Abstract: This disclosure is directed to a dosimeter that may be utilized in FLASH radiotherapy (FLASH-RT) applications. The dosimeter is capable of responding on small time scales while simultaneously maintaining a well-defined response with ultra-high dose rates. The dosimeter is capable of real-time and in-situ control and monitoring of beam delivery, which beneficially enhances the safety and accuracy of FLASH-RT treatments.

Abstract: This invention relates to a sensor device consisting of long period gratings made of rare-earth doped double clad fiber, which is written by CO2 laser irradiation while the fiber is held static, for gamma dose measurement in the range of 150 Gy-2.5 kGy, extendable to 20 kGy, which measurements are real-time and can be from remote locations. The sensor device has high wavelength dip shift sensitivity of at least 2.8 nm/kGy, and its radiation-induced changes are near permanent. The gratings demonstrate negligible temperature sensitivity and the shifts recorded show negligible annealing at room temperature.

Abstract: According to one embodiment, a scintillator includes a first layer provided on a surface of a substrate and including thallium activated cesium iodide; and a second layer provided on the first layer and including thallium activated cesium iodide. The second layer includes crystals having a [100] orientation partially diverted from a direction perpendicular to the surface of the substrate. Half width at half maximum of a frequency distribution curve of an angle between the direction perpendicular to the surface of the substrate and the [001] orientation, which is obtained by measuring the angle using EBSD method, is 2.4 degree or less.

Abstract: A photon radiation detection systems utilizes scintillating fibers to detect downhole radioactivity along a wellbore. The system includes a light detection unit, extended light guide, and a scintillating fiber radiation detector extending along a wellbore. The scintillating fiber radiation detector may be a permanent part of the wellbore completion, or may be deployed via a downhole conveyance. The detected light photons may be utilized to evaluate the formation, cement layer or tubular string.

Abstract: A radiation detection system comprising a detection grid of wavelength shifting fibers with a volume of scintillating material at the intersecting points of the fibers. Light detectors, preferably Silicon Photomultipliers, are positioned at the ends of the fibers. The position of radiation is determined from data obtained from the detection grid. The system is easily scalable, customizable, and also suitable for use in soil and underground applications. An alternate embodiment employs a fiber grid sheet or layer which is comprised of multiple fibers secured to one another within the same plane. This embodiment further includes shielding in order to prevent radiation cross-talk within the grid layer.

Abstract: A wave guide face plate for transmitting an image formed in a scintillating material included as part of a transmitting medium is disclosed. The transmitting medium includes a random distribution of different refractive index regions in two orthogonal dimensions, and an essentially consistent refractive index in a third orthogonal dimension. The third orthogonal direction is aligned with a transmission axis of the wave transmitter extending from an input location to a wave detector location. The transmission efficiency of the wave guide faceplate is improved in situations where the entry angle of the input radiation is different from the axis of the wave transmitter as compared to conventional faceplates.
