Journal ArticleDOI

H2 and rare gas field ion source with high angular current

TL;DR: In this paper, a field ion source was designed to operate at very low temperatures with a physisorbed surface supply to the ionization region, which was found to give beams of high angular current density and is expected to have low energy spread in the beam.
Journal ArticleDOI

Synchronous digestion of SV40 DNA by exonuclease III.

TL;DR: A new method for determining the sequence of long duplex DNA can be realized through synchronous digestion of the DNA from the 3' ends with exonuclease III, followed by repair synthesis with labeled nucleotides and DNA polymerase and sequence analysis of the repaired DNA.
Journal ArticleDOI

Relaxed circular SV40 DNA as cleavage intermediate of two restriction endonucleases

TL;DR: The mode of cleavage of superhelical SV40 DNA (Form I) by restriction endonucleases EcoRI and HpaII at 37 degrees C is determined and a kinetic reaction scheme for both enzymes is proposed.
Journal ArticleDOI

High resolution structuring of emitter tips for the gaseous field ionization source

TL;DR: In this article, a method using ion milling for configuring surface contour on both microscopic and near atomic length scales which utilizes the morphological changes occurring at ion bombarded surfaces as a result of erosion by sputtering is presented.
Journal ArticleDOI

Quantitative reflection electron diffraction in an ultra high vacuum camera

TL;DR: In this paper, an ultra high vacuum electron diffraction camera for intermediate energies (10-50 kV) is described, where a Faraday cup scans the diffraction pattern while another monitors the incident beam, reading out the intensities with high accuracy.
