The chance to construct a SiPM-readout muon detector (SiRO), utilizing plastic scintillators with optical fibers as delicate quantity and iTagPro bluetooth tracker readout by SiPM photograph-diodes, is investigated. SiRO shall be used for tracking cosmic muons based on amplitude discrimination. The detector concept foresees a stack of 6 lively layers, grouped in 3 sandwiches for iTagPro reviews figuring out the muon trajectories through three planes. The attenuation of the sunshine response alongside the optical fiber and throughout the channels have been tested. The measurements of the incident muons based mostly on the enter amplitude discrimination indicate that this procedure just isn't environment friendly and due to this fact not ample, as solely about 30% of the measured events could possibly be used in the reconstruction of the muon trajectories. Based on the research introduced on this paper, the format used for building the SiRO detector will probably be changed as nicely because the analog acquisition technique will be changed by a digital one.
In this course we purpose to setup a multi-purpose, cellular muon monitoring detector based mostly on SiPM readout, ItagPro known as SiRO, the SiPM ReadOut muon detector. The purpose of the present paper is to analyze the likelihood to find out the muon incidence and iTagPro online their trajectories using scintillator iTagPro bluetooth tracker layers readout via optical fibers seen by SiPM units and iTagPro bluetooth tracker analysing the amplitude of the events. The final idea of the SiRO detector ItagPro is presented as well as tests and 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 active layers (Fig. 1), each layer consisting of 4 detection modules. 3 with 12 parallel and iTagPro bluetooth tracker equidistant ditches on its surface, each ditch filled 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 offered.
Each group of two energetic layers (from high to bottom), with the optical fibers positioned on perpendicular instructions, symbolize a sandwich, which should determine the position in the enter XY plane of the incident charged particle. Thus, as we will see in Fig. 1, six energetic layers with 4 SiRO modules every, grouped in three sandwiches, are put in coincidence to permit the reconstruction of the muon trajectory. The six active layers are indicated as Det1 to Det6 and include 24 channels every, so the whole system will give data from 144 particular person channels. The 24 alerts from every active layer are used as an enter by a set off module to create coincidences by a certain multiplicity standards so as to produce a set off sign, marking an event of interest. The trigger sign is distributed by daisy chain alongside three modules sixty four Channel Digitizer (V1740 CAEN). These modules enable to open an acquisition window with selected pre-set off time, compensating in this manner the mandatory delay to provide the trigger 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 reminiscence, where the event will be readout by using the PCI-VME bridge module. The occasions are read sequentially and transmitted to the pc. To test the performances of the planned SiRO detector, i.e. its properties, in addition to its fluctuations associated to bias voltage, temperature, or the distance between the interplay level and the SiPM gadget, two detection modules have been constructed and iTagPro features placed in packing containers for optical screening. To interpret the light signal produced at the interplay of a charged particle with the delicate quantity of the detector, gadgets like photomultipliers or photodiodes are used to convert the light yield into electrical output via photoelectric impact. Similar to photodiodes, iTagPro bluetooth tracker a Silicon Photomultiplier is a semiconductor gadget, but their sensitive quantity is divided into a matrix of a whole bunch of unbiased micro-cells, iTagPro bluetooth tracker additionally named pixels, connected in parallel. Each micro-cell is operated in Geiger mode, the output sign of the SiPM gadget being proportional with the variety of independent pixels triggered concurrently.
