Publisher: Wiley-Blackwell

About this book
The physics and theory underlying electron beams and microwave vacuum electronics This book focuses on a fundamental feature of vacuum electronics: the strong interaction of the physics of electron beams and vacuum microwave electronics, including millimeter-wave electronics. The author guides readers from the roots of classical vacuum electronics to the most recent achievements in the field, exploring both the physics and the theory underlying electron beams and devices of vacuum high-frequency electronics. Special attention is devoted to the physics and theory of relativistic beams and microwave devices. Readers gain a deep understanding of the topic as well as the theory and applications of specific devices.The book consists of two parts. Highlights of Part One, "Electron Beams," include: Motion of charged particles in static fieldsTheory of electron lensesElectron beams with self fields and problems in the formation and transport of intense electron beamsPart Two, "Microwave Vacuum Electronics," features coverage of such topics as: Physics and theory of the interaction of electron beams with electromagnetic fields in quasi-stationary systems (e.g., diodes, klystrons)Systems with continuous interactions (e.g., traveling wave tubes, backward wave oscillators)Crossed-field systems (e.g., traveling wave and backward wave tubes of M-type, magnetrons, crossed-field amplifiers, MILO)Systems based on stimulated radiation of classical electron oscillators (e.g., classical electron masers, including gyrotrons, classical auto-resonance masers, free-electron lasers)The author clearly states problems and then explores appropriate models, approximations, and derivations. This book, based on the author's own research and lectures, is recommended for students, researchers, and engineers working in such fields as electron beam technology, high-frequency vacuum devices for communications, radar, controlled fusion, charged particle accelerators, materials processing, and biomedicine.

Emerging applications of vacuum-arc-produced plasma, ion, and electron beams

Creator: Efim Oks, Ian G. Brown, North Atlantic Treaty Organization. Scientific Affairs Division | Science - 2002

The accelerated Cu:" beam current up to 6 mA has been already obtained. 3. E- MEWA experiment The idea of e-MEEVA ion source consisted of combining an electron beam, a vacuum arc ion source, and a plasma drift tube, to provide the charge ...

Publisher: Springer

About this book
The field of vacuum arc plasma physics and technology is undergoing a renaissance, and this book describes novel applications of plasmas and ion/electron beams formed from vacuum arc discharges, especially in less conventional or emerging scientific areas such as new perspectives on vacuum arc phenomena, generation of high-charge-state metal ions, heavy ion accelerator injection, multi-layer thin film synthesis, biological applications, generation of high-current / high-density electron beams, and more.

    Plastic vacuum hose

    I would have preferred to buy a nylon reinforced hose for durability, but the price difference dictated that it was not good value. This hose works perfectly well and doesn't kink easily. The quality is such that I anticipate a life of only about 5 years before it starts to split and needs duct tape repairs, as my last hose. My original nylon and wire reinforced Beam hose lasted 14 years. It's a decent hose for the price, but not the same high quality that is available for mega bucks. 3/5 A.

    Lightweight But Perfect for My Dog

    I bought this for a second hose to store near where I vacuum my dog. Another reviewer is correct: The hose is not as sturdy as the one that came with the unit originally, but the light weight is an advantage in my case. And for the price, you can't expect it to be the quality of the original. 5/5 Alice (Wisconsin) - See all my reviews Amazon Verified Purchase(What's this?)

    Overpriced junk with ZERO customer service

    As a frequent Amazon buyer and reviewer, I rely on honest reviews when making a purchase. I hope my review prevents someone from making the mistake of buying this piece of trash. This was purchased through a 3rd party seller who seemed to be honest and reliable. I even went to their website and read all of the glowing reviews (which I now KNOW for a FACT are completely fabricated) and boasts of exceptional customer service. What a joke! This hose is very, very poorly made:1) The hose is constructed from an extremely thin plastic. With minimal movement, it twists upon itself and kinks, completely cutting off suction. It is more prone to kinks than imaginable. I can hardly get a few feet without a kink.2) The hose texture is rough and beats the heck out of everything it brushes against. It is also very loud as it moves across the floor. (I am STILL waiting for my exorbitantly priced sock cover to arrive, if it ever does)3) The white color leaves marks... 1/5 Jessica Farrone (Fairfield, CT United States) - See all my reviews, November 6, 2010

    Nearly Perfect in every way.

    Great quality hose & at a great price. My attachment doesn't fit perfectly in the handle end, so it goes in further than the button lock but still makes a perfect vacuum seal. So, my vacuum works great again. I'll buy it again. 5/5 James J. Zitis - See all my reviews, August 14, 2009

    Hair causes it to seize

    The seal on the roller ends needs substantial imprvement because pet and other hair gets caught there and eventually the roller seizes up and it all has to be disassembled to clean which is annoying and time consuming.

    Excellent replacement for original brush

    After 17 years, the original air-driven brush gave up the ghost. This replacement seems to be almost identical to the original, or perhaps even a bit better.

    great product for in house vacs

    This is a really great product, even though its a little older model. i know other newer models are available (Zoom, etc) but this one still works and works really well. easy to use and goes right under the chairs, sofas and stuff around the house. Nice wide brush comparable to a regulat vacuum. i was concerned about the potential noise.... but its quieter than most upright vacs. It sucks up pet hair well and almost everything else visible on carpets and hard floors, provided it goes up the tube. its light and easily manouverable. Dont expect the really deep down cleaning you might get with a high line $300-400 powerful upright machine, but do expect an easy to use syatem that for 90% of what you need, does a great job. We are so happy with it that while we were going to also buy an upright, we chose not to, as we really dont need it. the ding is for a need to pull out the assembly once in a while to remove the stuff that gets wrapped around the rollers, but it really isnt a... 4/5 big ears "sniffy" (pittsburgh pa) - See all my reviews Amazon Verified Purchase(What's this?)

    Good Service, ...But

    Product was delivered almost immediately after ordering. Recieved it in just 2 or so days.But, product was not configured as described in ordering process. It required a modificationand part that was not in the original deliver. It was necessary for me to contact the vendor.It took at least 3 calls to reach the necessary support individual to corredt the problem. Ithen had to wait 3/4 more days for the necessary part (so much for the initial prompt delivery).Vendor was supportive, but the extra steps/hoops should not have been necessary.The product, once modified, is performing as expected. And, hopefully, will give me at least 9 yearsof service as my original purchase did. 4/5 S. Gannon - See all my reviews, February 9, 2012

    Poor quality generic hose and tools

    The hose is pretty good and works well. The power head appears to be fairly generic (no name or label) but seems to work OK so far. All the additional tools are fairly cheaply constructed and not very high quality, but they're acceptable. No documentation came with the product (no user's manual, warranty registration, etc.). Have only had it about a week. Hope it will hold up long-term.UPDATE: Hose connects too loose to the wall valve! Keeps falling out! This happens to all the wall valves. Our old hoses fit snug. I'm not sure if there is a work-around. Very frustrating. On top of that, the hose kinks like crazy. Worse similar hose I've ever owned. 2/5 Jeffrey R.
