Comparison between CLYC-6 and 3He for thermal neutron detection / Ferrulli, Francesca (CERN) ; Silari, Marco (CERN) ; Zorloni, Gabriele (CERN)
A Cs$_2$LiYCl$_6$:Ce crystal, enriched in $^6$Li to > 95% (CLYC-6), was investigated for thermal neutron detection: it was characterised in terms of intrinsic efficiency and γ-ray discrimination capability and compared with a $^3$He counter (partial $^3$He pressure 2.3 atm). The intrinsic efficiency was determined by irradiating the detectors with thermal neutrons. [...]

Eurados Rem-counter Intercomparison at Maastro Proton Therapy Centre: Comparison With Literature Data / Zorloni, Gabriele (CERN) ; Bosmans, Geert (Maastricht U.) ; Brall, Thomas (HZDR, Dresden) ; Caresana, Marco (INFN, Milan ; Milan U.) ; De Saint-Hubert, Marijke (SCK-CEN, Mol) ; Domingo, Carles (Barcelona, IFAE ; Barcelona, Autonoma U.) ; Ferrante, Christian (INFN, Milan ; Milan U.) ; Ferrulli, Francesca (CERN ; U. Caen (main)) ; Kopec, Renata (Cracow, INP) ; Leidner, Johannes (CERN) et al.
The Maastro Proton Therapy Centre is the first European facility housing the Mevion S250i Hyperscan synchrocyclotron. The proximity of the accelerator to the patient, the presence of an active pencil beam delivery system downstream of a passive energy degrader and the pulsed structure of the beam make the Mevion stray neutron field unique amongst proton therapy facilities. [...]

Analysis and comparison of the Core-to-Valence Luminescence mechanism in a large CLYC crystal under neutron and γ-ray irradiation through optical filtering selection of the scintillation light / Ferrulli, F (U. Caen (main) ; CERN) ; Caresana, M (Milan, Polytech.) ; Cova, F (Milan Bicocca U.) ; Gundacker, S (CERN) ; Kratochwil, N (CERN ; Vienna U.) ; Pots, R (CERN) ; Silari, M (CERN) ; Vedda, A (Milan Bicocca U.) ; Veronese, I (Milan U. ; INFN, Milan) ; Zorloni, G (CERN ; Milan, Polytech.)
$^7$Li enriched Cs$_2$LiYCl$_6$:Ce$^{3+}$ (CLYC) is a promising inorganic scintillator for real-time γ-ray and fast neutron spectrometry. The neutron/γ-ray discrimination is usually accomplished exploiting the different quenching effects of high Linear Energy Transfer (LET) particles on different scintillation mechanisms, usually by means of the time analysis of the pulse shape.

Investigation of CLYC-6 for thermal neutron detection and CLYC-7 for fast neutron spectrometry / Ferrulli, Francesca (Caen U. ; CERN) ; Labalme, Marc (Caen U.) ; Silari, Marco (CERN)
Highly enriched  6Li and  7Li Cs2LiYCl 6 (CLYC) scintillators were investigated in view of their application as thermal neutron counter (CLYC-6) and as fast neutron spectrometer (CLYC-7) in the recently developed B-RAD radiation survey metre, an instrument designed to work in regions of high magnetic fields, currently equipped with a probe for photon dose rate measurements and γ-spectrometry. Both crystals were irradiated with a 2.5 MeV mono-energetic neutron beam from a Deuterium–Deuterium (D–D) generator and characterised in terms of neutron/γ-ray (n/γ) discrimination capability by the Pulse Shape Discrimination (PSD) method, energy resolution and quenching factor.

Impact of the newly proposed ICRU/ICRP quantities on neutron calibration fields and extended range neutron rem-counters / Pozzi, Fabio (CERN) ; Ferrarini, Michele (CNAO, Milan) ; Ferrulli, Francesca (CERN ; Milan, Polytech.) ; Silari, Marco (CERN)
In July 2017, the International Commission on Radiation Units and Measurements (ICRU) and the International Commission on Radiological Protection (ICRP) proposed the introduction of new operational quantities for external radiation exposure, with the aim of improving coherence between protection quantities and operational quantities within the system of radiological protection. A change in operational quantities will impact both instrumentation and reference radiation fields used for their calibration. [...]

A thermal neutron source for the CERN radiation Calibration Laboratory / Ferrulli, Francesca (U. Caen (main) ; CERN) ; Silari, Marco (CERN) ; Thomsen, Frederik (CERN ; Aarhus U. (main)) ; Zorloni, Gabriele
This work presents the design, construction and experimental characterisation of a lightweight and low-cost thermal neutron assembly, to be used with the existing Am–Be source irradiator of CERN radiation Calibration Laboratory (Cal Lab). The assembly consists of a cylindrical moderator (18 cm diameter, 25.5 cm height and 5.5 kg weight) and an optional reflector box (5 cm thick walls, 20 kg weight) [...]

Characterization of stilbene and EJ-276 scintillators coupled with a large area SiPM array for a fast neutron dose rate detector / Ferrulli, F. (Caen U. ; CERN) ; Dinar, N. (CERN) ; Gallego Manzano, L. (CERN) ; Labalme, M. (Caen U.) ; Silari, M. (CERN)
A 1-inch stilbene and EJ-276 (plastic) organic scintillators were characterized in view of their use in a portable survey meter for fast neutron detection and dose rate measurements in radiation protection. They were coupled with a large area Silicon Photomultiplier (SiPM) array and characterized in terms of neutron/$\gamma$–ray (n/$\gamma$) discrimination capability, count rate linearity, count rate saturation effects, temperature stability and neutron detection efficiency.
