TIME-OF-FLIGHT TECHNIQUE FOR PARTICLE IDENTIFICATION AT ENERGIES FROM 2-400-KEV-NUCLEON

We have extended the time-of-flight for particle identification to 2 keV/nucleon and reduced the size of the start-time detector considerably by the use of carbon foils of few μm cm-2 in thickness combined with microchannel plates for detecting secondary electrons. Time-of-flight telescopes incorporating this start-time device have been used to measure the stopping power of a number of low energy heavy ions in thin carbon foils and the charge states of these ions emerging from such foils. Applications of this technique for the detection and identification of low energy interplanetary and magnetospheric particles are suggested. © 1979.
