Description: We present bunch compressor designs for theInternationalLinear Collider (ILC) which achieve a reduction in RMS bunch length from6 mm to 0.3 mm via multiple stages of compression, with stages ofacceleration inserted between the stages of compression. The keyadvantage of multi-stage compression is that the maximum RMS energyspread is reduced to approximately 1 percent, compared to over 3 percentfor a single-stage design. Analytic and simulation studies of themulti-stage bunch compressors are presented, along with performancecomparisons to a single-stage system. Parameters for extending thesystems to a larger total compression factor are discussed.
