{"product_id":"smith-purcell-radiation","title":"Smith-Purcell Radiation","description":"Smith-Purcell radiation is the name given to the radiation produced when a charged particle beam, usually electrons, passes close to the surface of a metallic grating. The wavelength of the emitted radiation depends on the period of the grating and on the angle of observation. This makes this phenomenon a very useful tuneable source of radiation in the far-infrared (or THz) part of the spectrum, where tuneable sources are scarce. Moreover, a spectral analysis of the radiation can be used to reconstruct the time profile of the very short (picosecond or sub-picosecond) electron bunches that gave rise to this radiation. This is a parameter that is of interest to accelerator designers and users. \n\nThe book is aimed primarily at experimentalists but starts with a relatively simple theoretical description of the origin of this radiation and then discusses its application either as a beam diagnostic tool or as a tuneable source of THz radiation. There is also a brief overview of other THz sources in order to allow the reader to assess the advantages of Smith-Purcell radiation.","brand":"Oxford University Press","offers":[{"title":"Default Title","offer_id":54249473573208,"sku":"9780198951346","price":93.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9780198951346.jpg?v=1781702119","url":"https:\/\/agendabookshop.com\/products\/smith-purcell-radiation","provider":"Agenda Bookshop","version":"1.0","type":"link"}
