A 'no-beam' failure starts when the beam current drops below the current  $I_{\hbox{min}}$; a 'low-beam-current' already starts below the current limit  $I_{\hbox{tol}}$ (if it isn't a 'no-beam' failure).   Both modes stops when the nominal beam current $I_{\hbox{nom}}$ is reached again. \lable{fig:primary-failure-modes}
