Towards TeV-scale electron-positron collisions: the Compact Linear Collider (CLIC) / Doebert, Steffen (CERN) ; Sicking, Eva (CERN)
The Compact Linear Collider (CLIC), a future electron-positron collider at the energy frontier, has the potential to change our understanding of the universe. Proposed to follow the Large Hardron Collider (LHC) programme at CERN, it is conceived for precision measurements as well as for searches for new phenomena..

Enhancing Light Extraction of Inorganic Scintillators Using Photonic Crystals / Salomoni, Matteo (Milan Bicocca U. ; CERN) ; Pots, Rosalinde (CERN ; RWTH Aachen U.) ; Auffray, Etiennette (CERN) ; Lecoq, Paul (CERN)
Inorganic scintillators are commonly used as sensors for ionizing radiation detectors in a variety of applications, ranging from particle and nuclear physics detectors, medical imaging, nuclear installations radiation control, homeland security, well oil logging and a number of industrial non-destructive investigations. For all these applications, the scintillation light produced by the energy deposited in the scintillator allows the determination of the position, the energy and the time of the event. [...]

Destruction of the cosmic γ-ray emitter $^{26}$Al in massive stars: Study of the key $^{26}$Al$(n,\alpha)$ reaction / n_TOF Collaboration
Neutron destruction reactions of the cosmic $\gamma$-ray emitter $^{26}$Al are of importance to determine the amount of $^{26}$Al ejected into our galaxy by supernova explosions and for 26 Al production in asymptotic giant branch stars. We performed a new measurement of the $^{26}$Al$(n, \alpha)$ reaction up to 160-keV neutron energy at the neutron time-of-flight facilities n_TOF at CERN and GELINA at EC-JRC. [...]

Multichannel Approach for Arrayed Waveguide Grating-Based FBG Interrogation Systems / Romano Marrazzo, Vincenzo  (Naples U.) ; Fienga, Francesco (Naples U. ; CERN) ; Riccio, Michele (Naples U.) ; Irace, Andrea (Naples U.) ; Breglio, Giovanni (Naples U. ; CERN)
In this manuscript, an optically passive fiber Bragg grating (FBG) interrogation system able to perform high-frequency measurement is proposed. The idea is mainly based on the use of an arrayed waveguide grating (AWG) device which is used to discriminate the fiber optic sensor (FOS) wavelength encoded response under test in function of its output channels.

A roadmap for sole Cherenkov radiators with SiPMs in TOF-PET / Kratochwil, Nicolaus (CERN ; TU Vienna) ; Gundacker, Stefan (CERN ; Aachen, Tech. Hochsch.) ; Auffray, Etiennette (CERN)
Time of flight positron emission tomography can strongly benefit from a very accurate time estimator given by Cherenkov radiation, which is produced upon a 511 keV positron–electron annihilation gamma interaction in heavy inorganic scintillators. While time resolution in the order of 30 ps full width at half maximum (FWHM) has been reported using MCP-PMTs and black painted Cherenkov radiators, such solutions have several disadvantages, like high cost and low detection efficiency of nowadays available MCP-PMTs.

Brazing of Mo to Glidcop Dispersion Strengthened Copper for Accelerating Structures / Casalegno, Valentina (Polytech. Turin) ; Perero, Sergio (Polytech. Turin) ; Ferraris, Monica (Polytech. Turin) ; Taborelli, Mauro (CERN) ; Izquierdo, Gonzalo Arnau (CERN) ; Sgobba, Stefano (CERN) ; Salvo, Milena (Polytech. Turin)
Alumina dispersion-strengthened copper, Glidcop, is used widely in high-heat-load ultra-high-vacuum components for synchrotron light sources (absorbers), accelerator components (beam intercepting devices), and in nuclear power plants. Glidcop has similar thermal and electrical properties to oxygen free electrical (OFE) copper, but has superior mechanical properties, thus making it a feasible structural material; its yield and ultimate tensile strength are equivalent to those of mild-carbon steel.

Accel. Sci. Tech. ; Liverpool U.)
Knowledge of the beam properties in proton therapy through beam monitoring is essential, ensuring an effective dose delivery to the patient. In clinical practice, currently used interceptive ionisation chambers require daily calibration and suffer from a slow response time. [...]

Development and characterization of a large area silicon pad array for an electromagnetic calorimeter / Mukhopadhyay, S (Bhabha Atomic Res. Ctr. ; HBNI, Mumbai) ; Chandratre, V B (Bhabha Atomic Res. Ctr. ; HBNI, Mumbai) ; Muhuri, S (Calcutta, VECC ; HBNI, Mumbai) ; Singaraju, R N (Calcutta, VECC) ; Saini, J (Calcutta, VECC) ; Nayak, T K (Calcutta, VECC ; Bhubaneswar, NISER ; CERN)
We present the research and development work of the first version of a 6×6 array of silicon pad detectors, carried out in India, for the proposed forward calorimeter (FOCAL) as part of the ALICE collaboration upgrade program at CERN. The primary motivation is to develop a large area silicon pad array realizing the challenging requirements of high-energy physics experiments such as low leakage current, high breakdown voltage and evaluate its performance as an active layer in the prototype silicon tungsten (Si-W) electromagnetic (EM) calorimeter.

The neutron-deficient $^{115}$Cs was produced at ISOLDE, CERN by spallation reaction using 1.4 GeV proton on LaC2 target. The exotic decay modes were studied by using a charged particle array (DSSD and pad detectors) and a γ-detector array (four Clovers) at the ISOLDE decay station (IDS). [...]
