Cryogenics Division


Outline

Cryogenic Division, one of the four divisions of Research Facility Center for Science and Technology, is entrusted with a mission to make a support of cryogenic research in the University of Tsukuba. Specifically, there are two missions of supplying cryogen of liquid nitrogen and helium, and of offering cryogenic research equipment for joint usage in the university. Also, the cryogenic department is conducting various studies such as phase transformation of iron-based alloys in strong magnetic field, cryogenic application of shape memory alloys, and critical phenomena of Helium3 in sub mK range.

Mission

Specific missions of Cryogenic Division are the following:
1. Supply of cryogen
Cryogenic Division supplies liquid nitrogen and helium to many users in the university. The consumption of cryogen in the university increases every year and is used not only in the fields of physics, chemistry or engineering, but also in wider fields such as medicine, agriculture and forestry, biology and physical science. The recycling system is installed for the supply of liquid helium; evaporated helium gas after the usage of liquid helium is recovered and recondensed for the next supply. This recycling system contributes much to low cost and stable supply even in the period of short supply of helium in the world.

2. Joint usage of cryogenic research equipment
Cryogenic Division is equipped with several cryogenic experimental facilities which are offered for joint usage in the university. There are equipment for low-temperature measurements of electrical and magnetic properties of soild, a scanning electron microscope, etc.

3. Safety training for using liquid nitrogen and liquid helium
Cryogenic Division privides home made educational vieos for those who begin using cryogen.

4. Other services
Cryogenic Division carries out legal inspection of closed-type liquid nitrogen containers in the university.

Facilities

The building of Cryogenics Division consists of two blocks. One is Liquefaction building and another is Experimental building. The former incorporates a helium liquefier and associated machines, and liquid nitrogen tanks. The research equipment are located in the latter. Some of them are enlisted in the Open Facility.
