Greg Hammet, a theoretical and mathematical physicist who promotes the integration of integrated plasma performance and the complex turbulence of a dedicated teacher, has been named a science fellow at the Department of Energy Science (DOE) 2021. . Honored and highly regarded, the award honors the remarkable achievements of physicist Hammet, a physicist at DMS Princeton Plasma Physics Laboratory (PPP), who has worked with his colleagues on the development of computerized simulations into the integrated plasma and into the inner universe.

The award, which is approved under US COMPETES law, recognizes specialists who have directly contributed $ 1 million over three years to the most innovative and selected projects in 17 DOE national laboratories.

“Under the influence of climate change, we are pursuing scientific solutions to some of the greatest challenges in our country,” he said. Energy David Turkey. I look forward to their continued success as they work to inspire and guide a variety of new scientists. The imaginary ceremony will take place on October 20, 2021.

The quote celebrates the 35th anniversary of the PPPL physicist, “In the development of numerical theory and plasma disturbances and astrophysics, and to educate and advise a diverse group of postgraduate students and early professional researchers. He is one of the three most revered.

For gossip, honor should be shared. “I am delighted and amazed by the award and I hope that my colleagues and others will be recognized for the excellent work that has been done in the merger program,” Hamet said. “It was really a team effort with visiting colleagues and graduates so I hope this award is a way for them to be recognized as well.

“We have benefited from the progress that we have made and the fact that we have begun to interact with them at seminars and conferences,” he said. “This integration plasma reflects the high quality of research to understand uncomplicated indirect variability.

Theoretical and mathematical scientists combine light elements in the form of plasma to generate energy – they use computer codes to simulate and predict the effects of turbulence in the process of multiplication. Sun and stars. Scientists around the world want to duplicate and collect energy for the sake of security and clean energy.

Violence occurs when small fluctuations in plasma plasma create eddies that can transfer heat from the thermal core of the plasma to the outer edge. By lowering the temperature in the millions of degrees Celsius where transport integration takes place, transport reduces plasma performance. While this does not preclude the stars from producing this energy, gossip and its colleagues and students have developed and implemented modern computer codes to understand the complex process of violence and enable experimentalists to cope on Earth.

Steve Cowley, director of PPP, said: In the 1990s, with Bill Dorland and other students in the Georgetown Models on Geo-liquid Models on Gero-Liquid Models, up to the present leadership, Greg Hammet has been a leader in global development. The concept of disturbance in restricted plasmas. It is an amazing contribution that revolutionized our perception. Greg has always been kind and generous to other contributors, so I am delighted that his personal impact has been recognized in this great award.

Gossip and collaborators carry out a number of activities aimed at minimizing the turbulence that causes hot particles to flow from the fusion device. These tasks range from exploring potential multi-level algorithms to accelerating cutting codes, studying the effects of plasma forming, and significantly reducing the turbulence caused by the coating of some internal walls with lithium solution. Iron as a lithium tokamak test-beta as in PPPL.

According to John Menard, deputy director of research at the PPP, their work has opened new doors to the challenge of energy integration. Greg is an expert in the concept of plasma turbulence and simulation and is well-suited for this award. In particular, I look forward to examining the role of lithium wall coatings in reducing plasma turbulence by Greg and his associates. We still do not have a basic understanding of how the conflict has been resolved, and further improvements in detention will be key to reducing the size and cost of integration, ”Menard said.

Hammet explains the work: “Using computers to solve formulas to predict plasma performance is like using computers for weather or hurricane forecasts.” “The equations describe how conditions such as air velocity and temperature affect millions of neighboring locations, and things are solved to predict what will happen in a minute, two minutes later, and so on. The weather forecasts are great for a day, but stay strong in the long run. Fortunately, we do not have to predict the “weather” of the plasma every day for integration. Over time, we need to know only the average amount of plasma rain and sunlight.

Hammet is also known as PPP. Professor Hammet, Plasma Physics Director of Plasma Physics, has been a professor at Plasma Physics for many years with a degree in Plasma Physics. Upon completing his research, he served as an excellent counselor and teacher. And a professor of astronomy at Princeton University. “Professor Hammett is a natural teacher and a very important member of the faculty of this postgraduate program. On a personal note, I can almost describe how happy it is to teach a course with Professor Gossip, to teach with him. His enthusiasm is contagious, his commitment to students is unbounded; And his ability to handle and explain complex processes is simply a gift. It is my hope that this well-deserved recognition will enable Professor Hamet to make a deeper contribution not only in research but also in teaching and consulting with future generations of researchers.

Hammet, a U.S. Air Force pilot, was born in Japan and attended 13 schools from Idaho to Georgia before graduating from Georgia High School. “My father first inspired me to do many things in physics, and my mother was very supportive of all my academic pursuits. In the 1950s, they dragged the teen race and made the car soup. As a child, I helped him repair our cars by replacing brake pads and hydraulic systems.

Time has drawn gossip into science. I was a child of Apollo landing and I felt a little too close because my father flew an F-106 that could reach higher altitudes and sometimes wore a suit. Not just an oxygen mask, but a full-fledged suit, similar to what the astronauts wore, so there were people involved with me in such things.

Hammet by PPP. In 1986, he received a bachelor’s degree in physics from Harvard University and a doctorate from Princeton in 1986. He is a professor with a professor’s degree in Plasma Physics at the Princeton program and is a Fellow of the Faculty affiliated with Printing in Program and Mathematics. As a gob scientist or research fellow, he has conducted research at the Common European Torres (Jet) Laboratory and at the University of Oxford in the United Kingdom and at the University of California at Berkeley. A Fellow of the American Physical Society, he has taught postgraduate studies since 1995 and has supervised 11 doctoral studies and taught many other students.

Gossip has written or explained more than 180 papers in scientific journals and national and international conference proceedings. His work on liquid models in the process of lint damping extends liquid equations to handle kinetic effects, is mentioned in more than 400 printed papers, and has found applications in fields such as turbulence and semiconductor plasma processing in the ionosphere.

Hammet enjoys riding a bicycle while not watching plasma, and walking and watching TV secrets with his wife, Kate, an artist becomes a craftsman who makes furniture. Their home with Little Maltese, Lily – a retired dog who visited hospital patients and schools with Kate – and Walter, an orange tab. The couple are “professional aunt and uncle. I have six siblings and four by my wife and that will keep us busy, ”he said.

Hammet looks forward to the task ahead. “I think this is a wonderful time to be united,” he said. “There are some great ideas on how to improve integration reactor designs, and computers are 100 million times more powerful than when I was a graduate student. I only spit on their abilities. We hope that just as humans used computers to design better aircraft, we will use them to design better integration tools.
