Squid 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 کاملA cryogenic current comparator for beam diagnostics in the FAIR project
A cryogenic current comparator(CCC) is based on the properties of ideal superconductors to expel magnetic flux from the bulk material through shielding currents on the surface of the material. As this effect is only dependent on the magnetic field, the CCC allows measuring the magnetic field, e.g. generated by a passing ion beam, they can be measured non-destructively with a high precision. In ...

TESLA, a 33 km long 500 GeV centre-of-mass energy superconducting linear collider (upgradeable to 800 GeV) with an integrated X-ray FEL facility of 0.1 nm wave length, has been proposed by an international collaboration to be built at DESY. The backbone of this collider are more than 21000 superconducting 9-cell RF cavities, operated at 1.3 GHz with 5 Hz beam repetition rate, and about 800 supe...
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...

The Tera-eV Energy Superconducting Linear Accelerator (TESLA), a 32 km long superconducting linear electron/positron collider of 500 GeV (upgradeable to 800 GeV) centre of mass energy, presently in the planning phase at DESY, will consist of about 21000 superconducting RF 9-cell cavities of pure Niobium. Each cavity of about 1 m length has to be cooled in a 2.0 K helium bath and operated at 1.3...
