The Linac Coherent Light Source (LCLS) is a SASE free electron laser using the last 1/3 of the SLAC two mile linac to produce 1.5 to 15 angstrom x-rays in a 100 meter long undulator for use in a variety of x-ray science experiments. In order to satisfy the demanding electron beam requirements, a new 135 MeV photo-injector will be built in an existing, off-axis vault at the 2/3 point of the main...
This paper reports a label-free biosensor combining microfluidics and optical detection based on a Fabry-Perot refractometer. The device monolithically integrates waveguides coupled to distributed Bragg mirrors and also a hydrodynamic particle injector enabling cells to enter the sensor cavity. Recent developments in sub-populations identification based on volumetric refractive index measuremen...
In this work, result of experimental investigation on interaction of fuel spray generated by a swirled type injector, with air motion in a prototype cylinder are presented. Experiments were carried out by planar imaging and particle image velocimetry (PIV) techniques in order to provide information about the spray structure evolution and instantaneous velocity distribution of air motion and ...
In this work, we evaluate the effect of ferrocene delivery in reactor on growth single-walled carbon nanotubes (SWCNTs) an aerosol CVD utilizing monoxide as a feedstock. For purpose, assess output parameters varying gas flow rate through vapor injector hot zone with other conditions (temperature, total rate, and reactant concentration) being fixed. Our experimental results reveal adjustment inj...
A diagnostic neutral beam system has been developed for the Madison symmetric torus ~MST! reversed-field pinch. The system is primarily used: ~1! for measurement of the majority ion equilibrium and fluctuating velocity and temperature by Rutherford scattering ~RS!; ~2! for measurement of the impurity ion velocity and temperature, both equilibrium and fluctuating, by charge-exchange recombinatio...
A high-pressure (> 3 MPa) on-chip injector has been developed for microchip applications including HPLC. The mechanical injector is implemented using in situ photopolymerization of fluorinated acrylates inside wet-etched silica microchips. The injector allows reproducible injections as small as 180 pL with < 250 ms duration. The injector operated robustly over 60 days and over 1000 injections. ...
This study conducted cold flow experimental research on the influence of mass rate atomization characteristics screw conveyer swirl injectors in an opening environment. The Phase Doppler Particle Analyzer (PDPA) and high-speed photography were utilized to obtain data. results showed that greatly influenced establishment working injectors. design point selection exerted significant range perform...
The Injector 2 at Paul Scherrer Institut (PSI) is a 72 MeV separate sector cyclotron producing a high intensity proton beam up to 3 mA CW, which is subsequently injected to the 590 MeV Ring Cyclotron. The injection energy of the pre-bunched beam is 870 keV at an intensity of 10 to 11 mA. In this paper we describe initial conditions for the Injector 2 to obtain a matched beam with space charge t...
