As part of the study on using structured laser light for alignment, an innovative technique is proposed for generating symmetrical pseudo-non-diffracting layers of caustic optical beams, known as Layer Beams (LB). The state of the art for producing similar beams consists of using spatial light modulators. Our approach is based on the design of a generator with a specific arrangement of...
Alignment of superconducting cavities is a critical concern for the China Spallation Neutron Source Phase II (CSNS II) linac. To measure cavity displacement during the cooling process to liquid helium temperature, a new laser-based Poisson Spot Monitor (PSM) system was introduced. This system utilizes the diffraction spot captured on a CMOS camera when a parallel laser beam passes through a...
The High-Luminosity Large Hadron Collider (HL-LHC) project at CERN aims to enhance the LHC's performance and expand its potential for discoveries beyond 2029. New components will be installed within the 220 meters before the collision points of the ATLAS and CMS experiments, including 16 NB3Sn quadrupoles to focus the beam before collision and 8 radio frequency crab cavities to allow beam...
