simulations - Is there a mass spectrometer software that can measure the mass of a proton

I spent a lot of hours looking for mass spectrometer software (or Cathode-ray simulator) that can measure the mass of a proton or any sub atomic particle. Until now I only found software that work on isotopes, organic mixtures and other compounds.

For my school project, I need a computer simulation to measure the mass of a proton (I chose the idea not my school) so any other way of measuring a proton will not be useful to me.

Thanks in advance.
