Application for Liquid Helium Supply

If your division is not ISSP, you must contact your Institute and pre- approved.
If you have any questions and ask for more details, please contact us.

Also, for the user is not ISSP division procedure of registration would be different as listed below. Please contact and ask for the details to the member of the use of cryogen committee. (Graduate School of Frontier Science Professor Nohara or Professor Mizokawa)

Procedure

The necessary procedure is showing as a picture below. Registration is needed when newly use Liquid Helium. After registration is done, “ file an application for supply” “take out and return the vessel” will go on.

※1 In case of not sharing the vessel for some reasons we might adjust the date of supply.

※2 It used be the waiting time during supply was about one to two hours. Now with the new system, sharing the vessel with several users, we are able to reserve liquid helium ahead of the time. The waiting time is only for typing information in the computer. Please, leave a 10% of volume. And keep the vessel cold. If the vessel is at room temperature we have to ask you to pre- cool it.

※3 The volume of supply is automatically measured so when the weight of vessel changes, then data will not read correctly. Please don’t remodel the vessel(for example, the head part of sewage lock to rubber stopper) and return the vessel as same as when you check out the laboratory.

Specific Way of Registration

• Registration form is available on the down load page from our site. We also have a registration form at our office.

• Registration is available Monday through Friday (excluding holidays)

  9:00A.M.〜17:00P.M. Please fill out information and hand in our office in person.

• For the best result and administration system, please register at least 2days before the actual date of liquid helium usage.

• Setting up for the recycle gas meter and the check valve, please refer to set up manual.

• If you have any questions, please contact us at our office. (ext: 63515)

Case of Purchased the New Liquid Helium Vessel

• When you purchase the new vessel or transfer from other org., please register the helium vessel.

• When the inside of helium vessel is at room temperature, it takes at least
  1 week to be able to function. (It needs to vacuum the air out and pre-cool.) We recommend early registration for your convenience.

• There is no special registration forms for the LHe vessel ;please use LN₂ vessel registration forms.

• We are able to supply the helium vessel that matches with our laboratory’s transfer tube. When the time of purchase liquid helium vessel, please consult with us.

• If you have any question, please contact us. (ext.63515)

• We ask for share of using vessels. If you cannot share the vessel for certain reason, please inform us.

Remarks and Other Notes

• We have limitation for the number of vessels. When you finish using vessel, please return it to us as soon as possible.

• For the best result and efficient supply, please use large vessels.

• We try our best to supply the liquid helium for reasonable price to our users. We are also trying our best for higher recycling rate. We appreciate your cooperation and understanding.

• If you have any questions, please contact us at Cryogenic laboratory.

Duties About Using Liquid Helium

For the best result and produce higher recycling rate, we need your cooperation. Thank you for your under standing and cooperation. Please read the lists down below.

1. Apply for “liquid helium user registration” “ liquid helium device registration

2. Place the check valve and flow meter that has been recommended by our laboratories to all the recovery pipes.

3. The test device needs to be connected to recovery pipe and collect all the helium gas. Especially, some device makes natural evaporation and that goes to the atmosphere but it needs to be improved. Then collect all the natural evaporation of the helium gas. If you cannot collect the helium gas we cannot supply the liquid helium. Improvement on device for details, please take a look at here.

4. Please report stock volume of helium. The first Monday of the month is supposed to be inventory day. Please submit the report same day of inventory. If the Monday is not working day, it should be next day or following week of Monday.

5. When the time of take out and turn in the helium vessel, please follow the necessary steps. If you take out without notice you will be penalized.

6. When you return liquid helium vessel, please leave more than 10% of liquid helium volume. If you could not keep more than 10% of liquid helium volume, please contact and report to us. When you return without notice, we might ask to pre-cool the vessel and penalize.

7. All of the newly cryogen user must take a course that designated by cryogenic laboratory. There will be the class called “high pressured gas safety education” (course for the beginners). We will up date and inform you the details about the course on our web site.

FAQ

We gather the frequent asked questions. Please read and refer the Q & A.

Q1

We used most of the liquid helium by accident and that made volume of liquid helium lower than 10% of vessel volume.

A1

Please return the vessel as soon as possible to our laboratory. At same time please inform us. If you return the vessel without notice you might be penalized. If the vessel is warmer than nitrogen temperature, we might ask you to pre-cool and vacuum the air out at your laboratories. Please don’t judge yourself and always discuss with us.
