Hi, Iam working with a High purity Germanium detector and have an issue with the dead time. I let the detector do a background measurement over the weekend, about 55h. When I checked the measurement 60h had passed and the measurement was not finished due to dead time about 20%. At the start of the measurement (up to 3h) there was no dead time so this must have appeared later on. Real time = elapsed time Live time = including dead time and if dead time >0, then real time > live time. My question is, if at time 0 both real and live time are equal, but at later time, real time >> live time, is there a way to interpolate ( I have a set of measurement points) back to where this dead time possibly appeared, like intersection with x or y? Or have I misunderstood the concept of dead time in a detector. If this topic is in the wrong part of the forum, please redirect me. Thank you very much!
