Beam Gas Curtain: a new instrument for LHC Run 3

A High-Luminosity LHC instrument known as the Beam Gas Curtain will be tested and start collecting data during Run 3

The Large Hadron Collider (LHC) will soon be restarted following its year-end technical stop. During this stop, new instruments were installed in the LHC tunnel, including the Beam Gas Curtain (BGC).

After ten years of development, the BGC will start taking data on the LHC’s proton beam this year during Run 3. It will provide precise 2D images of the alignment of the proton beams, making data taking more precise. The BGC instrument was designed for the high-luminosity upgrade of the LHC as part of a collaboration between CERN’s Beam Instrumentation group, Liverpool University, the Cockcroft Institute and GSI.
