Sample Environments
List of sample environment instruments (SE) is shown below.
Please check the specification when applying the proposal as well as registering the experiment.
Please contact technical staff members if you have any questions.
Consumables
Consumables such as sample containers are basically to be prepared by users. Please contact the instrument leader in advance.
Liquid nitrogen is to be provided by our facility.
The cost of liquid helium is to be borne by users. Please contact the instrument leader or technical staff members for details.
