Results from a 40 mm intensifier using a multilayer ceramic imaging element

We describe a highly versatile 40 mm diameter microchannel plate intensifier tube using an electronic image read out manufactured in a collaboration between the Mullard Space Science Laboratory and EEV. A development programme is underway to demonstrate photon imaging using a variety of charge division image read-out designs all of which are accommodated in a new generic tube design. Each read out is aimed for maximum performance at a specific region of the resolution versus dynamic range envelope, from high-speed, moderate resolution (10 MHz, 64 pixel) to ultimate resolution (100 kHz, 4000 pixel). neric tube design utilizes a multilayer ceramic component which forms the tube vacuum vessel rear flange, while also acting as a 26 contact electrical feedthrough and as a substrate for the read-out anode. The output pins of the ceramic are arranged to mate with an industry-standard multipole socket for easy connection and replacement. This component provides a much more compact and robust solution to the integration of the electronic read out with the intensifier than is commonly seen with this technology. her novel element in the design is a semi-transparent grid above the anode used to control secondary electron emission, an effect which can compromize imaging performance. sent results from initial testing of the device.
