The development of various types of cryogenic target systems opens new opportunities for laser-matter interaction experiments. Existing systems of solid hydrogen targets, which are used with high-power laser systems for various experiments, including laser acceleration of protons, are considered. The details of target formation techniques are discussed. We also discussed some most challenging issues in target fabrication at low temperature and laser operation high repetition rate.
Key words: laser-plasma interaction, solid hydrogen target, proton beams, high repetition rate target.
