چکیده

The manuscript reports a study of Kr ion implantation in a Zn target in the 10-50 keV energy range at different source parameters, which combines experimental data and simulation with the SRIM package. The implanted thickness for the 45 keV was found to be 10 μm. The ion penetration depths for different films at different energies (10-50 keV) were calculated using SRIM computer program and found to be 100 Å at 10 keV and 475 Å at 40 keV. Theoretical calculations using SRIM-2000 have been performed to investigate the ion range. The dependence of ion beam currents on the accelerating voltage is given at discharge current equal to 0.8A and for various pressures. The krypton ion beam current reaches 3mA at 45KV for a pressure of 2 x 10-5Torr and a cathode current equal to 130A. An analysis has been made for an implanted krypton ion beam in a zinc specimen using laser ablation inductively coupled plasma mass spectrometry. Photographs show the examined zinc specimens are presented. The depth profile shows that the highest concentration of krypton ions under the surface of the zinc specimen is located at about 10 μm. © 2014 AESS Publications. All Rights Reserved.

Ultra-Sensitive CoUinear Fast Ion Beam Trace Detection of ̂ K̂r

A novel scheme of coUinear fast beam laser spectroscopy for the detection of the long lived rare isotope *^Kr by observing the optical hyperfme structure spectrum is presented. The technique utilizes cascade two-step excitation to pump metastable krypton atoms to a high-lying Rydberg level. The present work on krypton was motivated by the fact that *̂ Kr is a major tracer gas for exploring the r...

Nanosphere photolithography for sub-100nm features

Microfabrication is commonly achieved via interactions of light and a photoresist (an optically sensitive material). In this process, the light is shaped into the desired pattern by a mask and projected onto the photoresist. The entire photoresist sample is then submerged within a developer, which dissolves the exposed photoresist and leaves the unexposed photoresist intact. Mask patterns can t...

Electron impact fragmentation of size-selected krypton clusters.

Clusters of krypton are generated in a supersonic expansion and size selected by deflection from a helium target beam. By measuring angular distributions for different fragment masses and time-of-flight distributions for fixed deflection angles and fragment masses, the complete fragmentation patterns for electron impact ionization at 70 eV are obtained from the dimer to the heptamer. For each o...

Laboratory Astrophysics Survey Of Key X-Ray Diagnostic Lines Using A Microcalorimeter On An Electron Beam Ion Trap

Cosmic plasma conditions created in an Electron Beam Ion Trap (EBIT) make it possible to simulate the dependencies of key diagnostic X-Ray lines on density, temperature, and excitation conditions that exist in astrophysical sources. We used a microcalorimeter for such laboratory astrophysics studies because it has a resolving power .1000, quantum efficiency approaching 100% and a bandwidth that...
