David Gregocki participates in experiment at Allegra Laser for Acceleration

EuPRAXIA-DN Fellow David Gregocki was invited to take part in experimental activities in ALFA, ELI-ERIC in Prague, Czech Republic.

ALFA (Allegra Laser For Acceleration) is the first laser plasma electron accelerator of its kind, powered by the high-repetition (1 kHz) L1-Allegra laser at the ELI-ERIC. It enables laser-matter interaction at relativistic intensity and delivers ultra-short (few fs) electron beams with tunable energy (up to 50 MeV) and frequency (up to 1 kHz)—the highest electron energy ever achieved by a kHz laser system.

In order to further characterize electron beams produced in the ALFA experiment, EuPRAXIA-DN Fellow David Gregocki was invited by Dr. Gabriele Grittani and his team to take part in alternative electron charge measurements using the integrated current transformer provided by his host institution, the Intense Laser Irradiation Laboratory, CNR-INO in Pisa.

Such collaborations strengthen relations between experimental groups and help to establish new connections between scientists around the world.
