Question Anomalous number of hits 

Forum: Hits, Digitization and Pileup
Date: 26 Nov, 2009
From: Rohin <Rohin>


I am simulating mu- decays in an Aluminium stopper. I have a cylindrical Sensitive detector read out around the stopper. The read out is achieved through ReadOut geometry with a pixel size of 50um X 50um X 50um. (This is adapted from N04 Calorimeter readout).

When i simulate the the mu- decay events, I see more than one hits in a given pixel.(I make sure in my Sensitive Detector that there is a finite energy deposition in the volume to count it as a valid hit). My range cuts are set to 1um, since the secondary photons and electrons are a a major background for the experiment in this set up. However when I increase the range cuts to 1km, things are back to normal as what I expect.

Is this because of the number of steps happening in that particular region of volume. Could you suggest me a solution

Thank you
