Beam instabilities cover a wide range of effects in particle accelerators and they have been
the subjects of intense research for several decades. As the machines performance was …

Beam-induced heating of equipment can have several undesirable effects, including
rendering the equipment temporarily inoperative, equipment degradation and/or damage …

The i-pipe system is a peculiar structural health monitoring system, based on Fiber Bragg
Grating technology, installed on the central beam pipe of the compact Muon solenoid (CMS) …

The resistive wall impedance of a vacuum chamber with elliptic cross section is of particular
interest for circular particle accelerators as well as for undulators in free electron lasers. By …

Abstract The Large Hadron Collider (LHC) upgrade, which aims at reaching significantly
higher luminosities at the experiment sites, requires the existing injector chain to provide …

The LIU program at CERN is of paramount importance at international level. The program
foresees a significant upgrade of the LHC injector chain to increase the luminosity of the …

The need to push the LHC beyond its limits and increase the deliverable luminosity to the
experiments by about one order of magnitude has driven the ongoing injector and HL-LHC …

This paper explores the possibility of using electromagnetic metamaterials to synthesize an
equivalent structure that approaches superconductive-like properties, ie extremely high …

The CERN Proton Synchrotron Booster (PSB) has been known to suffer from horizontal
instabilities since its early operation in the 1970s. These instabilities appear at specific beam …

The performance of 25 ns beams in the LHC is strongly limited by the electron cloud. To
determine the amount of electron cloud in the cold sections of the machine, it is very …
