Permanent polarization in pyroelectric TGS ir detectors due to X-rays (TriGlycine Sulphate crystals)

The dielectric constant, pyroelectric coefficient, and loss tangent of triglycine sulphate (TGS) crystals that had been poled and subsequently irradiated with X-rays are presented as a function of X-ray exposure and temperature. The results are compared with similar measurements made on poled Co-60...

Description
Summary:The dielectric constant, pyroelectric coefficient, and loss tangent of triglycine sulphate (TGS) crystals that had been poled and subsequently irradiated with X-rays are presented as a function of X-ray exposure and temperature. The results are compared with similar measurements made on poled Co-60 gamma irradiated TGS. An estimated X-ray dosage of 1.5-2.0 Mr per min for 1-2 min gave equivalent results to 2.3 Mr of Co-60 gamma rays in achieving optimum non-ferroelectric pyroelectric behaviour in TGS ir detectors.
