Queclink GV300 is a compact gadget designed for ItagPro hid set up in the vehicle. There are each inner and iTagPro tracker exterior GPS antennas: in different phrases, exterior antenna is non-obligatory. The gadget is embedded with rechargeable backup battery. Three LED indicators help in the course of the installation and iTagPro support diagnostic. Queclink GV300 is just not waterproof. Due to GNSS chip from ublox and useful firmware Queclink GV300 helps: multi-system navigation (GPS and GLONASS), Assisted GPS (A-GPS) technology and iTagPro support Cell ID primarily based location. The overall sensitivity is good enough (if needed you can join an external GPS antenna). Together with adjustable monitoring modes all of these guarantee dependable and correct GPS tracking. There are number of inputs in GV300, including analog ones, which allow to connect a number of car sensors of varied varieties. To control external tools a few outputs is used. One serial interface (type RS232) lets connect, on user’s alternative, digital gas level sensor, camera, PND (Garmin protocol is supported) or iTagPro geofencing exterior CAN reader. As a GPS tracker producer Queclink is well-known for its useful devices with comprehensive firmware, and GV300 shouldn't be the exception. The firmware permits to configure a whole lot of choices (including distant control over GPRS), detect a variety of occasions, iTagPro geofencing read information from CAN bus and digital gas level sensors, use Garmin-appropriate PND, monitor driving behaviour. The firmware of Queclink GV300 might be up to date OTA (Over-the-Air). There is only one RS232 serial interface, iTagPro support which generally is a limitation if you would like to attach a number of digital gadgets, i.e. two gasoline sensors or gas sensor and digital camera. For these circumstances RS485 interface can be higher, but there is no such thing as a such an interface.

The outcomes obtained in laboratory checks, utilizing scintillator bars learn by silicon photomultipliers are reported. The current approach is the first step for designing a precision tracking system to be positioned inside a free magnetized volume for the cost identification of low energy 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 deliberate actions was the construction of a mild spectrometer seated in a 20-30 m3 magnetized air quantity, the Air Core Magnet (ACM). The whole design ought to be optimised for the determination of the momentum and charge of muons within the 0.5 - 5 GeV/c vary (the mis-identification is required to be lower than 3% at 0.5 GeV/c). 1.5 mm is required contained in the magnetized air quantity. On 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 in a position to supply the necessary spatial decision in reconstructing the position of the crossing particle by profiting of the charge-sharing between adjoining bars readout in analog mode. SiPMs are wonderful candidates in replacing commonplace photomultipliers in lots of experimental circumstances. Tests have been performed with laser beam pulses and radioactive supply in an effort to characterize the scintillator bar response and SiPM behaviour. Here we briefly current the noticed behaviour of the SiPM used in our assessments regarding the primary sources of noise and the effect of temperature on its response and linearity. Several fashions and packaging have been considered. The principle source of noise which limits the SiPM’s single photon resolution is the "dark current" rate. It's originated by cost carriers thermally created within the sensitive volume and present within the conduction band iTagPro geofencing and therefore it depends upon the temperature. The dependence of the darkish present single pixel charge as a function of the temperature has been investigated using Peltier cells in order to vary and keep the temperature managed.

Dark current fee depends additionally on the Vwk as shown in Fig. 3. In an effort to have low charges of darkish present the value of Vbias has been fixed at 1.5 V giving a working voltage Vwk of 29 V. It is evident that, if crucial, it can be handy to use a bias voltage regulator which automatically compensates for temperature variations. Not always 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-discuss between pixels leads to a non-Poissonian behaviour of the distribution of fired pixels. An estimate of the optical cross talk probability could be obtained by the ratio double-to-single pulse charge as a operate of the temperature. The chance depends weakly on the temperature and the measured degree of cross-talk (15-16%) is appropriate with the one reported within the datasheet. SiPM response once its fundamental parameters and cells configuration are given.
