Das MuonPi Cosmic Detector Project
Das MuonPi Projekt ist ein auf RaspberryPi basierendes System, das einen kostengünstigen Plastikszintillator + SiPM-Fotosensor verwendet, um Myonen aus kosmischen Luftschauern zu detektieren. Das System hat eine Zeitauflösung von einigen zehn Nanosekunden, unter Verwendung der "timemark"-Funktion des u-blox NEO-M8N GNSS Modules von u-blox.

- Extrem starke kosmische Strahlung regnet jeden Tag auf uns herab. Niemand weiß, wo genau sie herkommt. Aber mit groß angelegten Experimenten wollen Wissenschaftler auf der ganzen Wetl das herausfinden. Vox Jul 25, 2019

Die Hardware
SiPM PCB
Der SiPM Photodetektor, der das schwache Licht, das im Inneren des Szintillationsdetektor erzeugt wird, detektiert, ist auf einer kleinen SiPM-Platine montiert. Das flexible Design ermöglicht die Realisierung von verschiedenen Anzahlen und Auslesekonfigurationen der SiPMs.
Vorverstärker (Preamplifier)
Der Vorverstärker befindet sich in unmittelbarer Nähe der SiPM-Photodetektorplatine und verstärkt die schwachen Signale zur Übertragung auf die MuonPi-Platine, wo sie weiter verarbeitet und ausgewertet werden.
Das MuonPi-Board
Die Hauptsignalverarbeitung, Spannungserzeugung und Parameterüberwachung, sowie Parametereinstellung, erfolgt auf dem aufsteckbaren MuonPi-Board von Raspberry Pi.
The main signal processing, voltage generation and parameter monitoring and adjustment is done on the Raspberry Pi plug-on MuonPi Board. The board's design is open source hardware and exhibits only commercially available off-the-shelf components which can be obtained from several distributors. With some soldering experience, the MuonPi HAT can be assembled utilizing a standard soldering equipment. A how-to guide and useful hints are available in the Assembly Guide.
The Software
The MuonPi software collection is entirely open source and available on github It consists of several components:
- muondetector-daemon The main control program running as a background system service on the RPi. The daemon configures, controls and supervises the components on the MuonPi HAT board, handles the comunication to the u-Blox chip and to the outside world via MQTT link and direct access socket, monitors system parameters, such as temperature, voltages, curent, rates etc., performs statistics collections, calculations and logging and much more. The daemon can be installed through the standard system software management tools (such as apt) from our package repository or compiled from the github source and is everything which is needed to operate a MuonPi detector.
- muondetector-gui A graphical user interface (GUI) program which can be launched on any computer in the same network as the MuonPi detector in order to monitor and adjust all operation parameters of the detector, if required. The GUI is available for download as binary package for several platforms (Raspbian, Ubuntu, Windows) or can be compiled from the current github master branch.
- muondetector-login A small command line helper tool to initially set up the MQTT telemetry link. The program will ask for the supplied MQTT credentials and stores them locally in encrypted form for continuous use.
- muondetector-cluster Allows the operation of a multi-detector cluster as an entity. The program is the cluster head or interface towards the server, searches for coincidences within the cluster and sends the combined coincidence events instead of the single event telegrams to the server. This tool is in development phase with more information about it's utilization to come in near future.
Setup and Operation of the Detector
Here you find a collection of HOW-TOs useful to set-up and operate a detector:
- Detector Surveillance through a Telegram Bot
The completed setup is fairly insensitive to the location where it will operate. Basic requirement is a good GPS signal, low humidity and obviously power and network connectivity. A stable temperature for the scintillator and preamp is desirable, as it affects the noise level of the setup. Muons will penetrate several meters of granite rock, so placing the detector in the basement leaves the muon measurements unaffected. However due to radon collection in basement rooms and potassium decay a slightly higher natural radioactive background can be observed.
In case there are problems with the set-up or operation of the detector, have a look in the Troubleshooting section.
