Abstract
We studied the guiding effect in a glass microcapillary array with similar dimensions as for a multi-channel plate (MCP) detector. At low impact energies (<10keV), no significant ion transmission was found. At higher energies, though the transmission after a transient period tended to be regular, temporary blocking and unexpected strong irregularities were found in the angular distribution of the transmitted ions during the early time evolution. Self-organizing seems to take over even after this chaotic period in the development of ion transmission.
Highlights
Synopsis: We studied the guiding effect in a glass microcapillary array with similar dimensions as for a Multi Channel Plate (MCP) detector
The guiding of highly charged ions through tilted nano- and microcapillaries were intensively studied in recent years
The guiding effect is due to the electrostatic charging up of the capillary wall by the incident ions, which deflects other ions to the capillary exit
