Paper Abstract

A large area, high resolution detector containing microchannel plates (MCPs) and a helical wire wound delay line anode is currently being fabricated. We describe the performance of another recently constructed device with a similar design, and discuss design modifications which will result in improved performance from the current detector. In particular, we describe a modified delay line anode designed to read out the same size MCPs (100 mm X 100 mm) as in the earlier tube, but with more compact size, lower attenuation, and less dispersion. Results are presented of measurements of pulse risetimes and attenuation, and of anode geometric linearity and resolution as a function of MCP charge.
