The X-band linac of the Next Linear Collider (NLC) will accelerate bunches of about 100 {mu}m rms length to energies of 250{endash}750 GeV. The task of the NLC bunch compressor is to reduce the initial bunch length of 4{endash}5 mm, at extraction from the damping ring, by a factor of 40, to the desired value. This task is accomplished in two separate stages. The first stage at 2 GeV consists of an rf section and a wiggler. The second stage at 10 GeV is formed by an arc, an rf section, and a chicane. The system is designed such that the final bunch phase is insensitive to initial phase errors and to beam-loading in the intermediate S-band pre-linac. Additional decelerating rf sections are employed to compensate significant longitudinal aberrations. {copyright} {ital 1996 American Institute of Physics.}
