Abstract
Abstract An apparatus for measuring of quantum radiation, particularly of gamma radiation, which comprises a first detector for the primary radiation, and a second detector for the back scattering radiation. A coincidence circuit and a measuring device are also provided. The first and second detectors are connected with the measuring device by means of the coincidence circuit. Both detectors have a high resolving power in spite of a complicated response function, and an adding device is connected with the detectors and the output of the adding device is connected with the measuring device.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
197 words
An apparatus for measuring of quantum radiation, particularly of gamma radiation, comprising a first detector means for receiving the primary gamma radiation and for scattering said primary gamma radiation thereby producing backscattering radiation, a second detector means disposed in the range of said backscattering radiation for receiving the latter and for producing a second detector signal substantially proportional to the energy of said backscattering radiation, said first detector means producing a first detector substantially proportional to the energy of a primary gamma radiation minus the energy of the corresponding backscattering radiation, a coincidence circuit means operatively connected to both said detector means, and a measuring device, both said detector means having a high resolving power in spite of a complicated response function, and an adding device operatively connected to both said first and second detector means for adding said first and second detector signals and the output of said adding device being operatively connected with said measuring device and a gate means actuated by said coincidence circuit and connected between said adding device and said measuring device for passing the output of said adding device to said measuring device upon receiving a signal from said coincidence circuit.
Claim 2
Independent Claim
197 words
An apparatus for measuring of quantum radiation, particularly of gamma radiation, comprising a first detector means for receiving the primary gamma radiation and for scattering said primary gamma radiation thereby producing backscattering radiation, a second detector means disposed in the range of said backscattering radiation for receiving the latter and for producing a second detector signal substantially proportional to the energy of said backscattering radiation, said first detector means producing a first detector substantially proportional to the energy of a primary gamma radiation minus the energy of the corresponding backscattering radiation, a coincidence circuit means operatively connected to both said detector means, and a measuring device, both said detector means having a high resolving power in spite of a complicated response function, and an adding device operatively connected to both said first and second detector means for adding said first and second detector signals and the output of said adding device being operatively connected with said measuring device and a gate means actuated by said coincidence circuit and connected between said adding device and said measuring device for passing the output of said adding device to said measuring device upon receiving a signal from said coincidence circuit.
Claim 3
Dependent Claim
16 words
