摘要： A radiation logging tool is provided that includes a scintillator detector for use on a wellbore tool string to characterize earth formations. The scintillator detector has a shutter to allow for the collection of data differentiating between incident radiation, such as backscatter signal, and system noise, such as dark current, vibration noise, electronics thermal noise, and electrostatic noise. The radiation logging tool provides for a method of calibrating and measuring incident radiation by the removal of system noise. The shutter is positioned between the photosensor and scintillation member of the scintillator detector, and is able to switch between open and closed states while the scintillation detector is deployed. Measurements of signal noise can be used to calibrate the sampling signal of incident radiation on the scintillator detector.

摘要： Apparatus and methods for determining the rock solid (matrix) dielectric permittivity for subterranean rocks, such as carbonate rocks, are described. According to some embodiments, this is accomplished by linking the matrix permittivity to the detailed chemical composition of the rock. The linking function is defined by coefficients for each component that can be determined by inversion in a laboratory calibration process such that the function compensates for the permittivity contribution of rock components that may be undetectable through downhole logging procedures.

An elongate electrode extends within the housing and has opposing first and second ends, with the first end secured to adjacent portion of the housing. The elongate electrode has second thermal expansion over the operating temperature range defining a difference with respect to the first thermal expansion. A temperature compensator is coupled between the second end of the elongate electrode and an adjacent portion of the housing. The temperature compensator has a third thermal expansion over the operating temperature range to maintain a tension on the elongate electrode within a desired range over the operating temperature range.

摘要： An ion source for use in a particle accelerator includes at least one cathode. The at least one cathode has an array of nano-sized projections and an array of gates adjacent the array of nano-sized projections. The array of nano-sized projections and the array of gates have a first voltage difference such that an electric field in the cathode causes electrons to be emitted from the array of nano-sized projections and accelerated downstream. There is a ion source electrode downstream of the at least one cathode, and the at least one cathode and the ion source electrode have the same voltage applied such that the electrons enter the space encompassed by the ion source electrode, some of the electrons as they travel within the ion source electrode striking an ionizable gas to create ions.
