MC04: Transverse Profile and Emittance Monitors

Invited Oral Presentation

The high intensity and wide energy range of the Large Hadron Collider (LHC), further extended by its high-luminosity upgrade, set great challenges on beam diagnostics. The Beam Gas Curtain (BGC), installed on Beam 1 in 2023, addresses these challenges with a non-invasive profile monitor exploiting the fluorescence induced by the beam in a thin supersonic gas curtain. This contribution reviews...

MC04: Transverse Profile and Emittance Monitors

Contributed Oral Presentation

High-luminosity electron–positron colliders such as SuperKEKB operate with high bunch currents and a large number of bunches in collision. Under these conditions, various beam instabilities can arise and limit beam performance. Investigating such phenomena requires diagnostic instruments capable of resolving beam properties on a bunch-by-bunch timescale. In particular, identifying...
