Proposal System and Fees

»Use of Helium Gas

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

1. In the case of He gas provided by JASRI

At beamlines listed below where He gas experiments are often conducted, He gas and the He gas mass flow measurement system are available*. 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 He gas varies depending on the type of He gas as indicated below. For instructions on how to measure the amount of He gas used, see the section below.

*The fee for He gas used for shared instruments such as Be window or He path is included in the fixed fee.

**Multiply the unit price by the value displayed on the mass flow meter (liter) and round the result down to the nearest 10 yen to find the amount to be charged.

2. In the case of He gas 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 check with the Beamline Scientist if your gas cylinder/container fits the connecting port of the mass flow meter in advance.

3.How to measure the amount of He gas

To measure the amount of He gas remaining at the end of experiment (by the liter), use the mass flow meters, which are installed in beamlines where He gas is available.

Instructions for project leaders:

1. Start of experiment: Press the yellow Start button, and the counter is reset to zero. Then the meter starts to measure the flow of the gas by the liter.

2. End of experiment: Register the value displayed on the meter. Before leaving SPring-8, Enter the value in the online Beamtime Report.

4.For billing of He Gas

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

Beamlines where He gas is available:

BL02B1, BL02B2, BL04B2, BL09XU, BL13XU, BL19B2, BL25SU, BL39XU, BL41XU
