The possibility to construct a SiPM-readout muon detector (SiRO), utilizing plastic scintillators with optical fibers as delicate volume and readout by SiPM photo-diodes, is investigated. SiRO shall be used for monitoring cosmic muons primarily based on amplitude discrimination. The detector idea foresees a stack of 6 active layers, grouped in 3 sandwiches for iTagPro online determining the muon trajectories by way of 3 planes. The attenuation of the sunshine response along the optical fiber and across the channels have been tested. The measurements of the incident muons based on the input amplitude discrimination indicate that this process is just not efficient and therefore not sufficient, as solely about 30% of the measured events could be used within the reconstruction of the muon trajectories. Based on the research introduced in this paper, the structure used for building the SiRO detector might be modified as effectively as the analog acquisition method will probably be replaced by a digital one.

On this course we purpose to setup a multi-purpose, cellular muon monitoring detector iTagPro geofencing primarily based on SiPM readout, known as SiRO, the SiPM ReadOut muon detector. The purpose of the present paper is to analyze the chance to determine the muon incidence and their trajectories utilizing scintillator layers readout by means of optical fibers seen by SiPM units and analysing the amplitude of the occasions. The final idea of the SiRO detector is introduced in addition to exams and itagpro tracker 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), every layer consisting of four detection modules. Three with 12 parallel and equidistant ditches on its floor, iTagPro smart tracker every ditch filled with optical fibers. Two adjoining optical fibers are connected to a SiPM system to type a channel, so that each detection module have six channels. In Figure 2 a sketch of 1 energetic layer is introduced.

Each group of two energetic layers (from high to bottom), with the optical fibers positioned on perpendicular instructions, characterize a sandwich, which ought to decide the place within the enter XY airplane of the incident charged particle. Thus, as we are able to see in Fig. 1, six active layers with 4 SiRO modules every, grouped in three sandwiches, are put in coincidence to permit the reconstruction of the muon trajectory. The six lively layers are indicated as Det1 to Det6 and contain 24 channels every, so the whole system will give information from 144 particular person channels. The 24 signals from every active layer are used as an input by a set off module to create coincidences by a sure multiplicity criteria so as to supply a trigger signal, iTagPro smart tracker marking an occasion of interest. The trigger signal is shipped by daisy chain along three modules 64 Channel Digitizer (V1740 CAEN). These modules enable to open an acquisition window with selected pre-set off time, compensating in this way the mandatory delay to supply the trigger pulse.

A USB2.Zero Bridge (V1718 CAEN) is used to transfer the digitized signals to a Pc. Each channel of the digitizer has a SRMA memory, where the occasion can be readout by utilizing the PCI-VME bridge module. The events are learn sequentially and iTagPro USA transmitted to the computer. To check the performances of the planned SiRO detector, i.e. its properties, as well as its fluctuations related to bias voltage, temperature, or the space between the interplay point and the SiPM machine, two detection modules have been built and placed in containers for optical screening. To interpret the light sign produced at 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 way of photoelectric impact. Much like photodiodes, a Silicon Photomultiplier is a semiconductor gadget, but their delicate quantity is divided into a matrix of hundreds of independent micro-cells, additionally named pixels, connected in parallel. Each micro-cell is operated in Geiger mode, iTagPro online the output signal of the SiPM device being proportional with the variety of unbiased pixels triggered simultaneously.
