An Indispensable Truth de Francis Chen

An Indispensable Truth

Autor Francis Chen
en Limba Engleză Hardback – 22 apr 2011

Relevanța lucrării An Indispensable Truth pentru cercetători și studenții la fizică nucleară este imediată, oferind fundamentul teoretic necesar înțelegerii tranziției de la experiment la implementarea industrială a energiei de fuziune. Observăm că Francis Chen nu se limitează la o expunere tehnică, ci ancorează necesitatea fuziunii hidrogenului în realitatea stringentă a crizei climatice. Structura cărții este una progresivă: debutează cu o evaluare imparțială a schimbărilor climatice și a limitărilor actuale ale energiilor regenerabile, pentru ca ulterior să exploreze în profunzime conceptele de „tokamak” și evoluția acestora pe parcursul a jumătate de secol. Suntem de părere că această lucrare extinde cadrul propus de Fusion de Garry McCracken cu date noi din ultimele două decenii de cercetare, oferind o perspectivă mult mai optimistă asupra fezabilității ingineriei nucleare. În timp ce alte titluri similare, precum The Fairy Tale of Nuclear Fusion de L. J. Reinders, adoptă o poziție sceptică privind intervalul de timp necesar implementării, Chen utilizează expertiza sa vastă pentru a demonstra că fuziunea este o soluție inepuizabilă și atingibilă. Această ediție publicată de Springer se raportează direct la opera sa anterioară de referință, Introduction to Plasma Physics and Controlled Fusion. Dacă manualul din 1974 punea bazele teoretice ale plasmei, volumul de față reprezintă o sinteză matură care face pasul către aplicațiile practice. Stilul este riguros, specific unui cercetător cu cinci decenii de activitate, dar accesibil celor care doresc să înțeleagă costurile și termenele reale ale acestui proiect monumental.

Descriere scurtă

Recent books have raised the public consciousness about the dangers of global warming and climate change. This book is intended to convey the message that there is a solution. The solution is the rapid development of hydrogen fusion energy. This energy source is inexhaustible and, although achieving fusion energy is difficult, the progress made in the past two decades has been remarkable. The physics issues are now understood well enough that serious engineering can begin.The book starts with a summary of climate change and energy sources, trying to give a concise, clear, impartial picture of the facts, separate from conjecture and sensationalism. Controlled fusion -- the difficult problems and ingenious solutions -- is then explained using many new concepts.The bottom line -- what has yet to be done, how long it will take, and how much it will cost -- may surprise you.

Francis F. Chen's career in plasma has extended over five decades. His textbook Introduction to Plasma Physics has been used worldwide continuously since 1974. He is the only physicist who has published significantly in both experiment and theory and on both magnetic fusion and laser fusion. As an outdoorsman and runner, he is deeply concerned about the environment. Currently he enjoys bird photography and is a member of the Audubon Society.

Recenzii

From the reviews:
“The ‘indispensable truth’ is that Chen … has written what may well be recognized as the definitive retrospective on the promise of endless supplies of cheap, clean nuclear energy from fusion, offering the prospect of realizing the promise at last. … It is stylishly written, designed, and illustrated to appeal to general readers … . Chen is in his comfort zone as he tells his story, and the indispensable truth is that it is just that–indispensable! Summing Up: Highly recommended. All levels/libraries.”­­­ (L. W. Fine, Choice, Vol. 49 (3), November 2011)
"With An Indispensable Truth: How Fusion Power Can Save the Planet, Frank Chen has provided a sweeping perspective on fusion energy. He covers everything from climage change to plasma instabilities. On climate change and energy, the view is best from 30 000 feet: The book provides a good high-level overview of the issues at stake...On fusion plasma physics, Chen's area of expertise, An Indispensable Truth provides an intuitive, up-close explanation of exciting recent advances and future challenges...An Indispensable Truth provides an exciting whirlwind tour of energy issues and technologies, with particular insight into fusion. Chen is correct to emphasize the tremendous progress that has been made in fusion research. ITER will produce hundreds of millions of watts of thermal energy from fusion, for periods of up to an hours. However, it remains for the world, and in particular the US, to decide if we will develop fusion into a practical energy source. We will need it." (Physics Today, Volume 65, Issue 2, February 2012)

Notă biografică

Francis F. Chen, known as Frank in the physics community, got his B.A. from Harvard Observatory in 1950. His all-star oral committee consisted of famous astronomers Harlow Shapley, Bart J. Bok, Donald Menzel, and Earl Whipple. With pulsars and quasars still undiscovered, he switched to High Energy Physics, receiving his Ph.D. from Harvard in 1954. He had been sent by his adviser, Nobelist Norman Ramsey, to Brookhaven National Laboratory, where he worked on the Cosmotron and wrote the first experimental thesis for energies at or above 1 GeV. To avoid the Korean War draft, he then went to work for the astronomer Lyman Spitzer, Jr., who had just started the classified Project Matterhorn at Princeton University. This was one of four initial projects in the U.S. to tame the hydrogen bomb to make energy peacefully from the same reaction. In 1954, Chen was one of the first 15 employees at what is now the Princeton Plasma Physics Laboratory (PPPL). Project Matterhorn started in two old buildings, one formerly a rabbit hutch, and the other a horse operating room. Chen inherited the Model B1 Stellarator, built by James van Allen of the famous van Allen radiation belts around the earth. With the B1, Chen was the first to show that electrons could be trapped by a magnetic field for millions of traverses. By then, it was clear that fusion would require trapping a plasma, a hot, ionized gas of electrons and ions, and not just electrons. Subsequent Model B stellarators, however, failed to do this for longer than milliseconds. Realizing that stellarators were magnetic bottles that were curved and not straight, he convinced Spitzer to allow him to build straight machines to isolate the problem, even though these would have leaks at the ends. Chen then built the L-1 and L-2 machines with straight magnetic fields. Experiments on these showed that the plasma was lost by turbulence, and these random motions were aligned along the magnetic field, with wavelengths longer than any plasma waves known at that time. While on sabbatical in Paris, Chen figured out what these new waves were. They are now known as resistive drift waves and were discovered simultaneously in Russia by Sagdeev and Pogutse. In L-2, Chen and Mosher showed how this turbulence could be suppressed by magnetic fields that were not totally straight but had what is called shear. Modern magnetic bottles (called tokamaks), using advanced methods of stabilization, can hold a hot plasma for minutes. In 1969, Chen went from Princeton to UCLA in California, where he organized an academic program in plasma physics. He wrote the first undergraduate textbook in this field in 1973. Soon after, however, powerful lasers were invented, opening up a whole new field of research. Chen then left magnetic fusion to help start the field of laser fusion. He built the first laser at UCLA. In basic experiments, he and his students were among the first to study Brillouin and Raman scattering, two instabilities that cause problems even in laser-produced plasmas. This interesting field led to John Dawson's discovery of plasma accelerators, which can shrink the size of machines for high-energy particle research by a factor of 1000! Chen recruited C. Joshi, whose experimental acumen has led his group to spectacular successes. Meanwhile, Chen left the effort to join yet another nascent field: low-temperature plasma physics. This involves partially ionized gases which include neutral atoms as well as ions and electrons. This complexity had led to its reputation as dirty science. By developing helicon plasma sources, which are magnetized, Chen showed that radiofrequency gas discharges contain very interesting physics which can be treated in a logical and interesting manner. Chen's 57-year career in plasma physics can be divided into four approximately equal parts: magnetic fusion, laser fusion and laser accelerators, low-temperature plasma physics, and plasma diagnostics. In the last of these, Chen is an authority

Textul de pe ultima copertă

Both global warming and oil shortage can be solved by controlled fusion, a clean power source that will serve mankind for millennia.The idea of hydrogen fusion as well as its difficulties are presented in non-technical language to dispel the notion that fusion is always 50 years away. This book also summarizes the evidence for climate change and explains the principles of both fossil and "green" energy sources to show that fusion is the best alternative for central-station power in the near term as well as the far future.
Praise for An Indispensable Truth: How Fusion Power Can Save the Planet:
"In this study Professor Chen outlines the underlying physics, recent progress in achieving advanced plasmas and magnetic confinement, and hopes for the future. He recognizes the difficulties that remain in engineering a fusion reactor, but he remains optimistic regarding ultimate success, yet fearful of the consequences were we to fail."- James R. Schlesinger, former Chairman, Atomic Energy Commission; Director, Central Intelligence Agency; Secretary of Defense; and Secretary of Energy
"With lots of detail and examples, Chen brings the technical topic of fusion to life, making the book a great read for scientists and nonscientists alike."- Representative Rush Holt (D-NJ)
"Professor Chen has opened the door to energy survival for our globe. His insightful analysis makes the case for fusion energy, and he conveys both its complexity and its promise. This book is a must for all those who are concerned about the energy future of our species."- Raymond L Orbach, former Undersecretary for Science, U.S. Department of Energy
"This is an important book for anyone who wishes to understand the greatest challenge we face. Frank Chen makes the science of fusion and energy clear, compelling, and hugely enjoyable."- Steven Cowley, Director and CEO, Culham Centre for Fusion Energy, United Kingdom Atomic Energy Authority
