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…
Effect of surface orientation on blistering of copper under high fluence keV hydrogen ion irradiation
A. Lopez-Cazalilla, C. Serafim, J. Kimari +6
Copper and hydrogen are among the most common elements that are widely used in industrial and fundamental research applications. Copper surfaces are often exposed to hydrogen in th…
Effects of H low beam irradiation and high field pulsing tests in different metals
C. Serafim, S. Calatroni, F. Djurabekov +7
This work studies the suitability of a set of different materials for manufacturing of more efficient and durable Radio-Frequency Quadrupole (RFQ) structures compared to that curre…
Interim report for the International Muon Collider Collaboration (IMCC)
C. Accettura, S. Adrian, R. Agarwal +383
The International Muon Collider Collaboration (IMCC) [1] was established in 2020 following the recommendations of the European Strategy for Particle Physics (ESPP) and the implemen…
Investigation on different materials after pulsed high field conditioning and low-energy H- irradiation
Catarina Serafim, R. Peacock, S. Calatroni +9
During operation, the radio-frequency quadrupole (RFQ) of the LINAC4 at CERN is exposed to high electric fields, which can lead to vacuum breakdown. It is also subject to beam loss…
