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…
Fundamentals of Vacuum Breakdown in High-Field Systems
Walter Wuensch, Sergio Calatroni, Flyura Djurabekova +2
This review consolidates experimental, theoretical, and simulation work examining the behavior of high-field devices and the fundamental process of vacuum arc initiation, commonly…
Model for the Thermodynamics of Iron at High Pressures Near Melting
Rann Shikler, Noya Dimanstein Firman, Yinon Ashkenazy
The Fe pressure-temperature phase diagram and its melting line have a wide range of applications, including providing constraints for iron-core planetary models. We propose an equa…
Surface and sub-surface modifications of copper electrodes exposed to high-field conditioning at cryogenic temperatures
Marek Jacewicz, Iaroslava Profatilova, Piotr Szaniawski +4
In order to investigate the dependence of conditioning and field-holding on temperature, three pairs of copper electrodes underwent high voltage conditioning with direct current (D…
