“…Stable equilibrium was never reached even for large integrated charge due to sharp oscillations in the transmitted intensity, indicating a mechanism of sudden discharge followed by slower recovery. The features are different from what has been observed experimentally so far for electrons [11,12] or for slow positive ions [1][2][3][4][5][6][7][8][9][10]. Also, our results for this single macroscopic-sized glass capillary are contrary to simulations for electron guiding through an array of polyethylene terephthalate (PET) nanocapillaries [14].…”

“…In fact, investigations [10] with glass capillaries have observed multiple oscillations of the transmitted beam position on a position sensitive detector, suggesting the dynamics of the charging process are in agreement with a charge patch model.…”

“…However, compared to the enormous amount of research for slow ions [1][2][3][4][5][6][7][8][9][10], so far little has been done to investigate electron transmission dynamics, experimentally [11][12][13] or theoretically [14]. Consequently, many questions regarding the transmission process remain unanswered.…”

Time evolution of electron transmission through a single glass macrocapillary: Charge build-up, sudden discharge, and recovery

et al. 2011

The time (i.e., integrated charge) dependence of electron transmission through a single glass macrocapillary was studied for incident 500-and 800-eV electrons at different capillary tilt angles. As the transmitted intensity goes to equilibrium, the centroid energies and corresponding energy values of the full width at half maximum of the transmitted electron distributions are found to vary in phase and out of phase with the transmitted intensity, respectively. Stable equilibrium was not fully reached even for large integrated charge due to sharp oscillations in the transmitted intensity. Plots of the recovery charging curves after breakdown show larger charge constants for the first recovery, but subsequently show smaller values that are about equal to one another for a given beam energy. Previously, such oscillations and recovery have not been reported for electrons.

“…ac.cn of areal beam density at the outlet to that at the inlet. Several experiments [10,[22][23][24] have indicated that charged ions can well be focused by a tapered single glass capillary. Theoretical simulation [25] demonstrates that this focusing factor depends on the shape of the capillary and its dimension and material properties.…”

Double-peak structures in transmission ofH2+ions through conical multicapillaries in a polymer: Projectile-energy dependence

et al. 2015

View full text Add to dashboard Cite

Transmission experiments o f7-200 keV H2+ ions through conical multicapillaries with inlet or outlet diameters of 4/2 gm and a length of 30 g m etched in a PC polymer are reported. The yield of the transmitted particles as a function of the capillary tilt angle was measured. The results show that for 200 keV H2+ ions the guiding effect disappears but a focusing effect is obtained with a density enhancement factor of 3.5. For 7-50 keV H2+ ions their transmitted particle curves exhibit a pair of shoulder peaks on the left-and right-hand side of the center angle 0 . As the ion energy increases, the shoulder-peak structure is found to vanish leaving one peak at 0°.

“…Recently, systematic works have been started measuring and analyzing the time evolution of the angular transmission profiles [5,6,[21][22][23]. Pronounced oscillations have been observed in the angular position of the ion-transmission profiles, providing evidence for the formation of temporary charge patches produced in the interior of the capillary besides the primary charge patch created in the entrance region [6].…”

Ion guiding accompanied by formation of neutrals in polyethylene terephthalate polymer nanocapillaries: Further insight into a self-organizing process

et al. 2010

A relatively large yield of neutralized atoms was observed when 3 keV Ar 7+ ions were guided trough polyethylene terephthalate nanocapillaries. Time and deposited-charge dependence of the angular distribution of both the guided ions and the neutrals was measured simultaneously using a two-dimensional multichannel plate detector. The yield of neutrals increased significantly faster than that of guided ions and saturated typically at a few percent level. In accordance with earlier observations, both the yield and the mean emission angle of the guided ions exhibited strong oscillations. For the atoms, the equilibrium was achieved not only faster, but also without significant oscillations in yield and angular position. A phase analysis of these time dependencies provides insight into the dynamic features of the self-organizing mechanisms, which leads to ion guiding in insulating nanocapillaries.
