The impact ionization process is used in modern cosmic dust detectors like the Galileo Dust Detector[2] and dust analyzers Cassini CDA,[3] Stardust CIDA and the Surface Dust Analyser[4] for the identification of dust impacts and the compositional analysis of cosmic dust particles.
In some sense, impact ionization is the reverse process to
Avalanche photodiodes (APD) are used in optical receivers before the signal is given to the receiver circuitry the photon is multiplied with the photocurrent and this increases the sensitivity of the receiver since photocurrent is multiplied before encountering of the thermal noise associated with the receiver circuit.
