Temperature dependence of ion formation in the nuclear track plasma

Secondary ion emission from condensed CO bombarded by fission fragments

“…[1][2][3][4][5][6][7][8]. Motivation for such studies comes from material science [1], molecular physics [2][3][4][5] and astrophysics [6][7][8].…”

Secondary ion emission from CO2–H2O ice irradiated by energetic heavy ions

“…The method used to identify and characterize the ionic species produced in the surface layers of CO 2 -H 2 O ice is time-of-flight secondary ion (SI ± ) mass spectroscopy, TOF SIMS [6], which has been used to analyze other frozen-gas targets (e.g., [7][8][9]). The ice was irradiated by MeV nitrogen ions, which eject from the ice surface the produced atomic and molecular ionic species into vacuum.…”

Characterization of clusters produced by 252Cf fission fragment impact on a N2 ice target

“…The experimental features of 252 Cf-PDMS can be found elsewhere [1,5,7,27]. Briefly, an N 2 ice target was grown by condensation of N 2 gas over an Au substrate at controlled low temperature (in the 30-40 K range).…”

“…The desorbed ions are accelerated by an extraction field towards the drift region and are detected by a micro channel plate detector. The mass analysis is performed by the time-of-flight technique (TOF) [27].…”

“…Some insights on the cluster production and ionization mechanisms can be extracted from the fitting of the experimental population values, using the stability analysis results. We can assume that each series contributes exponentially to the mass spectra, since this behavior is characteristic of FF experiments [1,5,7,27]. Also, since the cluster mass varies almost linearly with its energy (see Fig.…”
