Description

The KAIO-Beamline was designed to address scientific applications of laser-plasma accelerators such as complex parametric studies in radiobiology [1]. Its modular design incorporates (i) a commercial ultrafast laser driver, (ii) a temporal post-compression stage based on multi-pass cell technology [2] to reach optimal electron acceleration conditions in the few-cycle regime [3], and (iii) a compact plug & play electron accelerator module.
Here we will present the first implementation of KAIO-Beamline [4], using an ASTRELLA USP Ti:Sapphire laser driver (Coherent Inc.), delivering 7 mJ 40 fs pulses at 1 kHz repetition rate. The laser pulses are comprehensively characterized with the novel spatio-temporal metrology techniques INSIGHT [5] and TIPTOE [6].
