Gamma-ray detectors for the detection of one or more gamma-rays are provided. Also provided are methods of using the detectors for the detection of one or more gamma-rays. The detectors can be used in high-spatial resolution PET systems, including time-of-flight (TOF)-PET systems. Some of the gamma-ray detectors utilize fluors and an optical imaging system to determine the time and location of a first scattering event of a gamma-ray in a low atomic number scintillating medium. Some of the gamma-ray detectors determine the time and location of a first scattering event of a gamma-ray in a low-density scintillating medium by imaging scintillation photons from the scattering event as a time-series of photon 'rings' using a planar pixelated photodetector as a scintillation photon counter.

Systems and methods for the batch production of large numbers of highly uniform multichannel-plate photomultiplier tubes (MCP-PMTs) for large-scale applications are provided. The systems and methods employ dual, nested low-vacuum (LV) and UHV processing in a rapid-cycling, small-footprint, scalable, batch-production facility that is capable of fabricating many MCP-PMTs simultaneously.

A system for type-2 ghost imaging of an object located in or obstructed by a turbulent air section includes a thermal light source, a beamsplitter configured to split light from the thermal light source into two optical paths of substantially equal length, a surface divided into two regions of equal area, a first region including the object and a second region that does not include the object, a narrowband spectral filter, and at least one detector having a predetermined spatial resolution and a predetermined temporal resolution. The object is located on one side of the turbulent air section and the at least one detector is located on another side of the turbulent air section. The at least one detector may be a large area picosecond photo-detector (LAPPD) having a spatial resolution of the order of millimeters and a temporal resolution of the order of 10 to 100 picoseconds.

A material preferably in crystal form having a low atomic number such as beryllium (Z=4) provides for the focusing of x-rays in a continuously variable manner. The material is provided with plural spaced curvilinear, optically matched slots and/or recesses through which an x-ray beam is directed. The focal length of the material may be decreased or increased by increasing or decreasing, respectively, the number of slots (or recesses) through which the x-ray beam is directed, while fine tuning of the focal length is accomplished by rotation of the material so as to change the path length of the x-ray beam through the aligned cylindrical slots. X-ray analysis of a fixed point in a solid material may be performed by scanning the energy of the x-ray beam while rotating the material to maintain the beam's focal point at a fixed point in the specimen undergoing analysis.

Active optics apparatus and method for aligning active optics are provided for a high-resolution, active optic fluorescence analyzer combining a large acceptance solid angle with wide energy tunability. A plurality of rows of correctors selectively controlled to bend an elongated strip of single crystal material like Si (400) into substantially any precisely defined shape. A pair of pushers engages opposite ends of the silicon crystal strip exert only a force along the long axis of the crystal strip, and does not induce additional bending moments which would result in a torsion of the crystal.
