Low-cost THz electro-optic detection in single-shot and at MHz acquisition rates, using photonic time-stretch

Christelle Hanoun, C. Szwaj, Eléonore Roussel, S. Bielawski et autres

A range of applications requires THz pulses to be recorded in one shot, and at high acquisition rates. This concerns TDS of rapidly evolving samples, and diagnostics in accelerator-based light sources (synchrotron radiation facilities and free-electron lasers). Although demonstrations of MHz+ single-shot …

Cost-effective time-stretch terahertz recorders, using 1550 nm probes

Christelle Hanoun, Eléonore Roussel, C. Szwaj, Clément Evain et autres

Time-stretch electro-optic detection allows THz waveforms to be recorded in single-shot, up to megahertz acquisition rates. This capability is required in accelerator physics, and also opens new applications in table-top THz time-domain spectroscopy. However, the technique has also been notoriously known for …

A Low-emittance Booster Lattice Design for the SOLEIL Upgrade

Marie-Agnès Tordeux, Zhenghe Bai, Gangwen Liu, Alexandre Loulergue et autres

The SOLEIL storage ring upgrade will require an injected beam with small transverse and longitudinal sizes. To meet this requirement, the present booster also needs to be upgraded, aiming to reduce the emittance below 10 nm·rad. A multi-bend achromat lattice is designed …
