Slip-stick mechanism in training the superconducting magnets in the Large Hadron Collider

Pier Paolo Granieri

Superconducting magnets can exhibit training quenches during successive powering to reaching nominal performance. The slip-stick motion of the conductors is considered to be one of the mechanisms of training. In this paper we present a simple quantitative ...

Ring magnets for magnetic beads trapping in a capillary

Hubert Girault, Anne-Laure Gassner

This paper introduces the concept of ring magnets for magnetic beads (MBs) trapping in a capillary. Such magnets enable an easy insertion of a capillary simply like a pearl on a string. With this system, high magnetic forces are obtained thanks to the prox ...

Magnetic Stationary Phases for Protein Adsorption

Anne-Laure Gassner

Magnetic beads (MB) have now proven to be a powerful tool in both research and biomedical applications. They are available in a wide range of sizes (from nm to several µm) and their surface can be modified with molecules having biological specificities and ...

Beam-Machine Interaction Studies for the Phase II LHC Collimation System

Luisella Lari

Collimation is essential in a high Energy and Intensity hadron collider with SuperConducting magnets, like the LHC at CERN. To improve the cleaning efficiency and to reduce the LHC impedance budget in stable condition and at top Energy, additional 30 Phase ...

Transient Heat Transfer Model and Stability Analysis of helium-cooled Superconducting Cables

Luca Bottura, Pier Paolo Granieri, Panagiota Xydi

The stability is a key issue to design superconducting magnets and to ensure their proper exploitation. This is the case of the imminent operation of the Large Hadron Collider (LHC) accelerator, which requires a good knowledge of the stability margin of it ...

70 kA high temperature superconductor current lead operation at 80 K

Rainer Wesche

For the superconducting magnet system of the International Thermonuclear Experimental Reactor, ITER, 60 current leads for a total current of more than 2500 kA are needed. To reduce the resultant large refrigerator load at 4.5 K, High Temperature Supercondu ...

Quench simulation in superconducting cables using optimized DRP scheme

A high order finite difference scheme is introduced to deal with thermo-hydraulic quench simulation in superconducting magnets, specifically in the case of cable-in-conduit conductors (CICC). Liquid helium flow in CICC is governed by the unsteady convectio ...

Development of a 20 kA high temperature superconductor current lead

Martin Vogel

The reduction of static heat load in superconducting magnet systems is of great importance because of reduction of refrigeration power and operational costs. The major elements that determine the heat load are the current leads. The use of high temperature ...

The hydraulic solver Flower and its validation against the QUELL experiment in SULTAN

Luca Bottura

Knowledge of the hydraulic boundary conditions is a prerequisite for accurate estimates of the quench characteristics of superconducting magnets. A set of routines (Flower) has been designed and interfaced to the code Gandalf to provide a simplified model ...

Development of Ag-sheathed Bi(2223) tapes with oriented filaments

Francesco Grilli

Ag-sheathed (Bi,Pb)2Sr2Ca2Cu3O10 tapes have been developed with a special filament configuration that can be of great interest when a magnetic field is applied to the tape at a significant angle with respect to the a–b planes of the superconductor. The fab ...
