The outcomes obtained in laboratory assessments, utilizing scintillator bars read by silicon photomultipliers are reported. The present strategy is the first step for designing a precision monitoring system to be placed inside a free magnetized quantity for the charge identification of low vitality crossing particles. The devised system is demonstrated ready to supply a spatial decision better than 2 mm. Scintillators, Photon Solid State detector, particle monitoring units. Among the many planned activities was the construction of a mild spectrometer seated in a 20-30 m3 magnetized air quantity, the Air Core Magnet (ACM). The entire design must be optimised for the dedication of the momentum and cost of muons in the 0.5 - 5 GeV/c vary (the mis-identification is required to be less than 3% at 0.5 GeV/c). 1.5 mm is required contained in the magnetized air volume. In this paper we report the outcomes obtained with a small array of triangular scintillator bars coupled to silicon photomultiplier (SiPM) with wavelength shifter (WLS) fibers.

This bar profile is right here demonstrated able to supply the required spatial resolution in reconstructing the position of the crossing particle by profiting of the charge-sharing between adjoining bars readout in analog mode. SiPMs are excellent candidates in replacing normal photomultipliers in many experimental conditions. Tests have been carried out with laser beam pulses and radioactive supply with a view to characterize the scintillator bar response and SiPM behaviour. Here we briefly current the noticed behaviour of the SiPM utilized in our tests regarding the principle sources of noise and the impact of temperature on its response and linearity. Several models and packaging have been considered. The main source of noise which limits the SiPM’s single photon decision is the "dark current" price. It's originated by charge carriers thermally created within the delicate volume and ItagPro current in the conduction band and due to this fact it is determined by the temperature. The dependence of the darkish current single pixel rate as a function of the temperature has been investigated using Peltier cells in order to change and keep the temperature managed.

Dark present price depends additionally on the Vwk as proven in Fig. 3. As a way to have low charges of dark current the value of Vbias has been fixed at 1.5 V giving a working voltage Vwk of 29 V. It is clear that, if essential, it can be handy to use a bias voltage regulator ItagPro which mechanically compensates for temperature variations. Not all the time the pixels of the SiPM work independently from one another. Photoelectrons (p.e.) can migrate from the hit pixel to a different circuitously fired by a photon. Optical cross-speak between pixels results in a non-Poissonian behaviour of the distribution of fired pixels. An estimate of the optical cross discuss likelihood could be obtained by the ratio double-to-single pulse charge as a perform of the temperature. The chance relies upon weakly on the temperature and ItagPro the measured degree of cross-discuss (15-16%) is appropriate with the one reported within the datasheet. SiPM response as soon as its fundamental parameters and cells configuration are given.

In the Fig. 4 it is shown the pulse height distribution of the darkish present for the SiPM under check. 0.2) mm diameter hole used to lodge a fiber to collect the light. The lateral floor of the scintillator iTagPro features strips is painted with white EJ-510 TiO2 Eljen paint. The scintillation light is collected with 1.2 mm BCF-91A WaveLength Shifter (WLS) fiber produced by the Saint-Gobain Ltd. The WLS is glued into the hole working along the bar and its ends are polished. The learn-out is carried out by the SiPM solely at one end and the other facet is mirrored with reflecting tape to maximize the sunshine assortment. The front-finish board prototype devoted to the amplification and SiPM readout has been developed by the Bologna INFN electronic group. The present from the SiPM is discharged on the low input resistance of the transimpedance amplifier; this offers small time constants, that's, fast signal rise time (utilizing the OPA 656N with a 500 MHz bandwidth we receive indicators with 20-30 ns of rise time).
