RF controls based on carrier suppression detection with attosecond resolution

Julien Branlard, Matthias Hoffmann, Uroš Mavrič, Heinrich Pryschelski et autres

This paper presents a radio frequency (rf) control system with attosecond resolution based on a carrier suppression interferometer operating a superconducting cavity at the Cryo Module Test Bench (CMTB). This novel application of the carrier suppression detector extends conventional heterodyne methods and …

Phase Noise Measurements for L-Band Applications at Attosecond Resolution

Louise Springer, Frank Ludwig, Uroš Mavrič, Volodymyr Vasylyuk et autres

This article summarizes theoretical and technical limitations when applying carrier-suppression interferometer (CSI) methods for precision phase-noise measurements at attosecond resolution. The CSI setup reported here outperforms conventional down-mixing methods by more than two orders of magnitude. For phase noise measurements at 1.3 …

Compact Single-Shot Electro-Optic Detection System for THz Pulses with Femtosecond Time Resolution at MHz Repetition Rates

B. Steffen, Lorenzo Rota, M. Caselle, M. Felber et autres

Electro-optical detection has proven to be a valuable technique to study temporal profiles of THz pulses with pulse durations down to femtoseconds. As the Coulomb field around a relativistic electron bunch resembles the current profile, electro-optical detection can be exploited for non-invasive …

RF Controls Towards Femtosecond and Attosecond Precision

Frank Ludwig, Julien Branlard, Łukasz Butkowski, Marie Kristin Czwalinna et autres

In the past two decades, RF controls have improved by two orders in magnitude achieving meanwhile sub-10 fs phase stabilities and 10⁻⁴ amplitude precision. Advances are through improved field detection methods and massive usage of digital signal procession on very powerful field …

RF Electronics for the Measurement of Beam Induced Higher Order Modes (HOM) Implemented in the MicroTCA.4 Form Factor

Szymon Jabłoński, Uroš Mavrič, H. Schlarb

Higher order modes (HOM) excited in RF accelerating cavities by a particle beam can be used for electron beam diagnostics. Phase of a monopole HOM provides information about the beam phase relative to the externally induced RF field in a cavity (BPhM) …
