Fast Position- and Time-Sensitive MCP-Detectors

Fast Position- and Time-Sensitive MCP-Detectors

Detector with Delay-Line Readout DLD40

Microchannel-Plate detector with delay-line readout for electron, ion photon (x-ray and UV) and neutron detection

Digital electronic readout measures position and time simultaneously and enables highest count rates

UHV-compatible

Detector with Delay-Line Readout
