Fig. 3From: A potential space- and power-effective muon sensor module for imaging a volcanoElectrical block diagram used at the experiment. Signals from #A1 to #D12 are analyzed in the PC, where the difference between the number of #A and #C corresponds to the vertical angle (θ), and the difference between the number of #B and #C corresponds to the horizontal angle (ϕ).Back to article page
