Proposal System and Fees

»Use of Liquid He

Users (project leaders) are required to pay for the lequid He actually used for their experiments. For the use of lequid He, please contact the Beamline Scientist in advance.

1. In the case of liquid He provided by JASRI

After the experiment, a billing statement is issued by JASRI based on the amount used and sent to the billing organization. Please make sure that the payment is made within 60 days of the invoice date. The unit price of liquid He is 2,794 yen/liter. Please note that the price is subject to change. For instructions on how to measure the amount of liquid He, please click here.

2. In the case of liquid He prepared by project leaders

Project leaders are responsible for bringing He gas to and from SPring-8 whether they use a vendor or not. Please make sure that the mouth of your liquid He container fits the transfer tube in advance.

Note: Due to facility restrictions, you cannot make a choice between 1 and 2. Please check the following list and consult with the Beamline Scientist in advance.

  • Beamlines where you can make a choice between 1 and 2:

BL02B2, BL08W, BL09XU, BL25SU, BL28B2, BL43IR

  • Beamlines where liquid He is provided by JASRI:

BL39XU, BL47XU

  • Beamlines where project leaders need to prepare liquid He:

BL02B1, BL27SU

3. How to measure the amount of liquid He

To measure the amount of liquid He provided by JASRI used, the Liquid Cryogen Level Monitor (CRYOMAGNETICS, Inc./LM-500) is used. Please follow the directions below:

1. Start of experiment: The amount remaining in the container is displayed on the level monitor. Enter the value (in 0.1 cm increments) in the Liquid He Consumption Form as a start value. (Some beamlines use different increments.)

2. End of experiment: The amount remaining in the container is displayed on the level monitor. Enter the value (in 0.1 cm increments) in the Liquid He Consumption Form as an end value. (Some beamlines use different increments.)

3. After experiment: Subtract the end value from the start value to find the amount of liquid He used (in 0.1 cm increments) and enter in the Liquid He Consumption Form. To convert from cms (liquid level) to liters (volume), linear interpolation is used based on the conversion table attached to the container.

4. Before leaving SPring-8: Report the total amount of liquid He used by filling out a Beamtime Report online. Please make sure that the entered amount is correct before clicking “Save”; based on this report, the resulting user fee is automatically calculated.*

*Rounded to the nearest whole number (in yen).

Note: There are beamlines that use a different model; please check with the Beamline Scientist. (The information on the model may be available later.)

4.For billing of Liquid He

In accordance with the User Fee System, when you use the liquid He provided by JASRI, please enter the amount used in the Beamtime Report and submit online. JASRI claims the expenses based on the amount listed in the Bematime Report.

Beamlines where liquid He is available:

BL02B2, BL08W, BL09XU, BL25SU, BL28B2, BL39XU, BL43IR, BL47XU
