A Certain Scientific Accelerator Vol 3

"The new spin-off series of A certain scientific railgun"--Page 4 of cover.

Accelerator, the most powerful psychic in Academy City, is quietly recovering from his injuries when trouble literally lands in his bedroom. A group of anti-evil zealots who call themselves “DA” are causing havoc, and it could threaten the city―not to mention the entire world! Although he hates to be bothered, a world-shaking threat may be enough to get Accelerator out of bed…especially if it involves the adorable Misaka Mikoto clone, “Last Order.”

While Accelerator recuperates, the explosive battle in Academy City rages on--all four sides of it! As Estelle rushes to the fray, Yomikawa Aiho and the soldiers of Anti-Skill struggle to subdue their extremist splinter group DA. DA's stockpile of secret weapons threatens to crush Anti-Skill... until Scavenger arrives. The four girls of Scavenger are as powerful as they are ruthless, and their intervention is sure to wreak havoc on the tires of war.

Over the last half century we have witnessed tremendous progress in the production of high-quality photons by electrons in accelerators. This dramatic evolution has seen four generations of accelerators as photon sources. The 1st generation used the electron storage rings built primarily for high-energy physics experiments, and the synchrotron radiation from the bending magnets was used parasitically. The 2nd generation involved rings dedicated to synchrotron radiation applications, with the radiation again from the bending magnets. The 3rd generation, currently the workhorse of these photon sources, is dedicated advanced storage rings that employ not only bending magnets but also insertion devices (wigglers and undulators) as the source of the radiation. The 4th generation, which is now entering operation, is photon sources based on the free electron laser (FEL), an invention made in the early 1970s. Each generation yielded growths in brightness and time resolution that were unimaginable just a few years earlier. In particular, the progression from the 3rd to 4th generation is a true revolution; the peak brilliance of coherent soft and hard x-rays has increased by 7-10 orders of magnitude, and the image resolution has reached the angstrom (1  = 10-10 meters) and femto-second (1 fs = 10-15 second) scales. These impressive capabilities have fostered fundamental scientific advances and led to an explosion of numerous possibilities in many important research areas including material science, chemistry, molecular biology and the life sciences. Even more remarkably, this field of photon source invention and development shows no signs of slowing down. Studies have already been started on the next generation of x-ray sources, which would have a time resolution in the atto-second (1 as = 10-18 second) regime, comparable to the time of electron motion inside atoms. It can be fully expected that these photon sources will stand out among the most powerful future science research tools. The physics community as well as the entire scientific community will hear of many pioneering and groundbreaking research results using these sources in the coming years. This volume contains fifteen articles, all written by leading scientists in their respective fields. It is aimed at the designers, builders and users of accelerator-based photon sources as well as general audience who are interested in this topic.

Touma Kamijou just can't catch a break. He might live in Academy City, a place full of more super powered students than you can shake a stick at, but his only superpower is his supernatural lack of luck. He wants nothing more than to keep a low profile, but when a girl named Index comes into his life, it gets more complicated and dangerous than ever!
