LAPPD Figures for Papers and Talks

Shape comparison

111

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.

Shape comparison pads

110

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.

Pulse comparison strips

109

From Capacitively coupled pickup paper: Comparison of unscaled pulses, both from NiCr capacitive and Direct configurations, on stripline pickup

Pulse comparison pads

108

From Capacitively coupled pickup paper: Comparison of unscaled pulses, both from NiCr capacitive and Direct configurations, on 1'' pad pickups

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.
