HERA particle accelerator: custom data analysis application

HERA particle accelerator: custom data analysis application

A custom data analysis application for studying beam lifetime disruption events in the electron beam loss monitors of HERA (electron-proton synchrotron particle collider).

HERA particle accelerator: electron Beam Loss Monitor lifetime disruption plots

The rate of beam loss monitor events from  lo  to  hi  is given as a coloured area plot over:

  • x-axis: time.
  • y-axis (lower): the index of the Electron Beam Loss Monitor (BLME) around the HERA electron storage ring.
  • y-axis (upper): the electron beam current.

Disruptions of the electron beam lifetime by charged macroparticles are revealed in the plots as slanted "hot" rate streaks. The novel plot strategy confirmed the existence, nature, scale and frequecny of the suspected disruptions.
