The possibility to construct a SiPM-readout muon detector (SiRO), using plastic scintillators with optical fibers as sensitive volume and readout by SiPM picture-diodes, is investigated. SiRO shall be used for monitoring cosmic muons primarily based on amplitude discrimination. The detector idea foresees a stack of 6 lively layers, best bluetooth tracker grouped in three sandwiches for determining the muon trajectories by means of three planes. The attenuation of the light response along the optical fiber and throughout the channels have been examined. The measurements of the incident muons based mostly on the input amplitude discrimination point out that this process isn't environment friendly and therefore not adequate, as only about 30% of the measured events might be used within the reconstruction of the muon trajectories. Based on the studies introduced on this paper, the layout used for building the SiRO detector can be modified as properly because the analog acquisition technique shall be changed by a digital one.
In this course we aim to setup a multi-purpose, cellular muon monitoring detector based mostly on SiPM readout, referred to as SiRO, the SiPM ReadOut muon detector. The goal of the current paper is to analyze the chance to find out the muon incidence and their trajectories utilizing scintillator layers readout via optical fibers considered by SiPM devices and analysing the amplitude of the events. The final concept of the SiRO detector is introduced in addition to assessments and measurements with a setup of two first detection modules are described. Unirea salt mine from Slanic Prahova, iTagPro tracker Romania. The fist prototype is composed of 6 energetic layers (Fig. 1), every layer consisting of four detection modules. 3 with 12 parallel and equidistant ditches on its floor, each ditch stuffed with optical fibers. Two adjacent optical fibers are related to a SiPM machine to kind a channel, so that every detection module have six channels. In Figure 2 a sketch of one lively layer is presented.
Each group of two active layers (from top to bottom), ItagPro with the optical fibers positioned on perpendicular instructions, symbolize a sandwich, best bluetooth tracker which should determine the position within the input XY plane of the incident charged particle. Thus, as we can see in Fig. 1, six lively layers with four SiRO modules every, ItagPro grouped in three sandwiches, are put in coincidence to allow the reconstruction of the muon trajectory. The six lively layers are indicated as Det1 to Det6 and best bluetooth tracker include 24 channels every, so the whole system will give information from 144 particular person channels. The 24 alerts from every lively layer are used as an input by a set off module to create coincidences by a certain multiplicity criteria so as to provide a trigger signal, marking an occasion of interest. The set off signal is shipped by daisy chain along 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 necessary delay to provide the trigger pulse.
A USB2.Zero Bridge (V1718 CAEN) is used to switch the digitized signals to a Pc. Each channel of the digitizer has a SRMA reminiscence, the place the event will be readout by using the PCI-VME bridge module. The events are read sequentially and best bluetooth tracker transmitted to the computer. To test the performances of the planned SiRO detector, i.e. its properties, best bluetooth tracker in addition to its fluctuations associated to bias voltage, temperature, or the distance between the interaction point and best bluetooth tracker the SiPM system, iTagPro two detection modules have been constructed and placed in packing containers for optical screening. To interpret the sunshine signal produced on the interaction of a charged particle with the delicate volume of the detector, devices like photomultipliers or photodiodes are used to transform the sunshine yield into electrical output by means of photoelectric impact. Similar to photodiodes, ItagPro a Silicon Photomultiplier is a semiconductor device, but their sensitive quantity is divided into a matrix of lots of of impartial micro-cells, additionally named pixels, connected in parallel. Each micro-cell is operated in Geiger mode, the output signal of the SiPM machine being proportional with the number of impartial pixels triggered simultaneously.
