Decommissioning and Post-Irradiation Examination of the LHC Beam Dumps
N. Solieri, A. Lund, A. -P. Bernardes +21
The LHC beam dumps are responsible for the safe absorption of the Large Hadron Collider (LHC) particle beams. In 2018, the two 6.4-tonne beam dumps that had been in operation since…
Plasma treated metals after H- irradiation and its effect on vacuum breakdown behaviour
C. Serafim, S. Calatroni, F. Djurabekova +9
Vacuum breakdown in accelerator structures is a critical challenge that occurs under high electric fields. In environments subjected to hydrogen ion irradiation or high beam losses…
Characterising the Surface Resistance of Laser-Treated LHC Beam Screens with the Shielded Pair Method
P. KrkotiÄ, E. Bez, K. Brunner +6
The presence of strong electron clouds in the quadrupole magnetic field regions of the Large Hadron Collider (LHC) leads to considerable heating that poses challenges for the cryog…
Influence of nanoparticulates and microgrooves on the secondary electron yield and electrical resistance of laser-treated copper surfaces
P. KrkotiÄ, T. Madarász, C. Serafim +4
Laser surface structuring has proven to be an effective technique for achieving a copper surface with secondary electron yield (SEY) values close to or below unity. However, the at…
