Sammanfattning

A travelling-wave thermoacoustic refrigerator design, suitable for CERN's new Ionization Profile Monitor, was devised based on numerical calculations. The design features a He-filled looped tube containing an acoustic wave produced by an acoustic driver. The parameters of the cooling structure, the regenerator, were constant, whereas the cooling power as a function of tube radius and mean pressure of the gas were investigated. The target, a maximum cold temperature of 273 K and a minimum cooling power of 12 W, were reached with tube radius 15 mm at either cold temperature 270 K and mean pressure 7 atm, or at cold temperature 260 K and mean pressure 8 atm. The coefficient of performance was also determined.
