Cryogenic Current Comparator for Absolute Measurements of the Dark Current of Superconducting Cavities for Tesla
A measurement System for detecting dark currents, generated by the TESLA cavities is proposed. It is based on the cryogenic current comparator principle and senses dark currents in the nA range. Design issues and the application for the CHECHIA cavity test stand are discussed.
متن کاملSquid Based Cryogenic Current Comparator for Measurements of the Dark Current of Superconducting Cavities
A newly high performance SQUID based measurement system for detecting dark currents, generated by superconducting cavities for the upcoming X-FEL project at DESY Hamburg, is proposed. It makes use of the Cryogenic Current Comparator principle and senses dark currents in the pA range with a measurement bandwidth of up to 70 kHz.
متن کاملIsolated ramping current sources for a cryogenic current comparator bridge
The design and perfonnance of a pair of highly isolated ramping and reversing direct-current sources for use with a cryogenic current comparator resistance bridge and dc superconducting quantum interference device (SQUID) detector are described. The current sources are floating and isolated from one another, and are internally programmed to reverse the output current while maintaining the SQUID...
متن کاملA Cryogenic Current Comparator for Fair with Improved Resolution *
A Cryogenic Current Comparator is a highly sensitive tool for the non-destructive online monitoring of continuous as well as bunched beams of very low intensities. The noise-limited current resolution of such a device depends on the ferromagnetic material embedded in the pickup coil of the CCC. Therefore, the main focus of research was on the low temperature properties of ferromagnetic core mat...
متن کاملDark Current in Superconducting Rf Photoinjectors – Measurements and Mitigation
Unwanted beam can cause beam losses and may produce acute or chronic damages of the accelerator. Furthermore it can considerably disturb experiments or increase its back-ground. The operation of the superconducting RF photo gun at the ELBE accelerator has delivered the first experimental information on that topic for this gun type. It was found, that dark current is an important issue, similar ...
