“…However, despite it being a fast cooling process compared to IR emission, this fluorescence is actually slow with a typical lifetime larger than 1 ms. Ion storage techniques are needed to study decay processes on such a time scale. Linear or bend electrostatic ion-beam storage traps (EIBT) or rings [19][20][21][22][23][24][25][26][27][28] have been developed to study the dynamics of delayed photofragmentation, electron photodetachment, and photoionization processes for time scales between microseconds and a few tens of milliseconds. With these devices, it becomes possible to get insight into cooling rates by monitoring neutral dissociation products and following the evolution of the internal energy distribution (IED) of the stored molecular ensemble.…”

Fast radiative cooling of anthracene cations (C 14 H 10 ) + is studied with a compact electrostatic storage device, the Mini-Ring. The time evolution of the internal energy distribution of the stored ions is probed in a time range from 3 to 7 ms using laser-induced dissociation with 3.49-eV photons. The population decay rate due to radiative emission is measured to vary from 25 to 450 s -1 as a function of the excitation energy in the range from 6 to 7.4 eV. After corrections of the infrared emission effect via vibrational transitions, the fluorescence emission rate due to electronic transitions from thermally excited electronic states is estimated and compared with a statistical molecular approach. In the considered internal energy range, the radiative cooling process is found to be dominated by the electronic transition, in good agreement with our previous work [S. Martin et al.,

“…The third electrode is a central ring that serves as the electrostatic potential reference. A similar cone-trap was used in Lyon in a single ion-trapping mode to investigate the stability and the fragmentation of multiply charged fullerene C r+ 60 (r = 3-6) ions [63,64]. In this experiment, C r+ 60 ions were formed by electron capture in collisions between highly charged ions and neutral C 60 .…”

This paper presents an introduction to the application of ion traps and storage devices for cluster physics. Some experiments involving cluster ions in trapping devices such as Penning traps, Paul traps, quadrupole or multipole linear traps are briefly discussed. Electrostatic ion storage rings and traps which allow for the storage of fast ion beams without mass limitation are presented as well. We also report on the recently developed mini-ring, a compact electrostatic ion storage ring for cluster, molecular and biomolecular ion studies.

“…Electrostatic ion storage devices such as electrostatic ion-beam traps 26–30 or electrostatic ion-beam storage rings 31–36 are well suited for studies of the dynamics of molecular processes in the ms to second time-range 37 such as spontaneous or thermionic electron emission, 38–41 unimolecular statistical dissociation, 27,42 slow isomerization 43 or radiative cooling, 44–48 processes where rates may vary over several orders of magnitude depending on the internal energy.…”
