The National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory (BNL) is considering an upgrade based on the Photoinjected Energy Recovering Linac (PERL). The various injector schemes for this machine are being extensively investigated at BNL. One of the possible options is photocathode DC gun. The schematic layout of a PERL DC gun based injector and its preliminary beam dynamics...

Laser accelerators offer the promise of producing attosecond electron bunches from a compact accelerator. Electron source requirements for laser accelerators are challenging in several respects, but are achievable. We discuss these requirements, and propose an injector design. Simulation and design work for essential components for a laser accelerator electron source suitable for a high energy ...

The NSLS-II Injector System Diagnostics will provide instrumentation in the linac, Booster, Transfer Lines and Beam Dumps for measuring key beam parameters. These instruments will be adequate for staged commissioning of NSLS-II injectors, and will allow sufficient beam diagnostics for tune-up and top-up operations. This paper summarizes the status of the NSLS-II injector system diagnostics, foc...

Background Barriers to administering epinephrine auto injectors include failure to recognize signs and symptoms of anaphylaxis, administering oral antihistamines or asthma inhalers due to lack of education, failing to administer epinephrine correctly, fear of giving a needle, auto injector misplaced, and past experiences with spontaneous recovery. The aim of this study is to assess the impact o...

The Main Injector Neutrino Oscillation search (MINOS) uses two detectors separated by 735 km to measure a beam of neutrinos created by the Neutrinos at the Main Injector (NuMI) facility at Fermi National Accelerator Laboratory. The experiment has recently reported an observation [1] of νμ disappearance consistent with neutrino oscillations. We describe the manner in which the experiment’s resul...

We present the current development of an injector for a high-contrast, ultrashort laser system devoted to relativistic laser-plasma interaction in the few-cycle regime. The front-end is based on CEP-stabilized Ti:Sa CPA followed by XPW filter designed at the mJ level for temporal cleaning and shortening. Accurate characterization highlights the fidelity of the proposed injector. Measured CEP dr...

At Peking University (PKU) a new helium injector for coupled radio frequency quadrupole(RFQ) and separated function radio frequency quadrupole(SFRFQ) within one cavity, so called as coupled RFQ & SFRFQ, was designed recently[1]. It will provide a 30keV 10mA He beam whose emittance is less than 0.15 π.mm.mrad for the accelerator. It is a combination of a 2.45GHz PKU permanent magnet electron cyc...

Results Adrenaline auto-injector was prescribed in 258 children (66% boys and 34% girls). In 120 of them adrenaline auto-injector was prescribed de novo. 2% of them were babies, 31% 1 to 5 years old, 52% 6 to 14 years old and 15% 15 to 18 years old. In 66% adrenaline auto-injector was prescribed because of anaphylaxis, in 27% because of urticaria or/and angioedema and in 7% because of other rea...

OBJECTIVE To compare the incidence of contrast-induced nephropathy (CIN) and vascular complications in patients undergoing cardiac catheterization using traditional manual contrast injection techniques with those in which an automated contrast injector device was used. BACKGROUND It has been suggested that use of automated contrast injectors in coronary interventions could reduce complication...

A new parameter optimization of the LCLS photo-injector beamline minimizing the transverse emittance has been established for operating the gun at 120MV/m. The design goals of the LCLS photo-injector beamline are to provide a 150 MeV, 10ps FWHM, 1nC bunch at 120Hz with less than 1.2 mm.mrad for the projected emittance and less than 1 mm.mrad for the slice emittance for 80 slices out of 100. The...
