[ Focus on Chemical Machinery Equipment Network ] Recently, the non-liquid helium dilution refrigerator independently developed by the Institute of Physics of the Chinese Academy of Sciences achieved extremely low temperatures below 10mK, marking a breakthrough in the development of extremely low temperature instruments in China
.
Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment.
Dilution refrigerator "small encyclopedia"
Dilution refrigerator "small encyclopedia"The dilution refrigerator is a scientific research instrument that can provide an environment close to absolute zero
.
It has been widely used in scientific research fields such as condensed matter physics, material science, particle physics and even astronomical exploration .
The non-liquid helium dilution refrigerator is different from the traditional wet dilution refrigerator that relies on liquid helium for auxiliary cooling.
It does not require liquid helium supply, has a large sample space, has a long continuous operation time and is convenient for operation and maintenance.
It has rapidly become popular in the past decade and has become the mainstream of the market.

Quantum computing is currently the main battlefield of science and technology competition among countries in the world.
The dilution refrigerator provides the necessary extremely low temperature environment for the normal operation of quantum computers, and is an irreplaceable key device in quantum computing research
.
At present, China's such instruments are totally dependent on imports, which is the core technology of "stuck neck" that needs to be broken
.
Therefore, it is urgent to develop a domestically produced non-liquid helium dilution refrigerator

At present, the domestic companies engaged in the research of ultra-low temperature refrigerators mainly include China Shipbuilding Heavy Industry Pengli Ultra-low Temperature Technology Co.
, Ltd.
and Anhui Wanrui Refrigeration Technology Co.
, Ltd.
The low-temperature refrigerators of these two companies are concentrated in traditional small dilution refrigerators, and large-scale dilution refrigerators.
The domestic market in the field of machinery still needs to be imported

.
The non-liquid helium dilution refrigerator can quickly change samples and cool down to low temperatures, and can install various complex DC and RF experimental leads
.
The modular design of the sample loading system of the system is preferred by downstream customers, which brings full freedom to customers to customize and modify the system
.
As China's investment in superconducting quantum computing increases, it is estimated that the domestic annual demand for dilution refrigerators will be around 40-60 units in 2024, and the market size of large-scale dilution refrigerators will reach 264 million yuan

The road to research and development of scientific research instruments in my country is getting wider and wider
The road to research and development of scientific research instruments in my country is getting wider and wider Mastering the core technology of dilution refrigeration indicates that China has the ability to provide guarantees for extremely low temperature conditions for cutting-edge research such as quantum computing
.
The rapid development of China's economic strength in recent years has driven the continuous improvement of scientific and technological strength
.
The improvement of the country's scientific and technological strength is the result of the diligent research input of scientific researchers and the result of the upgrade and transformation of core instrument components
.
The level of domestic science and technology has been significantly improved, and at the same time it has led to the rise of many domestic brands with core technical capabilities
.
At this stage, China's scientific and technological strength has gradually caught up to the level of developed countries.
Behind the hard strength of science and technology is the strength of China's independent innovation

2021 is a critical year for the development of China's scientific and technological undertakings and a crucial year for reaching the world stage
.
The level of independent research and development of scientific research instruments is an important indicator of independent innovation capabilities.
Many major scientific discoveries are made by scientists in the process of improving instrument performance or developing new principle instruments
.
To make up for shortcomings in this area as soon as possible, in addition to focusing on research and development, we must also focus on promotion and use
.
The development of scientific research instruments is often the shortcoming of our country, and there is still a certain gap between the level of research and development and production compared with the international level
.
Only with continuous exploration and continuous research and development, with such persistence and hard work, various scientific research instruments can finally be successfully developed

At present, domestic scientific research instruments still face some difficulties in the actual promotion and application, and it is often difficult to gain the trust of users
.
Compared with the mature foreign instruments that have been used for many years, the newly developed domestic instruments may have some shortcomings, but if they are not used more, they will not get feedback and will not be able to continue to improve and perfect them
.
In fact, the advanced scientific research instruments in the world have been continuously matured and improved from generation to generation in years of application
