Many of the subsystem components of this large-scale laboratory have not been manufactured in China before, but the machine tool research institute and instrument equipment company under Huaxing Group are also responsible for the manufacture of many key components, including world-class vacuum inserts, 6 sets of large-size high-precision mirror bending mechanisms, stainless steel ultra-high vacuum chambers, vacuum chamber oscillators, variable angle plane grating monochromators, etc., showing the amazing machining technology of Huaxing Group. →+?8→.?

Of course, not all components need to be produced domestically, and some mature components are also purchased from foreign instrument and equipment manufacturers.

In fact, since 93 years of the last century, Professor Wolfson wrote a report to the government to explain the necessity and importance of building a third-generation synchrotron radiation light source, and this project was also launched at that time, and the project was codenamed "diamond".

However, there has been a heated debate about whether the project should be built in Daasbury, Cheshire, or Didcote, where the sRs are located, or Didcott, South Oxfordshire.

At that time, the Gallic chickens were also interested in co-building the project, and it was not until 2000 that the decision was made to build the Soleil light source independently on the outskirts of Paris, and John Bull finally decided to locate the diamond light source facility in Didecott.

Although these two light source facilities are determined, but the speed of construction is really slow, Huaxing Group company to build this light source facilities is 02 years in the second half of the start of construction, it took 38 months after the first phase of the project has been completed, the two light source facilities are still under construction.

This large-scale laboratory is now operated and managed by Shenguang Light Source Joint Venture Co., Ltd., Huaxing Group is the major shareholder, and the Chinese Academy of Sciences and the enterprises directly under Yanjing City are also respectively shareholdings. ▲≥ Eight ▲ ≥ Eight ▲ ≥ Read ▲ ≥ Book, .√.≧o

At present, 7 line stations have been built in the laboratory, including extreme conditions line station, materials and magnetodynamics line station, 3 molecular crystallography line stations, nanoscience line stations, etc., two of which are dedicated to life science and pharmaceutical research.

Now the technical team of Huaxing Group has begun to use these line stations to carry out actual experiments to carry out technical verification tests on this set of light source facilities.

This process also requires time to be dressed up, and by the time the validation tests are completed, the large laboratory can be officially operational.

Although the first synchrotron radiation light was successfully obtained just a few days ago, various tests are now needed to test whether the facility can operate stably for a long time.

Huaxing Group Company is naturally the first to get close to the water, and many experimental projects are now directly started.

The second phase of the construction budget of this laboratory has been determined last year, and Shenguang Light Source Co., Ltd. will invest more than 2 billion yuan to build a total of 60 line stations, the construction time is five years, and at least 10 line stations will be built every year.

Originally designed to operate for 5,000 hours per year, the large lab is expected to run for 30 years or more, with more than 3,000 customers per year.

In fact, when the first phase of the construction of this large-scale laboratory was not completed, there were many scientific research institutions in China to come to the door to submit applications, all hoping to be the first to use this large-scale laboratory for experiments, and many experts and professors are looking forward to the official opening of this light source facility every day.

Yang Jie knows that the central government is now paying more and more attention to R&D investment, and many domestic companies have an increasing demand for large-scale experimental facilities for the third-generation synchrotron radiation light source.

He is not worried about the situation that this light source facility can not find customers after it is put into use, with the attention of domestic companies and enterprises to research and development, this facility will only be in short supply in the future, and may not be able to meet the needs of domestic research and development.

Yang Jie then inspected the beamline station, which is mainly composed of four main parts, including the front part that leads the beam from the exit of the storage ring, and there is a shed in the middle, where a certain wavelength of light is selected and focused, and in order to achieve these purposes, it is also equipped with various optical components such as monochromators, mirrors, slits, filters and lens groups.

Most of these optical devices are developed by the three sunshine science company under Huaxing Group Company, because these beams are extreme ultraviolet light, the energy of light, The destructive is extremely high, and the wavelength of extreme ultraviolet light is at least 10 nanometers, this light is easily absorbed by the material including the lens glass, so it is necessary to use a reflector instead of transparency, and the reflectivity of the ordinary polished mirror is not high enough, and the double mirror design of the Bragg reflector must be used, which can concentrate the reflection of multiple layers into a single reflection, and must develop a coating that will not absorb the extreme ultraviolet light source.

Not only that, but the mirrors produced must be unprecedentedly flawless, and the size of the defects can only be measured in picometers!

For this Three Sunshine Science Company, it really made a lot of money, and it took a lot of ways to do it in the first half of this year.

Because the gas also absorbs deep ultraviolet light and affects the refractive index, a highly vacuum system must be used in the line cavity of the line station.

All the parts and materials of this set of light source facilities challenge the limits of human technology, Huaxing Group and many scientific research institutions have taken out all the technologies, and finally manufactured these extremely sophisticated and complex instruments and equipment.

In the online station laboratory, Yang Jie also noticed that the laboratory was equipped with various experimental instruments such as remote regulators and detectors for observing samples.

The detector is an ultraviolet light camera jointly developed by Huaxing Group and Aerospace Group Corporation, and the devices in the camera use an ultraviolet light sensor successfully developed with gallium nitride materials, and this set of cameras is used on the Fengyun series satellites.

Because the photoelectric sensor made of gallium nitride material is very sensitive to ultraviolet light, it can be said that the resolution of this camera is the highest in the current stage.

The synchrotron radiation technology of the light source of Shenguang Light Source Co., Ltd. is mainly divided into three categories, namely diffraction, spectroscopy and imaging, and different beamline station laboratories can carry out different types of experiments with different experimental performance.

The light is directed through the beamline to the various experimental stations and provided to the experimenter. Scientists from multiple disciplines can conduct research ranging from finding new substances and medicines to solving a wide range of environmental problems.

At the beginning of the design, the design team took into account the different needs of customers, and the laboratory was also equipped with large-scale diffractometers, dual crystal monochromators and other instruments and equipment, and customers only needed to bring samples to conduct experiments. 11
