Accurate determination of dielectric properties in small, high-permittivity dielectric cylinders
Tagdulang, Nikki; Krkotic, Patrick; Díez, A.; Pont Montaner, Montserrat; O'Callaghan Castellà, Juan Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2022)
Comunicació de congrés
Accés obertWe describe a method for performing cryogenic permittivity and loss tangent measurements of small (few mm), high-permittivity dielectric cylinders used in surface impedance measurement of superconductors. We combine the ... -
Algorithm for resonator parameter extraction from symmetrical and asymmetrical transmission responses
Krkotic, Patrick; Gallardo Moix, Queralt; Tagdulang, Nikki; Pont Montaner, Montserrat; O'Callaghan Castellà, Juan Manuel (IEEE Microwave Theory and Techniques Society, 2021-08)
Article
Accés obertWe describe an algorithm capable of extracting the unloaded quality factor and the resonant frequency of microwave resonators from vector S-parameters. Both symmetrical (Lorentzian) and asymmetrical (Fano) transmission ... -
Determination of pumping and dynamic vacuum properties of conductive quaternary alloy of TiZrVAg non-evaporable getter
Valizadeh, Reza; Hannah, Adrian N.; Malyshev, Oleg; Hsiung, G.Y.; O'Callaghan Castellà, Juan Manuel; Pont, Montse; Tagdulang, Nikki (Joint Accelerator Conferences Website (JACoW), 2022)
Text en actes de congrés
Accés obertNon Evaporable Getter (NEG) coating has been employed extensively in the particle accelerator especial-ly where the vacuum conductance of the vessel is se-verely restricted and ultra-high vacuum condition is required. NEG ... -
Evaluation of the nonlinear surface resistance of REBCO coated conductors for their use in the FCC-hh beam screen
