umber of fixed target experiments. Routine operation with a world-record 700kW of average 120 GeV beam power on the neutrino target was achieved in 2017 as the result of the Proton Improvement Pl...

Quantum Mechanics states a particle can behave as either a particle or a wave. Since sound can be described as a superposition of frequencies, a metaphor between ‘particle physics’ and sound synthesis is inspired. This metaphor is quantitatively developed here, suggested initially from a few similarities between the two disparate domains. Its practical use for music composition is discussed. Wi...

WOLFGANG K. H. PANOFSKY Stanford Linear Accelerator Center Stanford University, Stanford, California 94309 ABSTRACT This paper reviews some key experiment,s of the past in which the same basic physical processes are attacked both through lepton-photon interactions and by using hadron machines as primary tools. Not surprisingly, it is conrludeh that the basic distinction between lepion-photon ph...

We present a portable system for intelligent control of particle accelerators. This system is based on a hierarchical distributed architecture. At the lowest level, a physical access layer provides an object-oriented abstraction of the target system. A series of intermediate layers implement general algorithms for control, optimization, data interpretation, and diagnosis. Decision making and pl...
