Dear Sir, I am tracking an electron in Xenon gas. I found that the change of the kinetic energy of an electron does not equate to the deposit energy (dEstep) in a tracking step. The total deposit energy does not equate to total change of kinetic energy of the electron also, as seen below in an example of tracking. Could you tell me whether it is correct and why?

Dear Sir, Thank for your considerations. I have found out the meaning of "energy deposited". It is my misunderstanding the concept to cause such a problem. The change of the kenitic energy change of an electron is the sum of kenitic energy of its secondaries and energy deposited. Thanks, Yuxin
