A laser-driven photo-cathode electron gun capable of producing pulsed electron beams of 100 KeV with a duration of 35 ps was constructed as a continuing effort towards a high-brightness superconducting RF injector. Various species of photo-cathodes can be obtained either by ion implantation, CVD or ion enhanced deposition in the preparation chamber attached to the injector. A number of photo-ca...
Two-dimensional simulations of transpiration cooling in a laminar, hypersonic boundary layer were performed using the thermochemical implicit nonequilibrium algorithm (TINA): Navier–Stokes solver. Coolant concentration and heat flux results are compared to data obtained from laminar experiments conducted Oxford High Density Tunnel employing flat-plate geometry at Mach 7. TINA successfully predi...
We present experimental results of transverse electron-focusing measurements performed using n-type GaAs. In the presence of a small transverse magnetic field (B⊥), electrons are focused from the injector to detector leading to focusing peaks periodic in B⊥. We show that the odd-focusing peaks exhibit a split, where each sub-peak represents a population of a particular spin branch emanating fro...
The control system of the 1.5 MeV FEL injector is built on the base of ported EPICS. It uses low-cost hardware: personal computers with the processor Intel x86 and CAMAC equipment produced by our institute. At present time, the distributed control system includes one Pentium at OPerator Interface (OPI) level and two IOC (Input Output Controllers) under supervision of the real time operating sys...
The Photo Injector Test facility at DESY, Zeuthen site (PITZ), develops high brightness electron sources for modern free electron lasers. A continuous experimental optimization of the L-band photo injector for such FEL facilities like FLASH and the European XFEL has been performed for a wide range of electron bunch charges – from 20 pC to 2 nC – yielding very small emittance values for all char...
Results of experimental investigations of using a coil-shaped injector for reducing NOx emissions from a diesel engine are presented. The study involved the effects of coil length and its mixing effectiveness and the development of the injector system for after treatment of diesel exhausts. Results indicate that the coil-shaped injector system with the ratios of length, pitch and wire diameter ...
Mycolic acids were detected in both reference strains and clinical isolates of mycobacteria using gas chromatography of fatty acid methyl esters prepared by acid methanolysis. The methyl esters were extracted with hexane, concentrated, and analyzed with a gas chromatograph by using two different injector temperatures. When the samples were analyzed at high injector temperatures of 300 to 350 de...
Currently there are no FDA-approved DMEK injectors. American surgeons have found many creative off-label methods around this obstacle. Many surgeons use modified intraocular lens injection cartridges for this purpose. The Staar microinjector (Staar Surgical Company, Monrovia, CA) was one of the most common inserters initially used for DMEK in the US (Fig. 131.1B). The Staar injector is an open ...
