In-situ, low dose rate, total ionising dose test of the cooling performance of a thermoelectric module
This work presents and discusses the design and fully automated total ionising dose test of a thermoelectric cooling module. The goal was to develop a reliable test method which can be used to measure potential total ionising dose induced degradation of the cooling performance and demonstrate this method in a long term, low dose rate experiment. Details of the tested hardware and fully automated test system are published in this work, including preliminary test results and lessons learned.
A Method for In-Situ, Total Ionising Dose Measurement of Temperature Coefficients of Semiconductor Device Parameters
This work presents and discusses a test method developed to allow the measurement of total ionising dose induced changes in temperature effects on electronic devices for space and nuclear applications. Two demonstration experiments testing commercial PMOS transistors were performed, using different methods of I-V curve measurement. The temperature of the devices during irradiation was controlled precisely using a commercial thermoelectric cooler. A programmable temperature controller combining digital and analogue control techniques was developed for this project. The experimental results allow better insight into the field of temperature sensitivity of PMOS devices.
Concept design of solar cell satellite dish
Solar panels are devices that consist of solar cells that convert light into electricity. They are called solar on the Sun or “sol” because the Sun is the strongest light source that can be utilized. Solar panels are often called photovoltaic cells, photovoltaic can be interpreted as “light-electricity”. Solar cells or PV cells depend on the photovoltaic effect to absorb the Sun’s energy and cause currents to flow between two opposing charged layers. The purpose of this study is to analyze the satellite dish using solar panels, so this tool is a signal search tool that uses solar energy to run to carry out its functions. As we know that many places or areas that are still often experiencing power outages so that it can hamper and interfere with community activities. Therefore, this research wants to facilitate the public, especially the current generation who need electricity every day so that when there is a power outage, the satellite dish will utilize solar energy as its main source. This research uses a satellite dish as an intermediary to produce electrical energy with the help of solar energy and is collected into a high-voltage battery in the form of electricity, so that it becomes a source of electricity.
