55 Developing Large-area Psec Timing: The MCP Return-Path Problem and a Proposed Solution

Original Uploaded File: Download anode.pdf

Description: July 20, 2006 One limiting factor in the speed of a 2"x2" MCP is the inductance in the path that charge has to ow from the anode back to the source of the charge, the micro-channel plate output. In this note we propose a solution to the MCP problem that uses a grid in the anode plane and a small MCP-OUT physical gap to provide a fast capacitative return path. We provide the physical dimensions and a specication of the anode we would like implemented in an MCP optimized for timing, hopefully the next MCP of the four we have ordered from Burle/Photonis
