Two examples of capacitive pickups

Setup for inside-out experimentation

From Capacitively coupled pickup paper: A scaled comparison of capacitively coupled pulse and direct pulse on stripline pickup. Demonstrates that rise-time is the same and the pulse shape is only roughly affected.

From Capacitively coupled pickup paper: A scaled comparison of capacitively coupled pulse and direct pulse on 1'' pads. Demonstrates that rise-time is the same and the pulse shape is only roughly affected.

The differential time resolution vs 1/(Signal-to-Noise) as measured in the 8" test setup at the APS. The signals from the 2 ends of an 8" 30-strip anode are brought out to the scope and digitized. The MCP stack is a pair of 8" ALD-functionalized plates.
