In order to develop the photo cathode gun for the Compact ERL (cERL), which is a test accelerator to establish accelerator technologies for GeV-class synchrotron light source based on ERL (Energy Recovery Linac), Gun Test Facility is constructing in KEK, AR south experimental hall. The Gun Test Facility consists of a 500 kV gun construction area, a laser system area and a gun test beamline with...
A non-destructive testing method on Glass Fibre Reinforced Polymer (GFRP) after high velocity impact event using single stage gas gun (SSGG) is presented. Specimens of Ctype and E-type fibreglass reinforcement, which were fabricated with 6mm, 8mm, 10mm and 12mm thicknesses and size 100 mm x 100 mm, were subjected to a high velocity impact with three types of bullets: conical, hemispherical and ...
Thermal barrier coating are perceived as an enabling technology to increase the performance of, improve efficiency within, and lower the emissions from, modern gas turbines. To fully utilise this capability one has to be able to accurately predict the life of these coatings under conditions relevant to gas turbine service. This paper addresses the failure of TBC systems as a result of erosion a...
Abstract Most modern tank guns are high bore pressure smooth-bore that often use High Explosive Antiarmor (HEAA) projectile in combat. This paper focuses on the coupled smoothbore gun- HEAA system, and analyses ramming-band engraving process when a fires projectile. First, finite element mesh model of coupling dynamics large-calibre gun barrel was established, band discretized by using Smoothed...
Charged particulate spray systems are common in many industrial and manufacturing processes. Using externally applied electromagnetic fields – the dynamics of these particulate sprays can be altered to achieve improved functionality and access to spray-sites that are hard to reach. With such an alteration the spray-particulate dynamics can become non-intuitive – thereby motivating a physically ...
Marine seismic surveys are used to explore for sub-seafloor oil and gas deposits. These surveys are conducted using air guns, which release compressed air to create intense sound impulses, which are repeated around every 8-12 seconds and can travel large distances in the water column. Considering the ubiquitous worldwide distribution of seismic surveys, the potential impact of exposure on marin...
Helios Gene Gun-mediated transfection is a biolistic method for mechanical delivery of exogenous DNA into cells in vitro or in vivo. The technique is based on bombardment of a targeted cellular surface by micron- or submicron-sized DNA-coated gold particles that are accelerated by a pressure pulse of compressed helium gas. The main advantage of Helios Gene Gun-mediated transfections is that it ...
