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
conditions. The simulations were used to study instrumentation related effects in coincidence timing
and position sensitivity, such as background in time-of-flight–energy histograms. Corresponding
measurements were made and simulated results are compared with data collected using the digitizing
setup.

(Elsevier; North-Holland, 2019)Fast-timing measurements at the focal plane of a separator can suffer from poor timing resolution. This is due to the variations in time-of-flight (ToF) for photons travelling to a given detector, which arise from the ... -
