    Description: High-T c superconducting (HTS) dipole magnets are expected to be used in the upgrade of existing particle accelerators. In the framework of EuCARD-2 project, a new dipole-generating field between 17 and 20 T is under consideration with an HTS insert providing 5 T. This has to provide a good field quality at two-thirds of 40-mm beam aperture. The HTS stacked cable is the simplest way to acquire the large current and a strong mechanical cable. A twist for a half-turn in the magnet ends partially transposes the stacked tapes and improves the current distribution. However, the twisted stacked cable exposes the ReBCO tape to magnetic fields perpendicular to their wide face, where the engineering current density J e is lower. In addition, the different strength and direction of forces cause shear stress between the tapes. The HTS twisted stacked insert is designed with a 4 × 4-mm block-coil stacked with 4-mm-wide tape. The 46-turns of stacked cable, which is almost aligned to the background field, achieve a 5 T with the required field quality. The 3-D magnet ends are designed with the racetrack and flared-ends coils. It consists of six double pancakes. One of the mechanical conditions in the coil-ends, whose block-coil is divided into four tapes, has been analyzed with the Fresca2 LTS outsert. The HTS insert is able to withstand forces on its own.

    Description: The objective of the EuCARD2 WP10 (Future Magnets) research activity is to demonstrate high-temperature superconducting magnet technology for accelerator applications by building a short demonstrator dipole with an aperture of 40 mm, operating field of 5 T, and understood field quality. One of the magnet requirements is of small inductance, for use in long magnet strings; hence, the superconducting cable must have large current-carrying capacity, in the range of 10 kA at the operating conditions of 4.2 K and 5 T. An initial down-selection of the cable material and geometry resulted in the choice of REBCO tapes assembled in a Roebel cable as the baseline layout. In this paper, we described the requirements derived from magnet design, the selection process that led to the choice of material and geometry, the reference design of the cable, and its options. Activities have started to address fundamental issues, such as tape performance and tape processing through the cable construction, and key performance parameters such as cable critical current under stress or magnetization. Here, we report the main highlights from this work.

    Description: EuCARD-2 is a project partly supported by FP7 European Commission aiming at exploring accelerator magnet technology for 20-T dipole operating field. The EuCARD-2 collaboration is liaising with similar programs for high-field magnets in the U.S. and Japan. EuCARD-2 focuses, through the work package 10 "future magnets," on the development of a 10-kA-class superconducting high-current-density cable suitable for accelerator magnets, for a 5-T stand-alone dipole of 40-mm bore and about 1-m length. After stand-alone testing, the magnet will be inserted in a large bore background dipole, 10-18 T. This paper reports on the design and development of models, which are called Feather0, wound with REBCO Roebel cable. Based on aligned block design to take advantage of the anisotropy of the REBCO tapes, Feather0 is a precursor of Feather2, which should reach the project goals in 2016. Feather0 is planned to be tested both in stand alone and as an insert mounted in the CERN Fresca facility providing 10-T background field. The progress of other designs pursued in the collaboration, one based on classical ϑ layout with Roebel cable and the other based on coil block with stacked tape cable, will be also reported.

    Description: High Tc superconducting (HTS) insert in combination with low Tc superconducting (LTS) outsert is the only possibility today to go above 16 T for future high-energy particle accelerator dipoles. These HTS inserts will feature large operating current (≥ 10 kA) and high background fields (≥ 13 T) leading to severe operating conditions. In our 46-turns HTS insert, a 4 × 4 mm twisted stacked cable composed of 20 tapes and carrying 10.4 kA is used. It is simple to manufacture and enables a partial transposition. The designed insert can generate 5 T with good field homogeneity, assuming a homogeneous current density in the cable. However, a half twist per turn applied in the magnet ends of a 15-m-long insert makes it difficult to obtain both low magnetization and uniform current distribution in the cable. Three twisted stacked cables solutions are numerically studied: noninsulated cable, insulated cable, and partially insulated cable. The simulated HTS insert is first submitted to the external field of the outsert then the current is ramped up to nominal value. The partially insulated twisted stacked cable compounds both advantages of noninsulated and insulated cables, and thus appear to be the best solution for the HTS insert.

    Description: The EuCARD2 collaboration aims at the development of a 10 kA-class superconducting, high current density cable suitable for accelerator magnets, to be tested in small coils and magnets capable to deliver 3-5 T when energized in stand-alone mode, and 15-18 T when inserted in a 12-13 T background magnet. REBCO tape, assembled in a Roebel cable, was selected as conductor. The developed REBCO tape has reached a record engineering critical current density, at 4.2 K and 18 T of 956 A/mm 2 . Roebel cable carried up to 13 kA at 20 K when tested in a small coil (FeatherM0.4). Then a first dipole magnet, wound with two low-grade Roebel cables of 25 m each, was assembled and tested. The dipole reached the short sample critical current of 6 kA generating more than 3 T central field at about 5.7 K, with indications of good current transfer among cable strands and of relatively soft transition. The construction of a costheta dipole is also discussed. Eucard2 is reaching its objective and is continuing with the H2020-ARIES program aiming at doubling the Je at 20 T to obtain 6 T as standalone and 18 T as insert in a high field facility.

    Description: In this prospective study the Glasgow Coma Scale (GCS) score was evaluated in 107 critically ill infectious disease (ID) patients admitted to the Intensive Care Unit (ICU) during a 1-year period. Patients were separated into two groups: those affected by central nervous system (CNS) infections and those affected by infections other than of the CNS. There were no apparent differences in the first ICU day GCS score values between the two groups (11 +/- 4 vs. 11 +/- 4, p = 0.5318). Univariate logistic regression analysis confirmed a significant relationship between the first ICU day GCS score and the subsequent ICU mortality in the group of patients with CNS infections (r = 0.3152, p = 0.0015) but not in the group with infections not affecting the CNS (r = 0.0919, p = 0.1106). Our preliminary results suggest that the prognostic value of the GCS score is valid only in patients with CNS infections but not in other ID patients.

    Description: An incidence study on nosocomial infections in critically ill infectious disease patients was carried out in the intensive care unit (ICU) of a university hospital for infectious diseases over a 7-year period (1 January 1990 to 31 December 1996). A total 660 patients who stayed in the ICU for over 48 h were prospectively observed. The patients were divided into two groups: one with central nervous system infections (442 patients) and the other with other severe infections (218 patients). The risk of nosocomial sepsis and pneumonia was significantly higher in patients suffering from severe central nervous system infections. The incidence of sepsis was 24.2% vs 11.4% (relative risk 1.95; 95% confidence interval 1.32–2.89); the incidence of pneumonia was 30.5% vs 14.7% (relative risk 2.09; 95% confidence interval 1.47–2.96). The incidence of urinary tract infection was 14.3% vs 13.3% (relative risk 1.07; 95% confidence interval 0.71–1.61). Density rates of nosocomial septic episodes were 21.1±37.1 vs 11.7±32.4 episodes/100 central venous-line days (P〈0.006). Nosocomial pneumonia occurred only in mechanically ventilated patients (36.9±61.2 vs 28.5±65.8 episodes per 1000 ventilatory days, P=0.012). Nosocomial urinary tract infection occurred only in patients with urinary catheters (11.6±60.7 episodes/1000 urinary catheter days vs 18.7±90.1, P=0.886). Multivariate regression analysis identified age, diagnosis of CNS infection, duration of urinary tract catheterization, the use of central venous lines and mechanical ventilation as independent risk factors of nosocomial sepsis. Duration of mechanical ventilation, use of steroids and diagnosis of CNS infection were independent risk factors of nosocomial pneumonia. A subanalysis identified tetanus patients to be at particular risk of nosocomial infections.
