Mr. Ye Minghan, academician of the Chinese Academy of Engineering, famous experimental high-energy physicist, expert in particle detection technology, academic director of the China Advanced Science and Technology Center, outstanding member of the China Democratic League, former chairman of the High Energy Physics Branch of the Chinese Physical Society, chairman of the Nuclear Electronics and Detection Technology Branch of the Chinese Nuclear Society, and director of the Institute of High Energy Physics of the Chinese Academy of Sciences, passed away at 12:30 on October 4, 2024 in Beijing at the age of 99.
Mr. Ye Minghan is one of the pioneers of China's low-energy accelerator, low-energy nuclear physics experiments, particle control and measurement technology and high-energy physics experiments, and is one of the main leaders of the large-scale scientific research projects "Beijing Positron Collider (BEPC) and Beijing Spectrometer (BES)", and has made important contributions to China's construction of nuclear physics and high-energy physics experimental bases and occupies a place in the field of high-energy physics experimental research in the world.
In the 50s of the 20th century, he participated in the development of the first and second charged particle accelerators (electrostatic accelerators with an energy of 700 kiloelectron volts and 2.5 megaelectron volts) in mainland China, and was responsible for their operation and improvement, and obtained a number of important results. Later, he took the lead in developing a variety of particle detectors, carried out the first batch of nuclear physics experiments on the mainland, and made physics work of international level. In the 70s of the 20th century, he and Xiao Jian presided over the development of particle detectors commonly used in high-energy physics experiments such as multifilament proportional chamber and drift chamber, and took the lead in realizing the computer online data acquisition of multifilament proportional chamber in China. In 1982, he presided over the construction of the Beijing spectrometer, a large-scale high-energy physics experimental particle detection device, which was completed in 1988 and obtained a series of internationally significant achievements such as accurate mass measurement of ceramic leptons. He has won the special prize of the National Science and Technology Progress Award and other awards.
Mr. Ye Minghan is patriotic, dedicated, rigorous and realistic, indifferent to fame and fortune, and selfless dedication. He has trained a large number of outstanding students, most of whom have become the backbone of high-energy physics and nuclear physics research. He was very concerned about the continuous development of high-energy physics in mainland China, and put forward many useful suggestions for the construction of BEPCII./BESIII., which laid a solid foundation for obtaining better physical results. His death is a great loss to the mainland's scientific and technological community! We mourn and deeply cherish the memory of Mr. Ye Minghan! His spirit will always be with us.
Mr. eternal, style lasts forever!

The reporter found that in April this year, Academician Ye Minghan also donated 3 million yuan to the University of Chinese Academy of Sciences (hereinafter referred to as UCAS) Education Foundation to establish the "Ye Minghan Fund" to reward young researchers from the Institute of High Energy Physics of the Chinese Academy of Sciences (hereinafter referred to as the Institute of High Energy Physics) and support them to carry out research on high energy physics.

An interview with Academician Ye Minghan
Remembering Ye Lao
My Family, My Country丨Interview with Ye Minghan, Academician of the Chinese Academy of Engineering
Ye Minghan, academician of the Chinese Academy of Engineering, is one of the pioneers of high-energy physics research in mainland China. In the spring of 1950, the state proposed that the newly established Institute of Modern Physics of the Chinese Academy of Sciences should take the lead in developing an important foundation for high-energy physics: accelerators.
At the end of 1979, in order to build the mainland's own collider as soon as possible, Ye Minghan went to Princeton University in United States as a visiting scholar. His experience in foreign countries made him feel the gap between China and the United States, but he was also more convinced that "as long as the conditions allow, we can do the same".
China has gained a place in the world's high-tech sector
"China must have a place in the world's high-tech sector." These are the words of Deng Xiaoping when he visited the Positron Collider in Beijing. Under the research of Ye Minghan and other physicists, the Beijing Positron Collider has achieved a series of internationally advanced level achievements and ranked among the top in the world. This breakthrough has also made great progress in related fields and driven the related industrial chain.
Ye Lao: If you can't make up your mind about what I have, I'll help you settle it. Later, we proposed that your temperature and the temperature to be processed should be constant, how can you achieve a constant temperature? That temperature is also well controlled, and the whole room is at this temperature.
Reporter: This is such a high requirement, for the factory at that time, can it be completed?
Ye Lao: It's done.
Reporter: So it's not just this field that we have studied, which has driven the relevant industrial chain, and the overall level is rising.
Ye Lao: High-tech industrial chain.
The physicist is also a big · Potter fan
Reading is a habit that Ye Minghan has maintained since he was a child, and the bookcase has become the largest piece of furniture in his living room and study. The experience of exchange abroad for many years made Ye Lao develop the habit of reading United Kingdom literature. The Harry · Potter series of books, because of their popularity and interest, have become Ye Lao's leisure reading.
A scientific bloodline passed down from generation to generation
For Mr. Ye Minghan, an academician of the Chinese Academy of Engineering, the greatest influence on him was his uncle Ye Qisun, who was also a physicist. Ye Qisun has trained 79 academicians in his lifetime, and his student Qian Sanqiang is Ye Minghan's mentor.
From 1929 to 1937, the Department of Physics at Tsinghua University was full of masters. It is this strong scientific research atmosphere and enthusiasm to serve the family and country that has passed down the research of physics from generation to generation.
Wang Ning: His love for students is not what ordinary teachers ask them to do, but love from the heart?
Ye Minghan: Yes, love. At that time, there was a worker in the physics department who was very smart, and finally my uncle found out that he was smart, so he trained him to take care of the experimental equipment, and he was very clever and could repair some of it. So this person used to be called a worker, and he became an assistant. He had a lung disease, and my uncle paid for him to recover.
Wang Ning: Mr. Ye has sponsored a lot of students, right?
Ye Minghan: For some poor students, he has more money, so he subsidizes them.
