Synergetic Extreme Condition User Facility (SECUF) is a large research infrastructure built by the Institute of Physics, Chinese Academy of Sciences and co-constructed by Jilin University. SECUF is designed to provide international top-class extreme experimental conditions such as extremely low temperature, strong magnetic field, ultra-high pressure, and ultra-fast light field for domestic and foreign users to conduct frontier research in material science such as material synthesis, physical characterization, quantum regulation, and ultra-fast processes. SECUF has been fully transferred to trial operation and opened for use by domestic and foreign users in early 2023. The first round of general proposal application for the year 2025 will be open to users on March 1st, 2025.

General Proposal Application Method

To carry out experiments using SECUF, users need to log in to the Chinese Academy of Sciences Large Research Infrastructures User Service Platform (https://lssf.cas.cn/en/index.jsp), fill in the application for the general proposal. After the review of proposal is approved, specific experimental time can be reserved one or more times according to the approved experimental time (valid for one year).

Proposal Application Time

SECUF opens two rounds of general proposal applications per year to users. The first round of applications runs from March 1 - March 31 each year, and the second round runs from September 1 - September 30 each year. The first round of general proposal application for the year 2025 will be open to users from March 1 - March 31, 2025.

A total of 20 experimental stations will be open in this round of general proposal application.

A1 Ultra-low temperature high pressure physical property measurements - diamond anvil cell station

A2 Ultra-low temperature high pressure physical property measurements - cubic anvil cell station

A3 Ultra-low temperature high magnetic field quantum oscillation experimental station(Only 18T for applications)

Instructions for User Proposal Application

The process of applying for the use of SECUF is specifically divided into three parts: proposal application, experimental reservation and feedback of user results.

1.Proposal application: user submits application - pre-approval by user office - preliminary review by equipment administrator - correspondence evaluation by experts - meeting evaluation by User Committee - final review by the head of experimental station - notify the user - user gets the experimental time;

*Please stamp the official seal of the institution on the first page of the project application and upload the electronic version at the “Science Overview- Science Case”.

2.Experiment reservation: user submits application for experiment - equipment administrator reviews and allocates experimental time - user confirms experiment;

3.Feedback on user results: user submits research results (papers, patents, awards, etc.).
