Precise control of high-frequency ultrasounds in thin crystals for the development of tunable narrowband and directional gamma-ray sources
Emmanouil Kaniolakis-Kaloudis, Nektarios Papadogiannis, Yannis Orphanos +2
This work presents a complete methodology for the precise characterization of the acoustic field inside crystal-based devices driven by high-frequency ultrasounds towards the gener…
Efficient ultrafast photoacoustic transduction on Tantalum thin films
Konstantinos Kaleris, Emmanouel Kaniolakis-Kaloudis, Evaggelos Kaselouris +8
Nano-acoustic strain generation in thin metallic films via ultrafast laser excitation is widely used in material science, imaging and medical applications. Recently, it was shown t…
Narrowband gamma-ray radiation generation by acoustically driven crystalline undulators
Konstantinos Kaleris, Evaggelos Kaselouris, Vasilios Dimitriou +7
In this paper we present a novel scheme for the controlled generation of of tunable narrowband gamma-ray radiation by ultra-relativistic positron beams inside acoustically driven p…
