Abstract

There is disclosed a cold head (2) for a pulse tube cooler, comprising: a regenerator (4) having a first end (6) connectable to a compressor; a pulse tube (14) having a first end (12) and a second end (16); a heat exchanger (10) connected between a second end of the regenerator and the first end of the pulse tube; and a phase control device (26) connected at the second end of the pulse tube for controlling the flow dynamics in the pulse tube to provide cooling at the heat exchanger, thereby maintaining a negative temperature gradient between the first and second ends of the regenerator, wherein: the pulse tube comprises a wall (15) having a porous portion (28) for allowing a working gas to enter or leave the pulse tube directly through the porous portion, the porous portion extends substantially parallel to the axis of the pulse tube.
