An improvement to nuclear track counting systems using laser light scattering
In this work we present a device to measure the angular distribution of the diffuse optical transmittance produced by etched nuclear tracks in a polyallyl diglycol carbonate (PADC) detector. The device makes use of a stepper motor to move an array of four photodetectors around the sample in 1.8-degr...

| Sumario: | In this work we present a device to measure the angular distribution of the diffuse optical transmittance produced by etched nuclear tracks in a polyallyl diglycol carbonate (PADC) detector. The device makes use of a stepper motor to move an array of four photodetectors around the sample in 1.8-degree steps. The effect of additional scatterers is reflected in the width at half height of the angular distribution curves. The width at half height was found to be a linear function of the nuclear track density in the range from zero to 2.8x 10(5) cm-2. An Am-Be neutron source was used. |
