Abstract
Fast cycled superconducting magnets (FCM's) are an option of interest for the long-term consolidation and upgrade plan of the LHC accelerator complex. In the past two years we have conducted an R&D targeted at investigating the feasibility, operational issues and economical advantage of FCM's in the range of 2 T bore field, continuously cycled at 1 Hz. In this paper we report the main results on the development of strands and cables suitable for this application, providing details on the strands tested and the cable manufacturing and performance.
Highlights
E NERGY efficient, superconducting, fast-cycled magnets (FCM’s) would be a holy grail for accelerator applications including high energy physics, nuclear physics, or hadron therapy
Parallel and complementary to on-going development at FAIR [1] and INFN [2], we have launched at CERN an R&D to explore the possibility to produce dipole fields in the range of 2 T at 1 Hz taking advantage of the superferric concept pursued for the FAIR SIS-100 accelerator
We start by describing the strands used and their measured properties, we give details on the cable manufacturing, and we report the main results of the tests performed in the FReSCa test facility at CERN [5]
Summary
E NERGY efficient, superconducting, fast-cycled magnets (FCM’s) would be a holy grail for accelerator applications including high energy physics, nuclear physics, or hadron therapy. The main feature of the magnet is the use of a cryostated coil in a warm iron yoke, which should yield overall cryogenic loss below 5 W/m of magnet [3]. This is a factor approximately 3 smaller than the present GSI SIS-100 design that we take as a benchmark [4]. We start by describing the strands used and their measured properties, we give details on the cable manufacturing, and we report the main results of the tests performed in the FReSCa test facility at CERN [5]. The objective is to provide a benchmark for the performance of the demonstration magnet
