Xsuite is a newly developed modular simulation package combining in single flexible and modern framework the capabilities of different tools at CERN past decades, notably Sixtrack, Sixtracklib, COMBI PyHEADTAIL. The suite consists set Python modules (Xobjects, Xpart, Xtrack, Xcoll, Xfields, Xdeps) that can be flexibly combined together with other accelerator-specific general-purpose python to study complex scenarios. code allows for symplectic modeling particle dynamics, effect synchrotron...
We present a laboratory study of photoelectric charging dust particles and their lofting on conducting surface in the presence external electric fields. Insulating with diameter <45 μm are dispersed exposed to ultraviolet (UV) light. In addition UV exposure, positive or negative field is applied. Independent orientation field, found be positively charged but different mechanisms. It shown that controls dynamics photoelectrons emitted from substrate surface. Distinctly results between...
Micrometer-sized dust particles present in the Large Hadron Collider (LHC) beam pipe are believed to have caused many thousands of sporadic loss events around LHC. These so-called unidentified falling objects (UFOs) been under continuous study since start high intensity operation LHC due their impact on availability: 139 dumps and 12 magnet quenches during Run II (2015--2018) alone. To mitigate UFOs future accelerators such as High Luminosity Future Circular Collider, it is fundamental...
The interaction of dust particles with the LHC proton beams accounts for a major fraction irregular beam loss events observed in physics operation. cease after few revolutions because expulsion from once they become ionized transverse tails. Despite transient nature these events, resulting losses can trigger aborts or provoke quenches superconducting magnets. In this paper, we study characteristics beam-dust particle interactions cryogenic arcs by reconstructing key observables like nuclear...
Dust grains interacting with the beam of particle accelerators are believed to be cause several detrimental effects such as losses, emittance growth, pressure bursts, and even quenches superconducting magnets. Experimental observations suggest that these positively charged in electron storage rings negatively Large Hadron Collider (LHC). In this paper, charging mechanisms for dust LHC discussed a possible explanation observed polarity is presented. Electron collection, secondary emission,...
An energy of 362 MJ is stored in each the two LHC proton beams for nominal beam parameters. This will be further increased to about 700 future high luminosity (HL-LHC) and uncontrolled losses represent a significant hazard integrity safe operation machine. In this paper, number failure mechanisms that can lead fast increase are analyzed. Most critical failures magnet protection system, namely quench heaters novel system called coupling-loss induced (CLIQ). important outcome has evaluated its...
