Pioneering laser technology experiment completed at Dundee

Professor Amin Abdolvand's pioneering laser technology, which could aid future experimentation at CERN's Large Hadron Collider (LHC), has been used successfully in an experiment which explored its interaction with samples of the cold bore experiment (COLDEX) beam screens used in the LHC.

The research team at the University of Dundee used the COLDEX beam screens, which had been provided by CERN, in order to determine laser parameters required to achieve a Secondary Electron Yield (SEY) value of <1 at cryogenic temperatures (1.9 degrees Kelvin or -271.3°C). Since January 2017, nine COLDEX sections have been treated at labs at the University of Dundee and returned to CERN for further testing from April 2017.

Here is a video of the laser experiment in action:
