Abstract
A rugged scintillation crystal assembly includes several scintillator crystals, which are optically coupled to each other by resilient optical-coupling material such as silicone pads and/or grease. The scintillator crystals are configured to collectively emit optical signals. Such a stack may combine the advantages of both a long form-factor for the overall assembly with the ruggedness of the assembly's component short crystals.
Claims19
A system comprising:
- a casing for use in a logging-while-drilling tool;
- an optical window within the casing, wherein the optical window is configured to transmit an optical signal emitted within the casing to a device outside of the casing;
- a plurality of scintillator crystals within the casing, wherein the plurality of scintillator crystals are optically coupled to each other by resilient optical-coupling material, and wherein the plurality of scintillator crystals are configured to collectively emit optical signals to the optical window.
A method comprising:
- emitting a first optical signal, wherein the emitting is performed by a first scintillator crystal;
- receiving a second optical signal emitted by a second scintillator crystal, wherein the receiving is performed by the first scintillator crystal, wherein the optical signal is received via a resilient optical-coupling material, and wherein the resilient optical-coupling material is located between the first scintillator crystal and the second scintillator crystal;
- and
- optically transmitting the first optical signal and the second optical signal towards an optical window within a casing of a logging-while-drilling tool, wherein the casing houses the first scintillator crystal and the second scintillator crystal, and wherein the optically transmitting is performed by the first scintillator crystal.
