Guiding of low-energy electrons by highly orderedAl2O3nanocapillaries

Focusing of charged particle beams with various glass-made optics

“…The results of simulations have explained the slow HCI transmission without touching the inner wall in terms of the dynamics of the charge-up distribution induced by the beam irradiation. The guiding of electron beams was also reported recently [23,24]. The phenomenon can be explained as follows: The incident ions entering the capillary hit the inner wall and consequently cause it to become charged.…”

Density effects on the guided transmission of 3keV Ne7+ ions through PET nanocapillaries

“…5), we make use of Eq. (2) by fitting the experimental results with a Gaussian-like function as done before [3,5,16]. Fig.…”

“…Due to the increasing interest in this subject, several laboratories started investigations of capillary guiding using PET [9][10][11], SiO 2 [12] and Al 2 O 3 [13][14][15]. Moreover, electrons were used as projectiles guided through capillaries in Al 2 O 3 [16] and PET [17]. Several contributions from different laboratories created a lively field with controversial discussions.…”

Study of electron transmission through a platinum tube

“…The first studies on electron guiding through insulating capillaries have been reported in 2007 [5,6], and followed by more detailed investigations [7][8][9]. The electron transmission through the capillaries appears to be fundamentally different from the simple picture of HCI guiding governed solely by Coulomb deflection [8,9].…”
