Direct large-area observation of subsurface plastic activity in conditioned copper electrodes
Yinon Ashkenazy, Inna Popov, Victoria M. Bjelland +2
High-field conditioning is the process by which radio-frequency structures in particle accelerators and other high-gradient devices reach their operating fields, yet the underlying…
Role of the Local Electric-Field in High-Field Conditioning of DC Electrodes:Numerical and Experimental Insights
Victoria Madeleine Bjelland, William Lee Millar, Morten Kildemo +1
Conditioning, the progressive increase of voltage-holding through the controlled application of fields, is an important and widely used process for bringing high-field and high-vol…
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…
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…
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…
RADES axion search results with a High-Temperature Superconducting cavity in an 11.7 T magnet
S. Ahyoune, A. Álvarez Melcón, S. Arguedas Cuendis +23
We describe the results of a haloscope axion search performed with an 11.7 T dipole magnet at CERN. The search used a custom-made radio-frequency cavity coated with high-temperatur…
