2020 year-end inventory: endless innovation and new equipment come one after another

【Hot attention of Chemical Machinery and Equipment Network ] Instruments and equipment are tools for us to understand the world, especially at the moment, instruments are often the material leaders of production.
To put it simply, instruments and detection technology have become the mainstream link in promoting production, and the overall development level of instruments is also one of the important signs of the country's comprehensive national strength.

 

In recent years, due to my country's increasing emphasis on innovation, the field of scientific instruments has presented a new situation, with fruitful scientific and technological achievements.
Now that 2020 is over, let me take a look at what new products appeared in the instrument field in my country last year.

 

my country successfully developed an infrared skylight background measuring instrument
 

Astronomical research relies heavily on scientific and technological equipment.
As an important means of astronomical research, infrared observation has a high status in this field.
However, the development of infrared astronomy research in my country has been limited by the lack of good sites and detectors.
Domestic infrared detector technology has a relatively late start and relatively lagging development.
In addition, foreign infrared equipment has been used in China’s business Restrictions have made my country's infrared astronomy development seriously lagging behind.

 

With the continuous expansion of the field of astronomical research in my country in recent years, the desire of the Chinese astronomy community to have infrared astronomical observation capabilities has become more urgent.
my country also has a number of large-scale optical infrared astronomical observation equipment projects that have received support from the astronomical community.
After two years of research, the photoelectric detection technology team led by Wang Jian’s research group at the State Key Laboratory of Nuclear Detection and Nuclear Electronics, Department of Modern Physics, University of Science and Technology of China, based on the high response performance of the InSb detector in the 2.
5-5um band, Utilizing the linear variable characteristics of the linear variable filter in this waveband, a skylight background measuring device for continuous scanning and observation of infrared spectrum scanning in this waveband has been successfully developed.

 

Zhejiang* polymerase chain reaction analyzer calibration device passed the assessment
 

The polymerase chain reaction (PCR) analyzer is an analytical instrument used to amplify and amplify specific DNA fragments.
Its major feature is that it can greatly increase the trace amount of DNA.
In the fight against epidemics, the PCR analyzer is the core key equipment for virus detection.
Its working status and whether the detection results are accurate and reliable directly affect the efficiency and accuracy of virus detection.
Therefore, the calibration of the PCR analyzer is particularly important.

 

In 2020, the polymerase chain reaction (PCR) analyzer calibration device established by the Zhejiang Institute of Metrology has successfully passed the assessment of experts from the National Academy of Sciences and obtained a certificate of measurement standard assessment.
This standard device is a high-level measurement standard in Zhejiang Province, adding a new weapon to the province's epidemic prevention and control.

 

　　A new type of surface acoustic wave temperatureSensor device
 

　　The heat radiation loss caused by the high temperature environment will cause the sensor device to have a greater attenuation of sound waves, so the sensor working in this environment should have a sufficiently large quality factor and low loss.
Traditional wired active sensors cannot be used for temperature measurement in high temperature environments, and wireless passive temperature sensors based on surface acoustic waves provide a good solution for this.

 

　　*Doctoral student Li Xueling of the Ultrasonic Technology Center of the Institute of Acoustics and his supervisor Wang Wen, etc.
, used the short pulse method to extract the accurate reflection coefficient, and used a typical coupled mode model to optimize the design and simulation of the LGS/Pt structure surface acoustic wave temperature sensor.
And the test proves that the device has good high temperature sensing performance.
Studies have shown that surface acoustic wave high temperature sensing technology can be used for high-sensitivity temperature monitoring and early warning in high-temperature environments.

 

　　my country has developed an ultrafast scanning tunneling microscope
 

　　With the continuous development of microscopy technology, various fields are now closely related to microscopes, such as materials, education, medical treatment, biopharmaceuticals, agriculture, environmental protection, national defense technology, chemistry, physics, biology and other fields.
Microscopes all play a huge role.
In recent years, the original concept and core technology of ultrafast scanning tunneling microscopes have begun to innovate.
Many researchers have joined the fierce competition.
Jiang Ying's research group from the Quantum Materials Science Center of the School of Physics of Peking University also started ultrafast scanning tunneling microscopes in 2012.
Research.

 

　　In 2020, Professor Ying Jiang from the Quantum Materials Science Center of the School of Physics of Peking University, in cooperation with the * Research Institute of Physics Researcher Meng Sheng, Weng Yuxiang Researcher, and * Academician Wang Enge, successfully developed an ultrafast scanning tunneling microscope.
Using this device, the researchers conducted in-depth studies on the non-equilibrium dynamics of a single polaron.

 

　　The helium refrigerator developed by the Institute of Plasma Physics, Hefei Research Institute, Chinese Academy of Sciences passed the acceptance
 

　　From December 18 to 19, 2020, the Hefei* light source pre-research project 250W@4.
5K helium refrigerator independently developed by the Institute of Plasma Physics, Hefei Research Institute, Chinese Academy of Sciences completed the project contract acceptance and on-site at the National Synchrotron Radiation Laboratory of the University of Science and Technology of China Process testing.

 

　　The 250W@4.
5K helium refrigerator completed the factory test in July 2020.
The acceptance expert group listened to the project team's acceptance report, on-site process test outline and process test report in detail, and inspected the equipment operation and test results on the spot.
The test results show that the cooling capacity reaches 270W, and the liquefaction rate is 104L/h, which is higher than the design requirements.
The helium refrigerator is about to be put into use, and will provide low-temperature test conditions for the research of Hefei* light source storage ring superconducting high-frequency technology after it is put into operation.

 

　　Instrumentation is the "multiplier" of the national economy, and the role of the "material judge" in enterprise technical supervision in the implementation of laws and regulations such as product quality assessment and measurement.
For production and life, the application of instrumentation is a product that has competitiveness and enters the market economy.
The only way.
In addition, scientific instruments are still only the premise of innovation and technological innovation, one of the main content of innovation research and one of the important manifestations of innovation achievements.
In short, to promote the development of instrumentation is of great significance to our country's life, production, economy, technology and other aspects.
