The Deep Electron FLASH Therapy facility / Rossi, Carlo (CERN) ; Malyzhenkov, Alexander (CERN) ; Grudiev, Alexej (CERN) ; Latina, Andrea (CERN) ; Frisch, Benjamin (CERN) ; Granados, Eduardo (CERN) ; Syratchev, Igor (CERN) ; Bourhis, Jean (Lausanne U.) ; Germond, Jean-François (Lausanne U.) ; Cravero, Jean-Marc (CERN) et al.
The “FLASH” effect is currently a topic of considerable interest in radio-oncology. We present the design of a novel VHEE linac, to be built and installed at CHUV (Lausanne), capable of producing electron beams which deliver radiation at dose rates and time scales consistent with the FLASH effect.

Conceptual design study for a dedicated low-energy diagnostics line at Linac3 / Bellodi, Giulia (CERN) ; Bodart, Dominique (CERN) ; Cravero, Jean-Marc (CERN) ; Etxebarria Erdoiza, Jone (CIEMAT - Centro de Investigaciones Energéticas Medioambientales y Tec. (ES)) ; Kuchler, Detlef (CERN) ; Mahner, Edgar (CERN) ; Roncarolo, Federico (CERN) ; Scrivens, Richard (CERN) ; Valerio Lizarraga, Cristhian Alfonso (Universidad Autonoma de Sinaloa (MX))
A low-energy diagnostics upgrade of Linac3 has been studied in the last couple of years to allow a more precise characterization of the beam properties at extraction from the source, currently impeded by a complete lack of measuring devices in the first ~6 m of the accelerator layout. [...]

Dead-Time influence on fast switching pulsed power converters design - A high current application for accelerator's magnets / Horrein, Ludovic (Lille U.) ; Cravero, Jean-Marc (CERN) ; Delarue, Philippe (Lille U.) ; Bouscayrol, Alain (Lille U.) ; Aguglia, Davide (CERN) ; Ortega-Perez, Carmen (Lille U.)
Dead-time in IGBT-based DC-DC power converters is a well-known issue that causes a limitation of the output voltage and the distortion of the output voltage and current. These distortions are more critical when the converter switching frequency increases and in applications requiring high di/dt. [...]

Hybrid capacitor discharge/switch-mode converter for pulsed applications: Topology and control design / Horrein, Ludovic (CERN) ; Cravero, Jean-Marc (CERN)
The paper objective is to propose an innovative power converter topology combining the advantages of capacitor discharge and switch-mode converters to generate half sinusoidal fast current pulses with high precision. The capacitor discharge operation mode of the converter allows the generation of current pulses with fast transient response and the switch-mode operation enables the control of the pulse shape with high precision.

Design Solutions for Compact High Current Pulse Transformers for Particle Accelerators’ Magnets Powering / Aguglia, Davide (CERN) ; Cravero, Jean-Marc (CERN) ; Rebeschini, Renato (TRASFOR S.A.) ; Iovieno, Salvatore (TRASFOR S.A.) ; Russo, Carlo (TRASFOR S.A.)
High current pulse transformers are widely used in particle accelerators for feeding pulsed magnets. Usually they need to be installed in very confined spaces, thus requiring compact design solutions. [...]
