GAMMA INDUCED PHOTOCONDUCTIVITY IN A POLYETHLENE TEREPHTHALATE CAPACITOR

Abstract

Gamma-induced photoconductivity was measured in a Mylar (polyethylene terephthalate) capacitor over a range of flux from 100 R/sec to 4,000,000 R/sec. The results generally agree with data of other researchers and with the semiempirical relationship: S = Kg to the l power; where S = photoconductivity, 1/(ohm-cm); g = gamma flux, R/sec; K = a constant of proportionality characteristic of the material; l = an exponent, also characteristic of the material. A least squares fit of this curve to the data yields values of K = (6.2 ! 0.6) x 10 to the -19th power 1/(ohm-cm) R/sec and 1 = 1.11 ! 0.01. (Author)
