DAΦNE -2023/24 Activity report
C. Milardi, D. Alesini, M. Behtouei +27
The DAΦNE operations during the last year have been devoted to deliver a statistically significant data sample to perform the first-ever measurement of kaonic deuterium X-ray trans…
Mitigation of the Microbunching Instability Through Transverse Landau Damping
A. D. Brynes, G. Perosa, C. -Y. Tsai +14
The microbunching instability has been a long-standing issue for high-brightness free-electron lasers (FELs), and is a significant show-stopper to achieving full longitudinal coher…
FEL stochastic spectroscopy revealing silicon bond softening dynamics
Dario De Angelis, Emiliano Principi, Filippo Bencivenga +20
Time-resolved X-ray Emission/Absorption Spectroscopy (Tr-XES/XAS) is an informative experimental tool sensitive to electronic dynamics in materials, widely exploited in diverse res…
Extreme ultraviolet wave packet interferometry of the autoionizing HeNe dimer
Daniel Uhl, Andreas Wituschek, Rupert Michiels +24
Femtosecond extreme ultraviolet wave packet interferometry (XUV-WPI) was applied to study resonant inter-atomic Coulombic decay (ICD) in the HeNe dimer. The high demands on phase s…
Characterization of soft X-ray echo-enabled harmonic generation free-electron laser pulses in the presence of incoherent energy modulations
N. S. Mirian, G. Perosa, E. Hemsing +14
Echo-enabled harmonic generation free-electron lasers (EEHG FELs) are promising candidates to produce fully coherent soft x-ray pulses by virtue of efficient high harmonic frequenc…
Attosecond Pulse-shaping using a seeded free-electron laser
Praveen Kumar Maroju, Cesare Grazioli, Michele Di Fraia +41
Attosecond pulses are fundamental for the investigation of valence and core-electron dynamics on their natural timescale. At present the reproducible generation and characterisatio…
Microbunching Instability Characterisation via Temporally Modulated Laser Pulses
A. D. Brynes, I. Akkermans, E. Allaria +19
High-brightness electron bunches, such as those generated and accelerated in free-electron lasers (FELs), can develop small-scale structure in the longitudinal phase space. This ca…
Terahertz tuning of Dirac plasmons in BiSe Topological Insulator
Paola Di Pietro, Nidhi Adhlakha, Federica Piccirilli +7
Light can be strongly confined in sub-wavelength spatial regions through the interaction with plasmons, the collective electronic modes appearing in metals and semiconductors. This…
A new method for measuring angle-resolved phases in photoemission
Daehyun You, Kiyoshi Ueda, Elena V. Gryzlova +33
Quantum mechanically, photoionization can be fully described by the complex photoionization amplitudes that describe the transition between the ground state and the continuum state…
Tracking Attosecond Electronic Coherences Using Phase-Manipulated Extreme Ultraviolet Pulses
Andreas Wituschek, Lukas Bruder, Enrico Allaria +31
The recent development of ultrafast extreme ultraviolet (XUV) coherent light sources bears great potential for a better understanding of the structure and dynamics of matter. Promi…
Beyond the Limits of 1D Coherent Synchrotron Radiation
A. D. Brynes, P. Smorenburg, I. Akkermans +21
An understanding of collective effects is of fundamental importance for the design and optimisation of the performance of modern accelerators. In particular, the design of an accel…
Two-colour generation in a chirped seeded Free-Electron Laser
B. Mahieu, E. Allaria, D. Castronovo +17
We present the experimental demonstration of a method for generating two spectrally and temporally separated pulses by an externally seeded, single-pass free-electron laser operati…
Chirped seeded free-electron lasers: self-standing light sources for two-colour pump-probe experiments
Giovanni De Ninno, Enrico Allaria, Benoit Mahieu
We demonstrate the possibility to run a single-pass free-electron laser in a new dynamical regime, which can be exploited to perform two-colour pump-probe experiments in the VUV/X-…
