The recently installed internal gas target at LHCb presents exceptional opportunities for an
extensive physics program for heavy-ion, hadron, spin, and astroparticle physics. A storage …

Tsinghua University is currently developing a very-high-frequency electron gun that
operates in continuous-wave (cw) mode at 216.667 MHz. This gun will serve as the beam …

In this study, COMSOL Multiphysics is used in the numerical analysis of a neutral gas in the
divertor pumping system of the China Fusion Engineering Test Reactor (CFETR). The slip …

The cryogenic vacuum system is an important subsystem of Comprehensive Research
Facility for Fusion Technology Negative Neutral Beam Injector, which provides vacuum …

Ions are produced in an accelerator when the beam ionizes residual gas inside the vacuum
chamber. If the beam is negatively charged, ions can become trapped in the beams …

Modern particle accelerators, synchrotrons, and other machines requiring UHV frequently
make use of NEG coatings to achieve low pressures and resulting high beam stability and …

Stripping units take a key role in the neutral particle analyzer (NPA). A renovated gas-
stripping unit was constructed for the newly designed E//B NPA. Using\({\textrm {H}} _2\) as …

Cryosorption pumps create a vacuum by adsorbing gas at low temperature through porous
solid adsorbents. The transmission probability of gas molecules and heat loads of …

The vacuum vessel of fusion devices, equipped with an array of external ports characterized
by intricate flange connections and welding joints, inherently carries a notable risk of …

EuroCirCol is a conceptual design study of a post-LHC, Future Circular Hadron Collider
(FCC-hh) with 50 TeV of beam energy and 100 km long, which aims to expand the current …
