Abstract. The experimental goal of MuSUN experiment at Paul Scherrer Institute (PSI) is a high-precision measurement of the rate for μ-meson capture by deuteron to better than 1,5 %. Experimental technique based on Cryogenic Time Projection Chamber (CryoTPC) specially developed at St. Petersburg Nuclear Physics Institute is applied. The chamber is filled with deuterium of ultra-high isotopic and chemical purity. The detector is cooled by closed neon circulation system. Basic operation principles of the CryoTPC and its cooling system are described.
