KlyC: 1.5-D large-signal simulation code for klystrons / Cai, Jinchi (CERN) ; Syratchev, Igor (CERN)
The High Efficiency International Klystron Activity (HEIKA) was initiated at CERN in 2014 to evaluate and develop new klystron bunching technologies for high-efficiency klystrons in application to the large-scale scientific projects such as the Compact Linear Collider (CLIC) and the Future Circular Collider (FCC). The success of such development strongly depends on the availability of the specialized klystron computer codes. [...]

Experimental and Numerical Investigation on Losses in Electrodynamic Transients in a Nb$_{3}$Sn Prototype Racetrack Coil / Breschi, M (U. Bologna (main)) ; Macchiagodena, A (U. Bologna (main)) ; Ribani, P L (U. Bologna (main)) ; Bellina, F (U. Udine (main)) ; Stacchi, F (U. Udine (main)) ; Izquierdo Bermudez, S (CERN) ; Bajas, H (CERN)
The detailed knowledge of the current and losses distribution during the electrodynamic transients is of great importance for the design of superconducting accelerator magnets made of Rutherford cable. On the one hand, the current distribution affects the field harmonics generated by the superconducting magnet; on the other hand, losses strongly affect the design of the cryogenic system and may jeopardise the magnet stability.
