Abstract
An image intensifier tube includes a microchannel plate (MCP) having conductive input and output surfaces disposed in a housing. A conductive lower support is in electrical contact with the output surface of the MCP, and a conductive upper support is disposed above the input surface of the MCP. A shape memory alloy (SMA) lockdown is disposed between the input surface of the MCP and the upper support. The SMA lockdown is configured to provide a lockdown for the MCP in the housing. An SMA upper surface is configured to provide an axial force against the upper support, and an SMA lower surface is in contact with the input surface of the MCP.
