A reusable metal clamp 10 for retaining a fused quartz ampoule 25 during temperature cycling in the range of 20. degree. C. to 1000. degree. C. A compressible graphite foil 27 having a high radial coefficient of thermal expansion is interposed between the fused quartz ampoule 25 and metal clamp 10 to maintain a snug fit between these components at all temperature levels in the cycle.

A pyroelectric detector array and the method for using it. A series of holes 13 formed through a silicon dioxide layer 12 on the surface of a silicon substrate 11 forms the mounting fixture for the pyroelectric detector array. A series of nontouching strips of indium 14 are formed around the holes 13 to make contact with the backside electrodes 16 and form the output terminals for individual detectors. A pyroelectric detector strip 15 with front and back electrodes 17 and 16, respectively, is mounted over the strips 14. Biasing resistors 18 are formed on the surface of the silicon dioxide layer and connected to the strips 14. A metallized pad 19 formed on the surface of layer 12 is connected to each of the biasing resistors 18 and to the film 17 to provide the ground for the pyroelectric detector array.

A wellbore tool comprising a power supply, an electrical load, a receiving unit configured to passively receive a triggering signal, and a switching system electrically coupled to the power supply, the receiving unit, and the electrical load, wherein the switching system is configured to selectively transition from an inactive state to an active state in response to the triggering signal, from the active state to the active state in response to the triggering signal, or combinations thereof, wherein in the inactive state a circuit is incomplete and any route of electrical current flow between the power supply and the electrical load is disallowed, and wherein in the active state the circuit is complete and at least one route of electrical current flow between the power supply and the electrical load is allowed.
