Here will be another major scientific facility! How will the world's first "zero magnetic" space expand the boundaries of humankind?

Large scientific facilities are called "the country's heavy weapons" and are the core echelon of the construction of the country's strategic scientific and technological forces. They are related to the seizure of global scientific and technological commanding heights and high-quality economic and social development.

At present, Zhejiang has built two large scientific facilities, both located in Hangzhou.

The report of the 8th Plenary Session of the 13th Hangzhou Municipal Party Committee clearly stated that by 2025, the high-level scientific and technological innovation platform matrix will be expanded and upgraded, the third major scientific facility will be planned, and the number of national key laboratories will exceed 20 throughout the year.

Recently, two large scientific facilities in Hangzhou have made new progress.

The "giant" carries two large hanging baskets and spins rapidly

Take you to achieve "one step a thousand miles"

How to achieve “one step, a thousand miles” in the laboratory?

The ultra-gravity centrifuge simulation and experimental device can construct an experimental environment for the movement of multi-phase media from instantaneous to ten-thousand-year time scales, from atomic level to kilometer-level spatial scales, and from normal temperature and pressure to high temperature and high pressure.

With it, researchers can simulate the time and space compression of "a glance for a thousand years" or "a step for a thousand miles" in the laboratory.

This large device is hidden in the "Hangzhou Supergravity Field".

The Hangzhou Supergravity Field is located in Yuncheng, Yuhang District, covering an area of ​​89 acres and a total construction area of ​​approximately 34,560 square meters. It will be built with 18 airborne devices including three centrifuge hosts (including verification machines), six experimental cabins, as well as supporting facilities such as experimental buildings, 110 kV substations, data centers, smart experimental parks, and temperature control subsystems.

Recently, the Hangzhou supergravity field project reached a milestone - the supergravity experiment building was officially put into use.

The ultra-gravity experiment building is in the shape of a Chinese character "丰". The core in the middle is the main engine hall, which is used to house three ultra-gravity centrifuges, including the model preparation machine, heavy-load machine, and high-speed machine.

The east and west auxiliary halls are located on both sides of the main hall and are used to place auxiliary equipment for six experimental cabins, including slope and high dam, geotechnical earthquake engineering, deep sea engineering, deep earth engineering and environment, geological process and material preparation.

The northern part is the precision testing area, which is used to place various precision experimental instruments such as electron microscopes.

The southern part is the research and exchange area, which has an entrance lobby, communication space, multi-function hall, etc.

At present, the model preparation machine and verification machine of the Hangzhou Supergravity Field have been installed, and are expected to pass acceptance and enter trial operation in early 2025.

The other two centrifuges - a heavy-load centrifuge and a high-speed centrifuge - are also being processed and manufactured, and are scheduled to be transported to the site for installation in April 2025.

When the centrifuge is "working", it is like a giant using his two arms to carry two large baskets and spin them rapidly. The supergravity field generated by the rotation will produce a time and space compression effect on the objects in the baskets.

Through this device, researchers can simulate changes in mountain and landforms in a very short time.

If a soil contaminant migration experimental device is installed on an ultragravity centrifuge, the large-scale and long-duration migration of pollutants underground can be seen.

When the Hangzhou supergravity field project is fully completed, it will become the world's largest and most powerful multidisciplinary supergravity experimental facility, providing an advanced experimental platform for the implementation of major national scientific and technological tasks, the research and development and verification of new technologies for major projects, and the development of cutting-edge material science.

The brain's magnetic field is only one billionth of the Earth's magnetic field

Can it be measured?

Everything on Earth has a magnetic field, but the strength of the magnetic signal varies.

The magnetic field of human organs contains important information about life and health. However, the human magnetic field is extremely weak. The magnetic field of the heart is one hundred millionth of the earth's magnetic field, and the magnetic field of the brain is only one billionth of the earth's magnetic field, making it difficult to measure.

Professionally, magnetic fields that are difficult to measure, such as the human body's magnetic field, are called "extremely weak magnetic fields."

Today, Chinese scientists have made a new breakthrough in this field. A medical device that can detect the extremely weak magnetic field of the human body has been developed. This medical device that can measure heart and brain magnetism is closely related to the construction of a large scientific facility in Hangzhou.

On the south bank of the Qiantang River, the extremely weak magnetic field facility located in Jiangnan Science City in Binjiang District has the unique skill of "precisely measuring extremely weak magnetic fields".

Not long ago, the construction of the west wing of the extremely weak magnetic facility started, covering an area of ​​47,000 square meters. Three cross-research platforms will be built: a large-scale magnetic shielding space technology cross-research platform, an ultra-high sensitivity extremely weak magnetic field and inertial measurement device and instrument cross-research platform, and a chip-based quantum sensor process technology cross-research platform (part).

After completion, the three cross-research platforms will promote the incubation of emerging industries through the transformation of scientific and technological achievements, provide a key platform for the research and development, testing and technical verification of extremely weak magnetic facilities, and meet the needs of upstream research and development results and downstream results transformation.

News has come from the Planning and Construction Command of Zero Magnetic Valley and Science City that the construction of the extremely weak magnetic field facility is about to usher in the "first shovel", and it will become the world's only "zero magnetic" space with the highest performance and largest space.

By accurately measuring extremely weak magnetic fields, people can obtain new experimental data, reveal new natural phenomena, discover new scientific laws, and gain new tools to understand the world.

After the extremely weak magnetic facility is completed, it will provide an extreme weak magnetic environment and extreme measurement methods for deep space exploration, aerospace, life and health and other fields, enabling my country to maintain its leading edge in this technological field.
