CONSTRUCTION AND CALIBRATION OF AN ANTI-COMPTON SPECTROMETER
Technical Report
·
OSTI ID:4031650
By suppressing the Compton response, the anti-Compton spectrometer emphasizes the photopeak without sacrificing resolution. The detector's response matrix was experimentally determined with five monoenergetic gamma sources. By interpolating between the known energies and extrapolating from the measured shapes, the response to gamma rays within the range 230 to 1460 kev was found. Applying the inverse response matrix to several line spectra unfolded the pulse- height spectra. The spectrometer is described, together with the determination of the response matrix. The spectrometer has a pulse-height resolution of 6.5 to 11% and a Compton suppression of 47 to 70%. (auth)
