Abstract

The work covers a series of laser wakefield acceleration (LWFA) experiments carried out at the petawatt laser PEARL (PEtawatt pARametric Laser, Nizhny Novgorod, Russia). The use of different focusing angles and gas jets of various sizes is discussed. Modulation of the gas jet concentration profile for electron trapping improvement has been studied in experiments. Specific singe-shot laser-plasma interaction diagnostics adapted for low repetition rate systems with low output parameter stability, as well as a two-screen magnetic spectrometer with advanced accuracy of spectral measurements of electron bunches are considered.
