Beam Stabilization and Instrumentation Systems based on Internet of Things Technology

Abstract

A longitudinal coupled bunch mode diagnostic was built to identify and characterize coupled bunch modes in the Max IV 3 GeV ring. A longitudinal coupled bunch Mode 0 dipole instability was identified and a longitudinal Mode 0 dipole damper was built which cured the instability. As a separate project, a radio frequency current transformer was built as an emergency backup to the DC current transformer. All the devices where built using the open-source Blinky-Lite Internet of Things platform that enabled quick and inexpensive deployment.
