Superconducting Properties of Niobium Radio-Frequency Cavities
ISBN: 9783843387439 / Angielski / Miękka / 244 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Superconducting radio-frequency (SRF) cavities are used to increase the energy of a charged particle beam in particle accelerators throughout the world. Bulk niobium is the material of choice to fabricate SRF cavities and their performance at cryogenic temperatures is characterized by a non-linearity of the surface resistance as a function of the RF field, in absence of field emission, which limits the operational accelerating gradient. This book presents the results on the investigation of such non-linearity in cavities which received different surface and bulk treatments as well as cavities...

Time Domain Analysis And Multiobjective Optimization In Rf Engineering
ISBN: 9783838345659 / Angielski / Miękka / 204 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This work comprise two distinguish arguments, both important in RF engineering. The first one exploits the Method of Moments in Time Domain (MoM-TD). Such method can be implemented, as for frequency domain, either resorting to a thin wire approximation or to a surface patch model. For heterogeneous structures both implementations might be needed, and the problem of the attachment between a perfectly conducting thin wire and a perfectly conducting surface is hence relevant. In this work attachment modes are introduced in MoM-TD and a uniform formulation of the method itself is presented for...
