ATLAS B0 toroid model coil test at CERN

ATLAS B0 Toroid Model Coil Test at CERN

The ATLAS superconducting magnet system consists of a Barrel Toroid, two End-Cap Toroids and a Central Solenoid. The Barrel Toroid, with overall dimensions of 20-m diameter by 26-m length, is made of eight individual coils symmetrically assembled around the central axis with a warm structure. The system is presently under construction in industry. In order to verify the construction concepts a ...

The BOO model coil in the ATLAS magnet test facility - Applied Superconductivity, IEEE Transactions on

A 1-m sim model coil has been developed to investigate the transport properties of the three aluminumstabilized superconductors used in the ATLAS magnets. The coil, named BOO, is also used for debugging the cryogenic, power and control systems of the ATLAS Magnet Test Facility. The coil comprises two double pancakes made of the Barrel Toroid and End-Cap Toroid conductors and a single pancake ma...

EUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH Laboratory for Particle Physics (ECR) QUENCH INDUCED PRESSURE RISE IN THE COOLING PIPES OF THE ATLAS BARREL TOROID MODEL

The ATLAS superconducting magnet system consists of a Barrel Toroid, two EndCap Toroids and a Solenoid. Eight individual racetrack coils will be assembled to form the Barrel Toroid with overall dimensions of 26 m length and 20 m diameter. In order to verify the design concept a 9 m long short version of a single Barrel Toroid coil was built. A test program was conducted at the CERN cryogenic te...

B1 and B0 mapping of a micro helix Coil at 9.4T

Introduction The magnetic field produced per unit current, B1, and B0 mapping are important criteria when evaluating the performance of micro coils in NMR microscopy [1]. To increase the coil B1 across the sample and achieve high MR image SNR, RF coils should be placed as close as possible to the NMR sample. Bringing coils close to materials with different susceptibility, results in inhomogenei...
