Abstract

We report recent progress on microchannel plate (MCP) sealed, high-vacuum devices and open-face architectures. These can be configured with UV transmissive windows, bi-alkali or alkali-halide opaque photocathodes and atomic layer deposited (ALD) MCPs. Detectors with 100cm² cross-strip (XS) readouts are currently under development, and we discuss our results with newly fabricated hermetic, high temperature co-fired ceramic XS anodes. We employ event driven electronics and make initial performance assessment of these new sensing elements. We also discuss the implementation of a first-generation GRAPH ASIC that couples charge sensitive amplification and digitization for XS signal conversion in a low power, small format. The approaches shared serve as candidates for creating large focal planes that can meet the requirements of future flagship UV missions. They also constitute a tailorable option for the community and can support smaller missions with a variety of detector formats.
