DESCRIPTION:Speakers: Askar Issatov (Joint Institute for Nuclear Research\
 , Flerov Laboratory of Nuclear Reactions)\nTime-resolved ion beam induced 
 luminescence (ionoluminescence\, IL) measurements\, especially those when 
 the luminescence decay is registered after single ion impact may be effici
 ently used for real-time characterization of irradiating materials. Tempor
 al resolution of single ion technique\, not limited by beam pulse duration
  has enabled to reveal new interesting features in dynamics of dense elect
 ronic excitations in vicinity of swift ion trajectory [1\,2]. The start pu
 lses in such experiments are produced using electron emission from carbon 
 foils generated by incoming ion. In this report we present the design of t
 he IL detection system at IC-100 FLNR JINR cyclotron in which the start pu
 lses are formed using electron emission immediately from the target surfac
 e. Such approach allows to narrow the instrumental response function and m
 inimize inaccuracy in lifetime measurements arising due to dispersion in i
 on velocities. The experimental set-up has been used for studies of time-r
 esolved ionoluminescence of intact and pre-damaged Al2O3 single crystals d
 uring single 1.2 MeV/amu Ne\, Ar\, Kr and Xe ion impact.\n1. Kazuie Kimura
