Description

Fast timing photosensors are critical for Nuclear Physics and High Energy Physics instruments. Microchannel plate photomultipliers (MCP-PMT) have compact electron amplification design, providing them with precision timing performance and excellent magnetic field immunity.

We report the development of MCP-PMTs with low-cost microchannel plates functionalized by the atomic layer deposition (ALD) technique at Argonne National Laboratory. Multiple photomultipliers were fabricated with different microchannel plate pore sizes and gap lengths. Their precision timing performance and magnetic field immunity were characterized and compared. To expedite the application of MCP-PMT for various programs, a $10 \times 10 cm^2$ MCP-PMT fabrication facility is under construction at Argonne to produce larger size, high-performance MCP-PMTs to fulfill R&D needs for various programs.
