Introduction of Liquefier Room

We mainly do the service as listed above on this page. Especially, supplying liquid helium is over 170,000 litters per year. The supplying amount is first or second place, among the all the similar research facilities in the domestic. On the rise of demand liquid helium, to correspond the users. The opportunity to relocate to the Kashiwa campus then the liquefy equipment and facility were renewed and built.

Major changes

• Liquefier ：recovery rate150L/h→200L/h

• Ability of preservation：3960Nm³→4500Nm³

• Compressor for recovery purpose：90Nm³→180Nm³

• Automation managing gas system.

• Automation LN2・LHe flow calculation.

April 2000,other equipment had been relocated from Roppongi campus to Kashiwa campus. Then liquefy recovery system has build completely. Now the liquefy room trying to cover the entire Kashiwa campus' liquid helium . For that purpose we change modify the equipment occasionally.

Details about the equipment is down below or take a look at the .brochure

About an identification of freezing mixture use class completion of a course

About a freezing mixture use class

We offer the class for all the liquefier room user at every spring. Subject for(※1)「High pressured gas newcomer's session」After completed the course ,we issue the ID card.(Picture on the left)

If you have not taken this class, you are not able to use freezing mixture supplied from our lab.

※1 The newcomer of the Kashiwa campus have to take this course; even though the person took class from other institute or had the experience of using freezing mixture.( First time ISSP Liquefy room user)A class becomes an exemption partly,if you have a certificate of Koatsu Gas Kogyo production preservation person in charge. If so please contact us at (ekika@issp.u-tokyo.ac.jp Ext.：63515)

Details about the class please look at Here.

We would update about the holding date and time of a class in a home page. In addition, please contact one entered in the year middle because we teach it individually.(ekika@issp.u-tokyo.ac.jp Ext：63515)

If an identification of freezing mixture use class completion of a course became needless

If an identification card become needless as graduate from school,change of job,retirement and so forth, please return to the following address. Simply, return in person at the cryogenic lab. is acceptable.
