Development of a Readout System for RadMON Sensors on Arduino YUN microcontroller

CERN develops particle accelerators. As a side effect of running these accelerators, a radiation field is usually created on devices that are operated next to the locations wher particles collide. Due to the negative effects that radiation has on the devices, it is crucial to measure it properly. As a part of this radiation detection task, the EP-DT-DD group works on the de- velopment of new techniques to monitor residual radiation such detectors that are both accurate and cheap. Specifically, the group works on the detection of radiation through silicon-based devices. The RadMON sensor, is one of these developments. It is a small and low-cost printed circuit board (PCB) mounting different combinations (tailored to specific measurement needs) of radFET and PiN diode dosimeters. Radiation is measured by monitoring the variations of conductivity of these devices. The readout of this sensor, is carried out by an Arduino YUN micro-controller plugged to a board and the system is called ReadMON. It provides the possibility to read the RadMON sensors by means of an Internet connectivity which permits the remote monitoring of the sensors. Up to now, the measured data were extracted by means of a LabView interface. However, this only allowed to obtain measurements but did not offer a dedicated display for the radiation data, and it and was not ready to be a production system. The objective of this project was to create a WebServer hosted on the Arduino YUN micro-controller, that allowed to manage the sensors on the board with flexibility, to configure the parameters on the system, to visualize the data in a collective manner through graphs that allows a proper display and an interpretation of them, and to store the data on a database also hosted by the Arduino YUN micro-controller. In this document, we first describe the set of features that are present on the system. Later, we expose the software installation process a user-manual way. Next, we describe the details of the development of the different components of the system, trying to facilitate the maintenance of the former. Finally, we conclude with the future work to be done on this system and the conclusions of the project.
