A few days ago, the reporter learned from the Huairou Research Department of the Institute of Physics of the Chinese Academy of Sciences that the first batch of 5 experimental stations of the comprehensive extreme conditions experimental device have been open for appointments to users at home and abroad since January 20 this year. As of February 18, 11 scientific research institutes, colleges and universities, high-tech enterprises and other institutions from Beijing, Shanghai, Guangzhou, Jilin and other places have submitted applications for projects. The first round of applications will close on 28 February, after which the results of the application and the allocation of the experimental machine will be determined by expert review.

The comprehensive extreme conditions experimental device is one of the five large scientific devices built during the "13th Five-Year Plan" period of Huairou Science City, and it is also the first to enter the state of scientific research. The first five experimental stations to be opened for appointment are the extremely low temperature solid-state quantum computing (strong magnetic field) experimental station, the extremely low-temperature solid-state quantum computing (extremely weak field) experimental station, the low-temperature in situ scanning tunnel - angle-resolved photoelectron spectroscopy measurement experimental station, the micro-nano processing platform, and the process support platform. These experimental stations passed the performance process test in October 2021 and have the ability to run trial operation and open sharing.

"This year, the five experimental stations will open two rounds of applications for ordinary topics, with a validity period of 1 year, and the second round of applications is expected to start at the end of August." If global users need to use the comprehensive extreme conditions experimental device to carry out experiments, they need to apply for the subject first, submit an application by logging on to the major scientific and technological infrastructure sharing service platform of the Chinese Academy of Sciences, and after passing the review, they can submit the experimental application one or more times according to the time of the experimental machine applied. The relevant person in charge of the Institute of Physics of the Chinese Academy of Sciences introduced. In terms of costs, "in accordance with the management requirements of major scientific and technological infrastructure of the Chinese Academy of Sciences, major scientific and technological infrastructure mainly built with state investment should generally be open to users of public welfare institutions free of charge." Other users bear the corresponding costs and expenses in accordance with the agreement. The person in charge said.
The comprehensive extreme conditions experimental device is divided into four scientific experimental systems according to the research direction, including the physical property characterization system, the quantum state regulation system, the ultrafast condition material research system built in Huairou, Beijing, and the high temperature and high pressure large-volume material research system built in Jilin Province. These experimental systems are interrelated, supported and integrated, providing functional and internationally advanced experimental conditions for in-depth material scientific research under extreme conditions.
As an international advanced user experimental device integrating ultra-high pressure, extremely low temperature, strong magnetic field, ultrafast light field and other extreme conditions, the comprehensive extreme conditions experimental device will be used to expand the research space of material science, promote the discovery of new physical states, new phenomena and new laws, help research in many frontier fields related to material science, and strive to achieve world-class research results in the discovery of new high-temperature superconductors, breakthroughs in unconventional superconductivity mechanisms, breakthroughs in quantum regulation core technologies, and ultrafast regulation of physical properties.
It is understood that the five large scientific devices of Huairou Science City include the comprehensive extreme condition experimental device, the Earth system numerical simulation device, the high-energy synchrotron radiation light source, the multi-modal cross-scale biomedical imaging facilities and the "Meridian Project" Phase II. Among them, the comprehensive extreme conditions experimental device has officially started construction on September 30, 2017, and on October 30, 2020, some experimental stations have entered the scientific research state; the Earth system numerical simulation device has been inaugurated on June 23, 2021; at the end of October 2021, the construction and security project of high-energy synchrotron radiation light source has completed 80% of the total engineering volume; in 2022, scientific facilities such as high-energy synchrotron radiation light sources and multi-modal cross-scale biomedical imaging will be completed; at present, The second phase of the Meridian Project is in the full construction and implementation stage of the project, and the project is expected to be completed and accepted by the end of 2023.
