A Digital Quench Detection System for Superconducting Magnets
A system has been developed for digitally detecting superconducting magnet quenches in real time. This system has been fully tested and is completely integrated into a Vertical Magnet Test Facility (VMTF)[1] at FNAL. The digital technique used for this system relies on the application of digital signal processing (DSP) algorithms running on a native Motorola PowerPC VME processor. The performan...
متن کاملState-of-the Art Superconducting Accelerator Magnets
With the LHC the technology of NbTi-based accelerator magnets has been pushed to the limit. By operating in superfluid helium, magnetic fields in excess of 10 T have been reached in various one meter-long model magnets while full scale magnets, 15 meter-long dipoles, have demonstrated possibility of safe operation in the 8.3–9 tesla range, with the necessary, very tight, field accuracy. The pap...
متن کاملQuench simulations for superconducting elements in the LHC accelerator
The design of the protection system for the superconducting elements in an accelerator such as the Large Hadron Collider (LHC), now under construction at CERN, requires a detailed understanding of the thermo-hydraulic and electrodynamic processes during a quench. A numerical program (SPQR Simulation Program for Quench Research) has been developed to evaluate temperature and voltage distribution...
متن کاملSuperconducting Accelerator Magnets: a Review of Their Design and Training*
This paper reviews the basic mechanical designs of most of the superconducting magnets developed for high energy hadron accelerators. The training performance of these magnets is compared with an instability factor defined by the square of the current density in the stabilizing copper divided by the surface-to-volume ratio of the strands. A good correlation is observed.
متن کاملCompensation of Magnetization Effects in Superconducting Accelerator Magnets
Magnetization effects in the coils of superconducting accelerator magnets deteriorate the field quality at injection field level. The CERN field computation program ROXIE has recently been extended to calculate the persistent currents using a semi-analytical hysteresis model for hard superconductors. The model is combined with the coupling method of finiteand boundary-elements for the calculati...
