The NC linacs are discussed in this article. Such linacs can differ each other significantly by mode of operation (pulsed or continuous), mass to charge ratio (1 - A/Z - 6.5), current magnitude (from 0.1 mA to 50 mA), etc. Anyway the layouts of these linacs have much in common. Different layouts of NC linacs are considered and the dynamics of particles in them for various projects is described. The requirements for the construction of NC linacs are substantiated, as well as the choice of the main parameters of the accelerating sections: operating frequency, maximum field strength, channel acceptance, focusing period structure, transition energy between accelerating sections, synchronous phase values, etc. The main design parameters of accelerating structures and their electrodynamic characteristics are given. The problems of technical realization for such linacs are discussed. PB - JACoW Publishing CP - Geneva, Switzerland ER -
