First Simulations on GEMC

For the study of the Kaon Aerogel Cerenkov Detector in the SHMS, some simulations are being prepared using GEMC code. GEMC is a code based on the Geant4.

A first model of the detector was constructed using the standard library of the GEMC, with the standard materials and geometries. The following pictures show this first simplified model of the detector.

First model of the Aerogel Detector on GEMC

First simulation on GEMC: a single Pion passing through the aerogel detector. Its velocity is lower than the threshold velocity of the aerogel, no Cerenkov radiation was emitted.

Layers of the Aerogel Detector simulated in GEMC (not scaled). From the right to the left (in the path of the particles): honeycomb first skin (Aluminum), honeycomb inside (Air), honeycomb second skin (Aluminum), aerogel, diffusion box inside (Air) and upper plate (Aluminum).

Setting the GEMC code to work with material optical properties, a high momentum Pion was generated to pass through the aerogel. The following pictures shows the first results on these simulation. The end plate was set to absorb the photons, so it was possible to see the cone of photons generated by the Cerenkov phenomena.
