Abstract

A thermally induced current signal in a low noise polymeric coaxial cable can introduce errors in certain applications. The origin of such thermally induced signals is explained based on morphology and dielectric polarization as a function of temperature. The results of measurements carried out over a wide range of temperature are in good agreement with numerical simulations which involve the nonlinear thermal properties of the cable materials. For e-beam cross-linked polymeric cable, the thermally induced current signal can be as high as 1 nA/m
