Microchannel plate operation at high count rates new results
We describe an experimental study of two distinct microchannel plate MCP detector con gurations with extended dynamic range First we report on measurements made with single MCPs of very low resistance k bonded to a Peltier cooler Stable reproducible operation for a rear cooled MCP with m diameter channels of length to diameter ratio was achieved for biases up to V At this point the MCP strip cu...
متن کاملMean secondary electron yield of avalanche electrons in the channels of a microchannel plate detector
By modeling the statistical evolution of an avalanche created by 20 keV protons impacting the input surface of a z-stack microchannel plate ~MCP! detector, the mean secondary electron yield gC of avalanche electrons propagating through a MCP channel is measured to equal 1.37 for 760 V per MCP in the z stack. This value agrees with other studies that used MCP gain measurements to infer gC . The ...
متن کاملMicrochannel Plate Detectors
A microchannel plate (MCP) is an array of 104-107 miniature electron multipliers oriented parallel to one another (fig. 1); typical channel diameters are in the range 10-100 μm and have length to diameter ratios (α) between 40 and 100. Channel axes are typically normal to, or biased at a small angle (~8°) to the MCP input surface. The channel matrix is usually fabricated from a lead glass, trea...
متن کاملMonte Carlo Simulations of Microchannel Plate–Based, Time-Gated X-ray Imagers
In the last two decades, high-speed, time-gated Microchannel plate (MCP) x-ray detectors have proven to be powerful diagnostic tools for two-dimensional, time-resolved imaging and time-resolved x-ray spectroscopy in the field of laser-driven inertial confinement fusion and fast Z-pinch experiments (McCarville et al., 2005; Oertel et al., 2006; Bailey et al., 2004). These detectors’ quantitative...
متن کاملMicrochannel reactors for fast periodic operation: the catalytic dehydration of isopropanol
A microchannel reactor specially designed for periodic operation and a process to deposit a catalyst, -alumina, inside the reactor channels were developed. The hydrodynamics of the reactor was characterised. Although the #ow in the microchannels is laminar, a uniform radial concentration pro"le and consequently a narrow residence time distribution were obtained. Depending on the manufacturing m...
