“…A multi-detection system incorporating voltage taps, pickup coils, magnetic probes, fiber optics, and acoustic sensors is foreseen [14][15][16][17][18]. During cold testing a fast data acquisition system featuring a field-programmable gate array (FPGA) [19] will be used to simultaneously acquire signals to compare the performance of the different detection methods.…”

Future high-energy accelerators will need very high magnetic fields in the range of 20 T. The EuCARD-2 work-package-10 is a collaborative push to take HTS materials into an accelerator quality demonstrator magnet. The demonstrator will produce 5 T standalone and between 17 T and 20 T, when inserted into the 100 mm aperture of Fresca-2 high field out-sert magnet. The HTS magnet will demonstrate the field strength and field quality that can be achieved. An effective quench detection and protection system will have to be developed to operate with the HTS superconducting materials. This paper presents a ReBCO magnet design using multi strand Roebel cable that develops a stand-alone field of 5 T in a 40 mm clear aperture and discusses the challenges associated with good field quality using this type of material. A selection of magnet designs is presented as result of a first phase of development.Presented at: ASC 2014, 10-15 August, Charlotte, USA Geneva, Switzerland February 2015 Abstract -Future high-energy accelerators will need very high magnetic fields in the range of 20 T.

“…Details of the test (HD3b) were presented in [23]. The magnet exhibited a long training behavior, with ∼ 80 training quenches completed towards reaching a "plateau" in the quench current at ~ 87% of the short sample limit at 4.3 K. The summary of training quenches is shown in Fig.…”

“…Acoustic emission measurements were conducted during selected current ramps at 10-100 kSa/s acquisition rates in continuous mode as well as at 1 MSa/s in triggered mode for a 2 sec interval centered at every quench event. Quench localization using 1 MSa/s data and details of a typical AE quench precursor in HD3 was earlier presented in [23].…”

“…In block-type coils, these regions comprise most coil turns, as will be evident observing the configurations proposed in this section. The selected case is the high-field dipole magnet developed at the Lawrence Berkeley National Laboratory [135][136][137][138][139][140][141][142][143], whose geometry and magnetic-field map are shown in figures 3.13a-b. The three analyzed CLIQ configurations, presented in table 3.6, follow the same concept introduced for the two-layer cos-θ dipole geometry in section 3.3.2.…”
