STUDY OF BUBBLE DAMAGE DETECTORS FOR NEUTRON DETECTION

Bubble damage detectors have been prepared by using polyacrylamide as detector solid and freon as detector liquid. Tests show that the prepa red detectors are sensitive to fast neutrons and have proportionality between bubble number and neutron fluence within a certain range of ne utron fluence. Therefore, it can be used as a fast neutron detector an d a dosimeter. Our experiments also show that the sensitivity of the d etector increases with temperature.
