Description

Antiprotons can reflect from MCP surfaces. We aim to characterize this effect to inprove our diagnostics. By extracting particles from a pure antiproton plasma from the Cusp trap to the Cusp MCP in short bunches, we are able to measure their arrival times. If we make a histogram of arrival times, we expect a main peak upon first arrival, as well as multiple smaller peaks from reflections between the MCP and the trap. Biasing the MCP front would allow us to investigate this effect in different energy regimes.
