  • The scintillation of CF4 and its relevance to detection

    Jan 30, 1995One can get the number of emitted photons using the relation for the probability of no photon detected, defined as zero-counting, by: P(O) = e-^- = e-s,n where ndet is the average number of detected photons, ny is the average number of photons emitted by a single a-particle interacting with the gas and 71 is the photon detection efficiency.Cited by: 107

  • Influence of rotor downwash on vertically displaced

    Jan 01, 2020As soon as CF4 arrived at its starting position above CF1, the flight behavior of CF1 became more unstable resulting in staggering of the copter, which is comparable to the flight behavior of a copter without installed optical motion detection system. This staggering behavior of CF1 increased during descent of CF4.
