[ China Instrument Network Instrument R&D ] On August 16, the signing ceremony of the cooperation framework agreement for “Dalian Advanced Light Source Pre-Research†project, one of the 2018 municipal key pre-projects in Dalian, Liaoning Province, was held at Dalian Institute of Chemical Physics, which marked “Dalian The Advanced Light Source Pre-Research project entered the official launch phase.
Free-electron laser is the most advanced new-generation light source in the world today, especially the high-gain free-electron laser that has developed rapidly in recent years. It has excellent characteristics such as high brightness, ultra-short pulse and full coherence. It is the world's major developed countries competing to develop. And new areas of preemption. The free electron laser device can accurately capture the dynamic images of molecules, atoms and other microscopic particles in chemical reactions, and can be used to "film" molecules and atoms. Therefore, for energy, chemistry, physics, biology, medicine, materials, etc. The field of basic science has an indispensable revolutionary impetus.
"Dalian Advanced Light Source" is called "High Repetition Frequency Soft X-ray Free Electron Laser Device" and belongs to the national major science and technology infrastructure. “Dalian Advanced Light Source†is a high-repetition frequency free electron laser device with a repetition rate of one million Hz, which means that scientists can obtain more microscopic particle image information in a shorter time and greatly improve the efficiency of scientific research. Upon completion, Dalian will have a world-class, large-scale scientific installation that will attract elite scientists from around the world to conduct research activities.
The pre-research project signed this time is the pre-production research project of “Dalian Advanced Light Sourceâ€. The main purpose is to break through and solve the key core technical problems of “Dalian Advanced Light Source†and pre-develop instruments and equipment that have a significant impact on project quality and progress. To achieve the goal of reducing the overall project construction risk and ensuring the smooth development of the project.
In addition, this is another high-repetition frequency free electron laser advanced light source that has been launched in China after the construction of the Shanghai hard X-ray free electron laser device in April this year. The devices in Shanghai mainly work in the hard X-ray band. The devices in Dalian mainly work in the soft X-ray band. After the two devices are built, they will form a very good complementarity and echo relationship in the geographical area and the use band. Technological innovation and the implementation of innovation-driven development strategies are of paramount importance.
In the future, “Dalian Advanced Light Source†will become an indispensable tool for promoting China's scientific and technological progress, an important support and guarantee for promoting the construction of a clean energy national laboratory, and also to revitalize the development of the Northeast region and promote the construction of an innovative city in Dalian. only way.

If the land hardness is normal,and just use 200mm,300mm back reamer,the one-gun-distance is 150 meter and it's very easily.
If the land harness is normal,and the back reamer size reach 400mm,the one-gun-distance can be 150 meter but the operator need to pay high attention to the rig to see all the digital such as the rotation pressure and other.
If the back reamer size reach 500mm,600mm,the one-gun-distance can only be 90 meter.
Remark:One-gun-distance means the distance of drill bit go from one side and come out from the other size.Please see below explanation.
