Abstract
A detector probe, for detecting ionizing radiation and which is suitable for use in a nucleonic instrument usable in locations having a high ambient temperature, includes an array of radiation detectors mounted on a support and a heat pipe for cooling the detector probe. The nucleonic instrument incorporating such a detector probe is also described.
Claims12
A nucleonic instrument for measuring a characteristic of one or more material phases within a container, comprising:
- at least one source of ionising radiation comprising alpha particles, beta particles, gamma radiation and/or neutrons;
- at least one detector probe configured for detecting said ionising radiation comprising a linear array of radiation detectors spaced apart along a heat pipe for cooling the detectors, the detectors being mounted in thermal contact with and physically supported on the heat pipe;
- a power source;
- and
- an electronic apparatus comprising a control unit and a signal and data processing means for calculating a characteristic of the material phases using signals generated by the detectors in response to radiation received from the radiation sources,
- wherein the nucleonic instrument is a level gauge or a density profiler.
