Realization and First Test Results of the EuCARD 5.4-T REBCO Dipole Magnet
/ Durante, Maria ; Borgnolutti, Franck ; Bouziat, Denis ; Fazilleau, Philippe ; Gheller, Jean-Marc ; Molinie, Frederic ; De Antoni, Philippe
Abstract:
A high-temperature critical superconductor (HTS) dipole magnet relying on 12-mm REBCO tapes was built at CEA Saclay in 2016. Magnet studies had been started in the framework of the EuCARD High Field Magnet program and continued within a collaboration agreement between CEA-Saclay and CERN. [...]

Measurement of the ratio of branching fractions $\mathcal{B}(B^0 \to D^{*-}\tau^{+}\nu_\tau)/\mathcal{B}(B^0 \to D^{*-}\mu^{+}\nu_\mu)$ with $\tau$ three-prong decays
/ Wormser, Guy (Orsay, LAL)
/LHCb
The prospects of a measurement of the branching fraction ratio $\mathcal{R}(D^*) \equiv \mathcal{B}(B^0 \to D^{*−} \tau^+ \nu_{\tau})/ \mathcal{B}(B^0 \to D^{*−} \mu^+ \nu_{\mu})$ is performed by using a data sample, corresponding to $3 \text{fb}^{−1}$ integrated luminosity, collected by LHCb at center-of-mass energies of 7 and 8 TeV during the LHC Run 1. The $\tau$ lepton is reconstructed in the hadronic decay with three charged pions. [...]

Development of a 100 kW, 12.5 kV, 22 kHz and 30 kV insulated medium frequency transformer for compact and reliable medium voltage power conversion
/ Isler, Stephane (ABB SECHERON SA, Satigny) ; Chaudhuri, Toufann (ABB SECHERON SA, Satigny) ; Aguglia, Davide (CERN) ; Bonnin, Xavier Abel (CERN)
This paper presents the critical design aspects addressed during the development of a 100 kW, 12.5 kV, 22 kHz, and 30 kV insulated medium frequency transformer used in a power converter. The transformers are used in a resonant multilevel converter topology producing HV DC voltage from a three phase 400 V AC industrial grid. [...]

The upgrade of the ALICE Inner Tracking System
/ Ravasenga, Ivan (Turin Polytechnic ; INFN, Turin)
/ALICE
In 2021, for the third run of the CERN Large Hadron Collider (LHC), Pb-Pb collisions will be performed at a centre-of-mass energy per nucleon of 5.5 TeV, with an integrated luminosity of $6 \times 10^{27}$ cm$^{-2}$ s$^{-1}$ and at an unprecedented interaction rate up to 50 kHz. To fulfil the requirements of the ALICE physics program for Run 3, the ALICE experiment at LHC is planning a major upgrade during the Long Shutdown 2 of LHC in 2019-2020. [...]
