GAS IONIZATION DETECTOR AND TOMODENSITOMETER USING SUCH A DETECTOR

摘要

P IONIZATION CHAMBER DETECTOR FOR ELIMINATING INTERFERED SIGNALS GENERALLY DUE TO DEFORMATIONS OF THE STRENGTHS OF THE STRENGTH OF THE ELECTRIC FIELD CREATED BETWEEN THE ELECTRODES OF THE IONIZATION CHAMBER, DEFORMATIONS LOCATED AT THE END OF THESE ELECTRODES. /P P THIS DETECTOR INCLUDES A SEALED IONIZATION CHAMBER IN TWO COMPARTMENTS C, C BY MEANS OF A PARTITION M OF PERMEABLE DIELECTRIC MATERIAL WITH AN IONIZING RADIATION BEAM. IN THE C DOWNSTREAM COMPARTMENT ARE PROVIDED MEASURING ELECTRODES E, E ... AND IN THE COMPARTMENT C GUARDED ELECTRODES E, E ... RESPECTIVELY COPLANAR AND RELEASED TO THE SAME POTENTIALS V, V AS THE MEASURING ELECTRODES E, E ... THE GASES INTRODUCED UNDER THE SAME HIGH PRESSURE INTO COMPARTMENTS C, THERE ARE DIFFERENT ATOM NUMBERS. /P P APPLICATION: TOMODENSITOMETER. /P
