First joint experiment at Vinca InstituteEF-UNINIS (Prof. Goran Ristić and student Stefan Ilić) and Tyndall National Institute (Aleksandar Jaksic) took part in the first joint experiment in the ELICSIR project. The experiment involved irradiation of commercial floating gate transistors and Tyndall stacked RADFET samples at the Institute of Nuclear Sciences Vinca, Belgrade. The results of the experiment will be used in joint research work in the project. Preparations for the upcoming project kick-off meeting, general project work plan, and planned Stefan’s visit to Tyndall were discussed.
Participation in European Researchers NightEF-UNINIS students engaged in the ELICSIR project, Stefan Ilić and Aleksandar Jevtić, participated in the European Researchers Night.
They presented a prototype of the smart Geiger-Muller counter with an Android application that can be used as a personal dosimeter. The Android app can display counts per minute (CPM), dose rate, absorbed dose and graph of radiation levels in the past 30 minutes. The application alerts the user when preset threshold dose levels are exceeded.

Luka Spahić defended the masters thesisLuka Spahić, a Masters student at EF-UNINIS and participant in the ELICSIR project, defended his master thesis Design and implementation of an electronic circuit for measuring low currents based on transimpedance amplification under the supervision of Prof. Goran Ristić. The Masters thesis was done at the Applied Physics Laboratory. Luka expresses a special gratitude to Marko Anđelković, from the partner institution IHP, for very significant help he provided during the preparation of this thesis.
This Masters thesis presents the concept of transimpedance amplification, which is designed to ensure as high as possible measurement accuracy with maximum immunity to external electromagnetic interference. As part of the thesis, the electrical circuit design method and its individual parts, simulation of the electrical circuit, as well as detailed design of the printed circuit board of the electronic circuit, are presented in detail. The measurements of the electric current were done by the realized prototype and the discussion of the measurement results is presented. A proposal for the electronic circuit application for measuring low current levels, improvement of functionality, as well as potential omissions and their elimination are given. Also, the electronic circuit enables amplification and conversion into voltage of the generated photocurrents in PIN diode during irradiation. Based on the measured current, it is possible to calculate the absorbed dose of ionizing radiation.

Stefan Ilić defended the masters thesisStefan Ilić, a Masters student at EF-UNINIS and participant in the ELICSIR project, defended his masters thesis entitled "Investigation of the possibility of using a commercial floating gate transistor as an ionizing radiation detector in high sensitivity mode", under the supervision of Prof. Goran Ristić. The research for the masters thesis was done at the Applied Physics Laboratory. Stefan is very grateful to Russell Duane and Aleksandar Jakšić from the Tyndall Institute and to Marko Anđelković from the IHP Institute for very useful help.
This masters thesis presents the use of a commercial MOS transistor with a floating gate, the so-called EPAD (Electrically Programmable Analog Device), for ionizing radiation detection in a special high-sensitivity mode (HIGHSENS). The idea is to design a linear sensor with a constant value of sensitivity to ionizing radiation. The experiment contained two variants of the high-sensitivity regime: with zero and positive bias, where zero bias gives higher sensitivity. The results show a significantly higher sensitivity of EPAD in the mode of high sensitivity and zero bias during irradiation than without such mode of operation. Also, all EPADs in the high-sensitivity mode show a linear dose dependence. The problem exists in the repeatability of the experiment, it is assumed that the cause is the tunnel oxide through which the floating gate is charged with the electrons, which does not have a satisfactory quality for this kind of work. Also, the operation of the system is quite complex and requires extensive calibration of the software.
Laza Kostić defended the masters thesisLaza Kostić, a Masters student at EF-UNINIS and participant in the ELICSIR project, defended his masters thesis entitled Self-sustaining, low-power embedded system for measuring the absorbed dose of ionizing radiation, under the supervision of Prof. Goran Ristić. The thesis was done at the Applied Physics Laboratory.
As the possibilities of nuclear energy are tested for the task of a better future here on Earth and elsewhere in space, the need for measuring nuclear energy arises. The way this can be done is by using sensors for ionizing radiation. These sensors normally generate an electrical current or voltage potential on their output, in accordance to the ionizing radiation they absorb. One application of this kind of sensor is in a system for measuring the absorbed dose of ionizing radiation. This masters thesis presents the flow and procedures of design and realization of a prototype system for this purpose, that uses sensors for sensing doses of absorbed ionizing radiation, a GPS module to gather information about its location, and a GSM module to send all the information to a base station. The system is powered by a lithium battery, charged by a solar cell via a lithium battery charger circuit. The total power consumption of the system is reduced by using a power management circuit. The system as a whole is very compact and modular, hence it is suitable for multiple use cases and conditions.
