2016 Review of Scientific Instruments  
The performance of a time-of-flight spectrometer consisting of two timing detectors and an ionization chamber energy detector has been studied using Monte Carlo simulations for the recoil creation and ion transport in the sample and detectors. The ionization chamber pulses have been calculated using Shockley-Ramo theorem and the pulse processing of a digitizing data acquisition setup has been modeled. Complete time-of-flight-energy histograms were simulated under realistic experimental

Corresponding measurements were made and simulated results are compared with data collected using the digitizing setup.
