The chance to build a SiPM-readout muon detector (SiRO), utilizing plastic scintillators with optical fibers as sensitive quantity and iTagPro website readout by SiPM photograph-diodes, is investigated. SiRO shall be used for tracking cosmic muons based mostly on amplitude discrimination. The detector concept foresees a stack of 6 energetic layers, grouped in 3 sandwiches for figuring out the muon trajectories through three planes. The attenuation of the sunshine response along the optical fiber and throughout the channels have been tested. The measurements of the incident muons based mostly on the input amplitude discrimination indicate that this process is just not efficient and therefore not enough, iTagPro website as solely about 30% of the measured occasions could possibly be used in the reconstruction of the muon trajectories. Based on the studies introduced in this paper, the layout used for iTagPro smart tracker building the SiRO detector will be modified as nicely as the analog acquisition technique will be changed by a digital one.

On this course we goal to setup a multi-goal, cell muon tracking detector based on SiPM readout, referred to as SiRO, the SiPM ReadOut muon detector. The goal of the current paper is to analyze the likelihood to find out the muon incidence and iTagPro website their trajectories using scintillator layers readout by optical fibers considered by SiPM devices and analysing the amplitude of the events. The final concept of the SiRO detector is presented as well as exams and iTagPro website measurements with a setup of two first detection modules are described. Unirea salt mine from Slanic Prahova, Romania. The fist prototype is composed of 6 energetic layers (Fig. 1), each layer consisting of 4 detection modules. Three with 12 parallel and equidistant ditches on its surface, every ditch stuffed with optical fibers. Two adjoining optical fibers are connected to a SiPM machine to kind a channel, ItagPro so that each detection module have six channels. In Figure 2 a sketch of 1 active layer is offered.

Each group of two active layers (from high to backside), with the optical fibers positioned on perpendicular instructions, signify a sandwich, which ought to determine the position within the enter XY aircraft of the incident charged particle. Thus, as we can see in Fig. 1, six active layers with four SiRO modules every, grouped in three sandwiches, are put in coincidence to permit the reconstruction of the muon trajectory. The six energetic layers are indicated as Det1 to Det6 and contain 24 channels every, so the entire system will give info from 144 individual channels. The 24 alerts from each lively layer are used as an enter by a trigger module to create coincidences by a sure multiplicity standards so as to produce a set off sign, marking an event of curiosity. The set off sign is distributed by daisy chain alongside three modules sixty four Channel Digitizer (V1740 CAEN). These modules permit to open an acquisition window with selected pre-set off time, compensating in this fashion the required delay to supply the set off pulse.

A USB2.0 Bridge (V1718 CAEN) is used to transfer the digitized alerts to a Pc. Each channel of the digitizer has a SRMA memory, the place the event might be readout by using the PCI-VME bridge module. The events are learn sequentially and transmitted to the computer. To test the performances of the deliberate SiRO detector, ItagPro i.e. its properties, in addition to its fluctuations related to bias voltage, temperature, or the space between the interplay level and the SiPM device, two detection modules have been constructed and positioned in containers for optical screening. To interpret the sunshine signal produced at the interaction of a charged particle with the delicate quantity of the detector, devices like photomultipliers or photodiodes are used to convert the light yield into electrical output by photoelectric impact. Much like photodiodes, a Silicon Photomultiplier is a semiconductor machine, however their sensitive volume is divided into a matrix of lots of of unbiased micro-cells, iTagPro geofencing also named pixels, related in parallel. Each micro-cell is operated in Geiger mode, the output signal of the SiPM device being proportional with the variety of independent pixels triggered concurrently.
