Free electron lasers using ‘beam by design’
New Journal of Physics, 2015 Several methods have been proposed in the literature to improve free electron laser output by transforming the electron phase-space before entering the FEL interaction region.

Vacuum birefringence at x-ray free-electron lasers
New Journal of Physics, 2021 We study the perspectives of measuring the phenomenon of vacuum birefringence predicted by quantum electrodynamics using an x-ray free-electron laser (XFEL) alone.

High average current electron guns for high-power free electron lasers
Physical Review Special Topics. Accelerators and Beams, 2011 High average power free-electron lasers (FELs) require high average current electron injectors capable of generating high quality, short duration electron bunches with a repetition rate equal to the frequency of the rf linac.

Recirculated Wave Undulators for Compact FELs
Applied Sciences, 2021 Particular schemes of Free Electron Lasers (FELs) are designed to exploit wave undulators. We consider a system employing a recirculated electromagnetic undulator provided by a high-power laser in a resonator cavity.

Limitations of electron beam conditioning for free-electron lasers
Physical Review Special Topics. Accelerators and Beams, 2003 Several ideas have been proposed to “condition” an electron beam prior to the undulator of a free-electron laser (FEL) by increasing each particle’s energy in proportion to the square of its transverse betatron amplitude.

Molecular Oncology, EarlyView.Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Pulse Duration of Seeded Free-Electron Lasers
Physical Review X, 2017 The pulse duration, and, more generally, the temporal intensity profile of free-electron laser (FEL) pulses, is of utmost importance for exploring the new perspectives offered by FELs; it is a nontrivial experimental parameter that needs to be ...

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
