Future Trends in Linacs / Degiovanni, Alberto (CERN)
High-frequency hadron-therapy linacs have been studied for the last 20 years and are now being built for dedicated proton-therapy centres. The main reason for using high-frequency linacs, in spite of the small apertures and low-duty cycle, is the fact that, for such applications, beam currents of the order of a few nA and energies of about 200 MeV are sufficient [...]

Mass-selective ion ejection from multi-reflection time-of-flight devices via a pulsed in-trap lift / Wienholtz, F (Greifswald U. ; CERN) ; Kreim, S (CERN ; Heidelberg, Max Planck Inst.) ; Rosenbusch, M (Greifswald U.) ; Schweikhard, L (Greifswald U.) ; Wolf, R N (Heidelberg, Max Planck Inst.)
A method for high-resolution mass selection is presented which makes use of a multi-reflection time-of-flight mass spectrometer with in-trap lift. The new method needs no additional gating or deflection components. [...]

Measurement of time-dependent $CP$ violation in $B^0_s \to D^\mp_s K^\pm$ decays with LHCb / Eitschberger, U (Tech. U., Dortmund (main)) /LHCb
In $B^0_s \to D^\mp_s K^\pm$ decays $CP$ violation in the interference between direct decay and decay after mixing results in a time-dependent asymmetry of the decay rates. From a measurement of this asymmetry five $CP$ observables can be determined, which are themselves sensitive to the CKM angle $\gamma$. [...]

Search for Exotic Phenomena using Events with Same Charge Dileptons + b-Jets at 13 TeV with ATLAS / Jones, Sarah L (Arizona U.) /ATLAS
A search is presented using events with $b$-jets, sizable missing transverse energy and total transverse momentum from leptons and jets ($H_T$), and at least two leptons with the same charge in the final state (three lepton final states are also considered). The Standard Model (SM) processes that produce final states of this sort are relatively rare, so the SM backgrounds for this search are low. [...]

Heavy neutrino searches and NA62 status / Lurkin, N (Birmingham U.) ; Rinella, G Aglieri ; Aliberti, R ; Ambrosino, F ; Ammendola, R ; Angelucci, B ; Antonelli, A ; Anzivino, G ; Arcidiacono, R ; Azhinenko, I et al. /NA62
The NA62 experiment at CERN SPS recorded in 2007 a large sample of $K^+ \to \mu^+ \nu_{\mu}$ decays. A peak search in the missing mass spectrum of this decay is performed. [...]

A MOdular System for Acquisition, Interface and Control (MOSAIC) of detectors and their related electronics for high energy physics experiment / De Robertis, G (INFN, Bari) ; Fanizzi, G (INFN, Bari) ; Loddo, F (INFN, Bari) ; Manzari, V (INFN, Bari) ; Rizzi, M (INFN, Bari)
In this work the MOSAIC (“MOdular System for Acquisition, Interface and Control”) board, designed for the readout and testing of the pixel modules for the silicon tracker upgrade of the ALICE (A Large Ion Collider Experiment) experiment at teh CERN LHC, is described. It is based on an Artix7 Field Programmable Gate Array device by Xilinx and is compliant with the six unit “Versa Modular Eurocard” standard (6U-VME) for easy housing in a standard VMEbus crate from which it takes only power supplies and cooling..

Advances on micro-RWELL gaseous detector / Morello, Gianfranco (Frascati) ; Bencivenni, G (Frascati) ; Benussi, L (Frascati) ; De Simone, P (Frascati) ; Felici, G (Frascati) ; Gatta, M (Frascati) ; Poli Lener, M (Frascati) ; De Oliveira, R (CERN) ; Ochi, A (Kobe U.) ; Borgonovi, L (INFN, Bologna) et al.
The R&D; on the micro-Resistive-WELL ($\mu$-RWELL) detector technology aims in developing a new scalable, compact, spark-protected, single amplification stage Micro-Pattern Gas Detectors (MPGD) for large area HEP applications as tracking and calorimeter device as well as for industrial and medical applications as X-ray and neutron imaging gas pixel detector. The novel micro- structure, exploiting several solutions and improvements achieved in the last years for MPGDs, in particular for GEMs and Micromegas, is an extremely simple detector allowing an easy engineering with consequent technological transfer toward the photolithography industry.
