High‐Entropy Magnetism of Murunskite

Henrik Moodysson Rønnow, Ivica Zivkovic, Thomas La Grange, Davor Tolj, Rongrong Cai

Murunskite (K 2 FeCu 3 S 4 ) bridges the two known families of high‐temperature superconductors, cuprates and iron‐pnictides, structurally and electronically. Like these families, murunskite exhibits an antiferromagnetic (AF)‐like response with an ordered ...

Studies of crystal collimation for heavy ion operation at the LHC

Rongrong Cai

At CERN's Large Hadron Collider (LHC), proton and heavy-ion beams are accelerated to multi-TeV energies to be collided for the needs of the scientific community around the world. The total stored beam energy of tens to hundreds ofMJ creates potential threa ...

Pinpointing the thermal history of lunar basaltic meteorites in a nutshell

Cyril Cayron, Philippe Gillet, Rongrong Cai, Arthur Brian Aebersold

Native metals of igneous origin are recognized as one of the distinctive features of basalts from the Moon. Our study demonstrates that the tiny Fe-Ni metal blebs nucleated from lunar magma exhibit unanticipated, nutshell-like, crystallographic microstruct ...

Characterization of bent crystals for beam collimation with 6.8 TeV proton beams at the LHC

Rongrong Cai

The concept of crystal collimation exploits the peculiar properties of crystalline materials to deflect highenergy beam particles at angles orders of magnitude larger than what can be achieved with scattering by conventional materials used as primary colli ...

Crystal collimation of heavy-ion beams at the Large Hadron Collider

Rongrong Cai

An important upgrade has been deployed for the collimation system of the Large Hadron Collider (LHC) for lead-ion beams that are already planned to reach their high-luminosity target intensity upgrade in the ongoing LHC Run 3 (2022–2026). While certain eff ...

Simulation framework and measurements of crystal collimation of proton beams at the Large Hadron Collider

Mike Seidel, Rongrong Cai

Thanks to its versatility in deploying large kicks with high efficiency, crystal channeling is being integrated more and more into modern particle accelerators. For example, at the CERN Large Hadron Collider, crystals are used, or planned to be used for co ...

Power Deposition Studies for Crystal-Based Heavy Ion Collimation in the LHC

Rongrong Cai

The LHC heavy-ion program with 208Pb⁸²⁺ beams is foreseen to benefit from a significant intensity upgrade in 2022. A performance limitation may arise from ion fragments scattered out of the collimators in the betatron cleaning insertion, which risk quenchi ...

Benchmarks of Energy Deposition Studies for Heavy-Ion Collimation Losses at the LHC

Rongrong Cai

During some periods in its second physics run (2015-2018), the LHC has been operated with 208Pb⁸²⁺ ion beams at an energy of 6.37 ZTeV. The LHC is equipped with a betatron collimation system, which intercepts the transverse beam halo and protects sensitive ...
