Electronics\, in general\, experience a high mortality rat e in the first few months of their use - this is especially true for parti cle physics instrumentation\, where electronic components are subjected to high temperatures\, constant loads\, and radiation. This environment nece ssitates the development of a process to test the performance and reliabil ity of the electronics to mitigate the risk of early-life failures. A burn -in station is a sophisticated testing station which emulates the high-str ess environment the electronics would experience\, in order to artificiall y age them\; data can be collected on the input and output currents and vo ltages and temperatures\, which can be graphed to find behaviour trends. T he test station\, and the data collected from running it\, can then be use d for reliability studies on the instrumentation and to create a predictiv e model as a preemptive warning system to alert technicians in advance if a component is likely to fail.\n\nhttps://indico.tlabs.ac.za/event/112/con tributions/3108/ LOCATION: Meeting Room 2.44 - 2.46 URL:https://indico.tlabs.ac.za/event/112/contributions/3108/ END:VEVENT BEGIN:VEVENT SUMMARY:SpecMAT\, the active target for nuclear transfer reactions studies at ISOLDE\, CERN DTSTART;VALUE=DATE-TIME:20230908T102000Z DTEND;VALUE=DATE-TIME:20230908T104000Z DTSTAMP;VALUE=DATE-TIME:20260719T092310Z UID:indico-contribution-540-3117@indico.tlabs.ac.za DESCRIPTION:Speakers: Oleksii Poleshchuk (KU Leuven\, Instituut voor Kern- en Stralingsfysica\, Celestijnenlaan 200d\, 3001 Leuven\, Belgium)\nSpecM AT is an active target developed for studying the shell evolution in exoti c isotopes and observing the fundamental aspects of the nuclear structure far from stability via transfer reactions carried in inverse kinematics. T he active target\, which is a novel modification of a time projection cham ber\, can acquire three-dimensional tracks of light reaction products and work in coincidence with the scintillation array sensitive to gamma-rays e mitted by the heavy reaction products. The SpecMAT is currently at its fin al developmental stage undergoing characterisation measurements at ISOLDE\ , CERN. During the most recent characterisation\, SpecMAT was installed in the ISOLDE Solenoidal Spectrometer\, which generated a magnetic field of 2.5 T. This characterisation was performed offline using a standard alpha source. In this measurement spiral tracks of alpha particles were successf ully observed in the time projection chamber of the detector. Gamma rays e mitted in the decay chain of 241Am were detected in coincidence with the p article tracks by the scintillation array. With this characterisation\, we demonstrated that all detector components could operate in the strong mag netic field and are ready for future online experiments.\nIn this talk\, r ecent Geant4 simulations of transfer reactions that can be studied with Sp ecMAT also will be presented. Using the newly developed simulation toolkit \, SpecMATscint\, we demonstrated the feasibility of studying the shell ev olution in the chain of neutron-rich copper isotopes via a (d\,3He) transf er reaction.\n\nhttps://indico.tlabs.ac.za/event/112/contributions/3117/ LOCATION: Meeting Room 2.44 - 2.46 URL:https://indico.tlabs.ac.za/event/112/contributions/3117/ END:VEVENT BEGIN:VEVENT SUMMARY:Scintillation Detector for Muon Imaging System DTSTART;VALUE=DATE-TIME:20230908T100000Z DTEND;VALUE=DATE-TIME:20230908T102000Z DTSTAMP;VALUE=DATE-TIME:20260719T092310Z UID:indico-contribution-540-2765@indico.tlabs.ac.za DESCRIPTION:Speakers: Zheng Liang (University of Science and Technology of China)\nMuon scattering tomography has a broad application prospects in h omeland security\, nuclear reactor and waste imaging\, etc. Scintillation detector is a very competitive solution due to its stability and robustnes s in harsh environment. However\, it's a challenge to develop such detecto rs with both high spatial resolution and large detection area\, especially with a limited budget. \n\nWe have built 15cm$\\times$15cm$\\times$1cm pr ototype detectors with 1cm pitch\, composed of scintillators with groove c urved on surface\, wavelength shift(WLS) fibers and SiPMs. Detectors adopt quadrangular prism\, triangular prism and slab structure respectively. Re sults show that 1-dimensional spatial resolution of these detectors are 3. 3 mm\, 1.7mm\, 6.4mm respectively\, proving that triangular prism structur e can improve resolution significantly.\n\nA GEANT4 program has been devel oped to simulate the detector's reaction to incident muons\, and to correc t systematic deviation of the detector. Simulations give an uncorrected re solution of triangular detector $\\sigma=1.5$mm\, which is close to exper imental result. After precise correction\, the spatial resolution can reac h up to 1mm within the limited 1cm pitch.\n\n\nLarge detection area is nec essary for muon imaging in several situations\, thus a detector with 45cm$ \\times$45cm area is under construction. The upgraded detector adopts a ne w layout and electronic system that designed for reducing readout channels .\n\nTwo WLS fibers are placed in one prism slat to reduce false trigger o f SiPM\, meanwhile\, four fibers from different slats make up a cluster an d are connected with a 3mm$\\times$3mm SiPM so that signals can be encoded and read out by fewer channels. Except from the electrical considerations \, the new layout also improve photon collection efficiency and spatial re solution. Several properties of the detector will be tested and reported\, e.g. spatial resolution\, acceptance\, detection efficiency.\n\nhttps://i ndico.tlabs.ac.za/event/112/contributions/2765/ LOCATION: Meeting Room 2.44 - 2.46 URL:https://indico.tlabs.ac.za/event/112/contributions/2765/ END:VEVENT END:VCALENDAR
