I have a question. Mono energy alpha particles entrance silicon detector. I can gain a spectrum. and fit the spectrum, gained a FWHM. but i didnot put the energy resolution in the material. If I put the energy resolution that could be gained from experiment into code.
runaction->eventInfo.siliconLayersEnergyDepositWithError[ptr] = runaction->eventInfo.siliconLayersEnergyDeposit[ptr] + RandGaussT::shoot( engine, 0.0, sqrt( siliconSigma[ptr]*siliconSigma[ptr] + siliconNoise*siliconNoise )
the FWHM is bigger than experiment. and the resolution of the simulation spectrum is different from the experiment. so i donnot the code is right, i donnot know how to set the energy resolution that could gained a spectrum that is similar to the spectrum of experiment.
