Definition of ionization chamber in English:

ionization chamber

noun

  • An instrument for detecting ionizing radiation.

    • ‘To determine the beam size at the sample position, a knife-edge scan was performed and the beam intensity was measured with an ionization chamber placed downstream of the sample stage.’
    • ‘A conventional dosimetry system consisting of three parallel plate ionization chambers upstream of the sample holder was used.’
    • ‘This was used on his electroscopes and on his ionisation chambers for the work that he did with alpha particles.’
    • ‘For data analysis the diffraction patterns were corrected for uneven detector response and normalized to the ionization chamber, i.e., to the intensity of the incoming beam.’
    • ‘Ionization smoke detectors detect the presence of smoke using an ionization chamber and a source of ionizing radiation.’
    • ‘The beam intensity and sample absorption was monitored by two ionization chambers, placed before and after the sample, and by a PIN diode at the beamstop.’
