In Feitian, the tianzhou-4 cargo spacecraft mainly researched by the eighth Academy of China Aerospace Hi-Tech Holding Group Co.Ltd(000901) group flew to Tianhe, and the first C919 large aircraft to be delivered successfully made its first flight test;
Luminescence, Shanghai Institute of Optics and mechanics of Chinese Academy of Sciences has taken a key step in domestic meter scale diffraction grating, breaking through the “neck” device;
“Core” fire, Semiconductor Manufacturing International Corporation(688981) first quarter revenue increased by more than 60% year-on-year, and important chip manufacturing enterprises maintained more than 90% of production capacity
In Shanghai, which is building a science and technology innovation center with global influence, science and technology personnel do not stop under the epidemic, strive to ensure that large scientific devices do not stop, major national tasks do not stop, and important strategic enterprises do not stop the chain.
glow: break through the “neck” and move towards the “hundred beat tile”
The total power radiated by one sun to the earth is concentrated in one hair, which is equivalent to 1 petwatt. The 100 petwatt ultra short and ultra strong laser device being developed in Shanghai is one of the important devices of Zhangjiang photon science device cluster.
Among them, the size reaches 1.6m × The 1.05M (bidirectional meter level, diagonal close to 2m) pulse compression grating is not only the key device of the system, but also the “neck” element that must be broken through to support the device to achieve the international leading level.
“Although there are many existing grating preparation technologies outside China, none of them can reach such a large size; we have put forward a new scheme of ‘full aperture large area reflective static exposure technology’, and have tackled key technical problems for more than one year.” Shao Jianda, Party Secretary of the Shanghai Institute of Optics and mechanics of the Chinese Academy of Sciences, said.
In order to realize the preparation ability of large aperture grating, it is necessary to make the off-axis mirror with large aperture, high precision and ultra-low defects extremely “smooth”. “This mirror weighs about 900kg, which is almost as large as the projection screen, but it has extremely high requirements for the macro to micro full frequency band error of the mirror.” Said Wei Chaoyang, a researcher at the Shanghai Institute of Optics and mechanics of the Chinese Academy of Sciences.
In the critical period, the members of the project team took the initiative to isolate in the Institute, eat and live in the laboratory before sealing and control, and have been fighting for nearly two months.
Today, the key problem of instability has been successfully solved. “China is the first country to realize the output of 10 petwatts and open to users. Now it is moving towards 100 petwatts. This global science and technology ‘Competition’ will not be delayed by the epidemic.” Wei Chaoyang said.
operation: “laying eggs along the way”, efficient transformation
In the tumor proton center of Ruijin Hospital Affiliated to Shanghai Jiaotong University, the clinical trial of the first domestic proton treatment demonstration device, a precision cancer treatment device in the international frontier, is being carried out in an intense and orderly manner. During the epidemic period, the clinical trial of 180 degree rotating beam treatment room was carried out as scheduled.
This is an important project of strategic cooperation between the Chinese Academy of Sciences, the Ministry of science and technology, the National Health Commission and the Shanghai municipal government. “Grinding a sword in ten years” has realized the leap of domestic proton therapy devices from “0” to “1”. “We entered the closed-loop state in March, racing against time to tackle key components, commissioning and other problems.” Chen Haitao, vice president of Ruijin Hospital, said.
This is due to the efficient transformation mechanism of the large scientific device “laying eggs along the way”. Chen Haitao said that this is the result of the transformation of the big scientific device – the “Nautilus” of Shanghai synchrotron radiation light source. “It is not only a big scientific facility, but also a medical product that serves the vast number of Lbx Pharmacy Chain Joint Stock Company(603883) , and breaks the” neck “monopoly.” Among them, China’s first 180 degree rotating frame can accurately irradiate the tumor site at more angles, avoid damaging normal tissues, and bring better treatment options and choices to tumor patients.
Although it is inevitable that it will be affected by the epidemic, the large scientific device group gathered in Shanghai is still non-stop. In March, the commissioning of Shanghai soft X-ray device made continuous breakthroughs; Hard x-ray devices not far away have also made important progress. On April 30, the prototype of superconducting acceleration module completed the second general assembly and handed over for level test, marking the completion of phase work tasks.
stabilize the “chain”: the production capacity exceeds 90%, and the “core” fire does not go out
Chip, known as “industrial grain”, represents the most sophisticated process in the manufacturing field. In Shanghai, where the scale of integrated circuit industry accounts for a quarter of the country, the production lines of leading enterprises have not stopped since the outbreak of this round of epidemic.
The chip manufacturing plant needs 24 hours without shutdown. 6000 people were retrograde stationed in the factory, tens of thousands of tons of photoresist “charter flights” arrived in Shanghai, the “24-hour supply chain defense war” was launched, and dozens of equipment manufacturers were retrograde accompanied… In Huahong group, the supply chain of four bases and six production lines was stable, a batch of containers carrying chip production materials came in, and trucks carrying car chips and power devices moved.
On May 12, the first quarter financial report of Huahong semiconductor was released, and the sales revenue reached a record high of US $594.6 million, a year-on-year increase of 95.1%. “With the support of the competent authorities and all parties, coordinate and overcome the adverse effects of the epidemic, make careful deployment in advance, and take measures to fight the epidemic and ensure production. This is the result of teamwork, efficient operation, ensuring supply chain and stable production.” Tang Junjun, President and executive director of Huahong semiconductor, said.
In order to help science and technology enterprises resume work and production and tide over difficulties, the Shanghai Municipal Commission of science and technology played a supporting role in fiscal and tax policies. Shanghai Science and Technology Co., Ltd. was founded to ensure the orderly operation and construction of major science and technology infrastructure. The Municipal Commission of economy and Information Technology issued a number of “white lists” for resumption of work and production.
“Under the epidemic, key chip manufacturing enterprises in Shanghai have maintained more than 90% of their production capacity. Semiconductor Manufacturing International Corporation(688981) , Huahong group and Jita semiconductor have maintained full production, driving a number of supporting enterprises in the industrial chain such as equipment, materials and sealing and testing to speed up the resumption of work.” Wu Jincheng, director of the Shanghai Municipal Commission of economy and information technology, said.
