Particle identification in solid-state detectors by exploiting pulse shape information

Trends in particle and nuclei identification techniques in nuclear physics experiments

“…The PSA in Si detector has been studied and developed during the last thirty years [162][163][164][165][166]. In these detectors, the different shapes of the signals associated with different ions, being equal their energy, are due to the variation with Z , A and E of the penetration depth and of the ionization density profile along the particle track, which in turn affect the plasma erosion time [167,168] and the collection time of the electron-hole pairs.…”

Nuclear fragment identification with ΔE-E telescopes exploiting silicon carbide detectors

“…those that cannot be identified with the ∆E-E technique) are considered. In fact, different nuclear fragments having the same kinetic energy have a different energy deposition profile as a function of the penetration depth, thus producing different charge collection times and, consequently, different pulse shapes [17][18][19][20].…”

A new method of charged particle identification based on frequency spectrum analysis

“…First the value at the specified time of the current pulse was used to identify charged particles and then the rise time of the pulse was applied in the discrimination of the proton and the alpha particles [9]. During the 1990s, G. Pausch et al were very active in the charged particle identification field, first introducing the charge balance parameter method and the charge integration method that have been widely used in n/γ discrimination into PSA [7,[10][11][12][13]. Moreover, they built a semi-empirical model to simulate the current pulse in silicon detectors for heavy ions [11].…”
