Abstract: A radiation detection device includes a sensor having a first electrode and a second electrode. The first and second electrode each defines a plurality of fingers comprising a nanotube material, and the fingers of each electrode are interdigitated with one another. A voltage source may be configured to apply a voltage across the first and second electrodes. A chamber contains the sensor with a gas, one or more walls of the chamber enabling passage of radiation external to the chamber. A detection circuit detects radiation within the chamber based on a change in current across the first and second electrodes resulting from ionization of the gas by the radiation.

Abstract: A slickline that includes both electrically conductive and fiber optic capacity. The slickline includes a fiber optic thread or bundle of threads disposed in a support tube and surrounded by an electrically conductive member such as tightly wound copper threads. In certain embodiments, the electrically conductive member may be provided in direct contact with the support tube without the requirement of an insulating layer. Alternatively, the tube itself may be foregone with a channel for the fiber optic thread or bundle defined by insulating material about the electrically conductive member. Either way, the overall profile of the slickline may advantageously be kept to a minimum.
