TL;DR: The unique possibilities enabled by neutron imaging for in situ remote diagnostics of microstructural characteristics during crystal growth are demonstrated, even when the materials and surrounding structures are opaque to other more conventional interrogation techniques.

Abstract: We present details of the design of a micro‐channel based photon counting image‐tube developed for ground‐based visible astronomical observations with a timing precision <1 micro‐sec. The image‐tube, developed at UC Berkeley, was subsequently attached to the prime focus of the 40 inch Nickel telescope at the Lick Observatory to obtain high time resolution photometric data on a variety of objects that included the Crab pulsar, cataclysmic variable stars (BG CMi, SU UMa) and dMe‐type flare stars (FL Vir and V1054 Oph). We report on preliminary scientific results from these data and outline some of the specialized observational techniques required to successfully carry out observations with such detector systems at high time resolution. Further developments of the detector system to enhance its performance are underway and will be described, as well as other potential applications such as high time resolution polarimetry.

TL;DR: In this paper, the absolute quantum efficiency of polycrystalline diamond films grown on silicon substrates by chemical vapor deposition (CVD) was reported in the range of 25-200 nm.

TL;DR: In this article, the authors demonstrate the feasibility of imaging periodic dynamic magnetic fields using a spin-polarized cold neutron beam, which can be used for mapping of a magnetic field distribution, as demonstrated previously for static magnetic fields at neutron beamline facilities.

TL;DR: In this article, the authors demonstrate the possibility to image and distinguish NiO and Ni phases within SOFC anode supports by energy-resolved neutron imaging and the potential of the neutron imaging method for in situ studies of reduction processes.
