“…In the vicinity of for instance point 10, the simulation predicts a large light yield gradient. In this region four additional measurements (16)(17)(18)(19) were carried out. The readout is triggered when both scintillators signal a MIP.…”

The High School Project on Astrophysics Research with Cosmics (HiSPARC [1]) is a large extensive air shower (EAS) array with detection stations throughout the Netherlands, United Kingdom, Denmark and Namibia. HiSPARC is a collaboration of universities, scientific institutes and high schools. The majority of detection stations is hosted by high schools. A HiSPARC station consists of two or four scintillators placed inside roof boxes on top of a building. The measured response of a detector to single incoming muons agrees well with GEANT4 [2] simulations. The response of a station to EASs agrees with simulations as well. A four-scintillator station was integrated in the KASCADE experiment [3] and was used to determine the accuracy of the shower direction reconstruction. Using simulations, the trigger efficiency of a station to detect a shower as function of both distance to the shower core and zenith angle was determined. The HiSPARC experiment is taking data since 2003. The number of stations (∼140 in 2019) still increases. The project demonstrates that its approach is viable for educational purposes and that scientific data can be obtained in a collaboration with high school students and teachers.

“…The study of the local cosmic muon flux and its dependence on environmental and astrophysical conditions provides insight into the Forbush effect, a temporary reduction in the galactic cosmic rays flux subsequent to Solar flares accompanied by Coronal Mass Ejections. 1 Anisotropies in the cosmic ray intensity induced by large scale or local magnetic field features, or by the Compton-Getting effect, have been reported but more extensive observations are needed for a quantitative understanding of this effect. Finally, the search for long distance correlations in secondary muons produced by extreme energy events, distributed over distances up to 1200 km and detected by different detectors of the EEE network is a hot topic, since it could point out a complete new feature in cosmic ray physics and be of striking importance for multi-messenger astronomy.…”

This paper describes the simulation framework of the extreme energy events (EEE) experiment. EEE is a network of cosmic muon trackers, each made of three multi-gap resistive plate chambers (MRPC), able to precisely measure the absolute muon crossing time and the muon integrated angular flux at the ground level. The response of a single MRPC and the combination of three chambers have been implemented in a GEANT4-based framework (GEMC) to study the telescope response. The detector geometry, as well as details about the surrounding materials and the location of the telescopes have been included in the simulations in order to realistically reproduce the experimental set-up of each telescope. A model based on the latest parametrization of the cosmic muon flux has been used to generate single muon events. After validating the framework by comparing simulations to selected EEE telescope data, it has been used to determine detector parameters not accessible by analysing experimental data only, such as detection efficiency, angular and spatial resolution.

The network of MRPC (Multi-gap Resistive Plate Chambers) telescopes of the Extreme Energy Events experiment (EEE) was designed to study very high energy cosmic rays through detection of secondary cosmic muons in the hadronic shower. To better understand and predict the behavior of such events, a GEANT4-based simulation framework that well reproduces the response of individual telescopes was built. Simulations are crucial to better understand the detectors performance in current setup and how these are affected by the specific installations. This is the first step towards a full simulation framework that includes a realistic generation, now limited to muons, of secondary particles and propagation through the atmosphere of the shower produced by primary rays. The current framework can be used to characterize and optimize the array of EEE telescopes, simulating not only the single detectors but also telescope's clusters, providing insight in extreme energy and rare events. In this contribution, the EEE simulation framework and future plans will be presented.
