On the basis of a conventional 4 K Gifford-McMahon (GM) cryocooler, they developed a new 2 K GM crycooler, which can provide considerable cooling capacity and yet being highly compact in physical size. A series of experiments were conducted to confirm and show the cooling characteristic and cooling capability of this new cryocooler. Under no-load condition, the lowest temperature reached about 2.41 K on the second stage and the temperature oscillation displacement was less than ±20 mK. Even under a thermal-load of 1 W / 20 mW, temperature reached 45 K on the first stage Regenerator and 2.41 K on the second stage Regenerator. The temperature contours and pressure contours of the Regenerator were calculated and plotted using CFD. The materials for the study were decided to be Phosphorous bronze for its better conducting properties and fluid taken was helium.
