<p>PROBLEM TO BE SOLVED: To provide a device which can operate a refrigerant-free refrigerating machine with a continuously rotating system and can materialize extreme low temperature and can retain the extreme low temperature for a long time.SOLUTION: A device for materializing extreme low temperature with a continuous rotation system includes: a rotary table having a perforated hole on a rotation center part; a vacuum vessel fastened onto the rotary table; a refrigerant-free refrigerator having a cooling part on a vacuum vessel inner part; an inner cylinder which is fastened to a rotary table bottom part and includes a through-hole penetrating through in the vertical direction, an outward helium gas channel and a return helium gas channel which cause helium gas to pass therethrough and are opened to a side wall and an upper part; an outer cylinder which houses the inner cylinder rotatably in the inner part thereof and has outward and return helium gas connection ports connected to the helium gas channels; a compressor which causes helium gas to pass through outward and return helium gas channels and circulates helium gas through the refrigerant-free refrigerator; and a rotary joint for wiring which is fastened to the inner cylinder and conducts electricity rotatably. Therein, an internal wiring is caused to pass through the through-hole and a hole to supply electricity to an apparatus on the rotary table.</p> |
