“…To pass the geometry to Geant4 DetectorConstruction, the files are then converted into geometry description markup language (GDML) geometry description format [11]. The conversion from STL to GDML is done with cad to Geant4 converter [12]. The final geometry is split into sub-branches either by their physical location in the LHC tunnel, or by the detector subsystem.…”

The MoEDAL (the monopole and exotics detector at the LHC) experiment is located at the interaction point 8 (IP8) of the large hadron collider (LHC). It is an experiment that is dedicated to searches for exotic particles, such as magnetic monopoles and dyons. The experiment is being upgraded with scintillator detectors called as the MAPP (MoEDAL apparatus for penetrating particles). They will extend the physics reach of the experiment by providing sensitivity to millicharged and long-lived exotic particles. The MAPP detectors are planned to be installed, or are already installed in various adjacent tunnels at about 50 to 100 meters from the IP8. To study the physics reach and to support the data analysis of the detectors, we developed a detailed simulation model with Geant4. The model consists of all tunnels, accelerator components between the detectors and the IP8, and of about 100 meters thick ground layer above the tunnels for cosmic ray background studies. In addition to geometry, new physics models that describe the interactions of exotic particles, such as millicharged particles, are implemented into the model.

“…The GEANT4 tool kit in turn offers a transparent way of implementing custom physics models combined with a wealth of state-of-the-art particle propagation codes and extensive user support. Last but not least, GEANT4 offers a straightforward machinery for implementing the precise detector geometry, in particular through conversion from CAD engineering drawings [20,21,22], which is crucial for accurate comparison of simulation with experimental data. Should be noted though that the software with similar CAD import functionality has been recently developed for FLUKA as well, through the integration with DAGMC libraries [23].…”

Cosmic ray research field has entered a brave new world of precise direct measurements in the multi-TeV energy domain thanks to the success of the newest space-borne instruments. DAMPE is a satellite astroparticle detector aimed at probing cosmic ray electrons and gamma rays from few GeV to 10 TeV and cosmic ray nuclei between 10 GeV and few hundred TeV with unprecedented energy resolution. It was successfully launched in December 2015, providing, in particular, the first direct observation of a break in a cosmic ray electron plus positron spectrum around 0.9 TeV. DAMPE presents a unique opportunity of directly measuring the cosmic ray spectrum and composition close to the knee region. However, one of the most challenging limitations on the precision of such measurement arises from the simulation of hadronic interactions in the detector. In spite of the utmost thick and finely segmented calorimeter onboard DAMPE, the cosmic ray proton and nuclei energy measurements still rely significantly on the hadronic Monte Carlo simulation. In this contribution, we discuss the challenges of the hadronic Monte Carlo detector simulation for TeV-PeV particles and review the existing solutions. We also present an in-house software tool which allows connecting the high-energy hadronic event generators, used in CORSIKA and implemented in the CRMC package, to the GEANT4 tool kit. Finally, we discuss preliminary simulation results with DAMPE setup based on this tool. Comparison with the alternative FLUKA simulation is presented as well.

“…The material between the active parts will be minimized to ensure the physics performance while keeping the stability of the overall mechanics. The SSD is the key component in STK and the HERD baseline is to use the same SSD as in DAMPE [4] (Fig. 4 , (201 E Web of Conferences https://doi.org/10.1051/e onf /201920 PJ pjc 9) 209 0 18 10 9010 RICAP-40 40 panel 1).…”

The High Energy cosmic-Radiation Detection (HERD) facility will be one of the space astronomy payloads on board the future Chinese space station. The ambitious aim of HERD is the direct detection of cosmic rays towards the “knee” region (~ 1 PeV), with a detector able to measure electrons, photons and nuclei with an excellent energy resolution (1% for electrons and photons at 200 GeV and 20% for nuclei at 100 GeV - PeV), an acceptance 10 times the one of present generation missions (~ 1 m2 sr), and long life-time (> 10 years). The primary objectives of HERD are the indirect search for dark matter particles and the precise measurement of energy distribution and composition of cosmic rays from 30 GeV up to a few PeV, determining the origin of the “knee” structure of the spectrum. Furthermore, HERD will monitor the high energy gamma-ray sky from 500 MeV, observing gamma-ray bursts, active galactic nuclei, galactic microquasars, etc. HERD will be composed of a homogeneous calorimeter, surrounded by a particle tracker and a plastic scintillator detector. Two possible trackers are under study: a 5-side tracker made of silicon strip detectors and a 4-side scintillating fiber tracker with a silicon strip top tracker. The total volume of HERD will be (2.3 × 2.3 × 2.6) m3 with a weight of about 4 t. The HERD design, perspectives, expected performances in terms of energy sensitivity and acceptance will be presented in this contribution.
