Needs, trends, and advances in scintillators for radiographic imaging and tomography / Wang, Zhehui (Los Alamos) ; Dujardin, Christophe (ILM, Lyon) ; Freeman, Matthew S. (Los Alamos) ; Gehring, Amanda E. (Los Alamos) ; Hunter, James F. (Los Alamos) ; Lecoq, Paul (CERN) ; Liu, Wei (Mayo Clinic) ; Melcher, Charles L. (U. Tennessee, Knoxville) ; Morris, C.L. (Los Alamos) ; Nikl, Martin (Prague, Inst. Phys.) et al.
Scintillators are important materials for radiographic imaging and tomography (RadIT), when ionizing radiations are used to reveal internal structures of materials. Since its invention by Röntgen, RadIT now come in many modalities such as absorption-based X-ray radiography, phase contrast X-ray imaging, coherent X-ray diffractive imaging, high-energy X- and γray radiography at above 1 MeV, X-ray computed tomography (CT), proton imaging and tomography (IT), neutron IT, positron emission tomography (PET), high-energy electron radiography, muon tomography, etc. [...]

Unique capabilities and applications of Microchannel Plate (MCP) detectors with Medipix/Timepix readout / Tremsin, A S (UC, Berkeley (main)) ; Vallerga, J V (UC, Berkeley (main))
The development of highly pixelated fast Medipix/Timepix readout enabled a large number of novel hybrid detectors, where incoming particles/photons are initially converted into a measureable charge, typically exceeding 1000 electrons. Among those possible converters are Microchannel plate (MCP) electron multipliers, which provide some unique capabilities when combined with bare Medipix/Timepix readout. [...]

Single-photon imaging detector with O (10) ps timing and sub-10 μm position resolutions / Fiorini, M (INFN, Ferrara ; Ferrara U.) ; Alozy, J (CERN) ; Bolognesi, M (INFN, Ferrara ; U. Ferrara (main)) ; Campbell, M (CERN) ; Ramusino, A Cotta (INFN, Ferrara ; U. Ferrara (main)) ; LLopart, X (CERN) ; Michel, T (MPI Sci. Light, Erlangen) ; Schifano, S F (INFN, Ferrara ; Ferrara U.) ; Tremsin, A (UC, Berkeley) ; Vallerga, J (UC, Berkeley)
We present the concept of a single-photon imager capable of detecting up to 109 photons per second with simultaneous measurements of position (5–10 μm resolution) and time (few tens of picosecond resolution) for each individual photon over an active area of 7 cm2. The detector is based on a "hybrid" concept: a vacuum tube, with a transparent input window on which a suitable photocathode material is deposited, a micro-channel plate and a pixelated read-out anode designed in 65 nm CMOS technology.

Noiseless imaging detector for adaptive optics with kHz frame rates / Vallerga, J V ; McPhate, J ; Mikulec, Bettina ; Tremsin, A ; Clark, Allan G ; Siegmund, O H W /Medipix Collaboration
A new hybrid optical detector is described that has many of the attributes desired for the next generation AO wavefront sensors. The detector consists of a proximity focused MCP read out by four multi-pixel application specific integrated circuit (ASIC) chips developed at CERN (â€ワMedipix2”) with individual pixels that amplify, discriminate and count input events.

A high resolution, high frame rate detector based on a microchannel plate read out with the Medipix2 counting CMOS pixel chip. / Mikulec, Bettina ; Vallerga, J V ; McPhate, J B ; Tremsin, A S ; Siegmund, O H W ; Clark, Allan G /Medipix Collaboration
The future of ground-based optical astronomy lies with advancements in adaptive optics (AO) to overcome the limitations that the atmosphere places on high resolution imaging. A key technology for AO systems on future very large telescopes are the wavefront sensors (WFS) which detect the optical phase error and send corrections to deformable mirrors. [...]
