Backward Monte-Carlo applied to muon transport

We discuss a backward Monte-Carlo technique for muon transport problem, with emphasis on its application in muography. Backward Monte-Carlo allows exclusive sampling of a final state by reversing the simulation flow. In practice it can be made analogous to an adjoint Monte-Carlo, though it is more versatile for muon transport. A backward Monte-Carlo was implemented as a dedicated muon transport library: PUMAS. It is shown for case studies relevant for muography imaging that the implementations of forward and backward Monte-Carlo schemes agree to better than 1%.

RPC application in muography and specific developments

Muography is an imaging technique for large and dense structures as volcanoes or nuclear reactors using atmospheric muons. We applied this technique to the observation of the Puy de Dôme, a volcano 2 km wide close to Clermont-Ferrand, France. The detection is performed with a 1m$\times$1m$\times$1.80m telescope made of 4 layers of single gap glass-RPCs operated in avalanche mode. The 1 cm$^2$ pad readout uses the Hardroc2 ASICs. The three data taking campaigns over the last three years showed that a RPC detector can be operated in-situ with good performances. Further developments to decrease the gas and power consumption and to improve the position and timing resolution of the detector are ongoing.
