RADIOLOGISTS routinely are required to view radiographs to identify the presence or absence of disease or other malady. After careful exposure from a uniform x-ray source and careful processing, the most common way of viewing a radiograph is to place it on a viewbox. Viewboxes, however, are constructed rather inexpensively using fluorescent bulbs, reflectors and diffusers to spread the light over an area the size of an x-ray. Simple electro-optic measurements show that the luminance of the viewb...

Microchannel plates (MCPs) are compact electron multipliers of high gain, widely used for the high resolution imaging of charged particles and photons. In this paper, we consider the use of lead glass MCPs for the imaging of thermal neutrons. Two contrasting techniques are described. The first method involves direct neutron detection within a special channel plate structure containing lithium and/or boron. We review the constraints of glass chemistry on the attainable lithium oxide and boron oxi...
