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...

A conceptual design of the input coupler for superconducting injector cavities of Cornell ERL project is presented. The injector cavities are two-cell structures operating at 1300 MHz in CW mode. The coupler has a symmetric design to accommodate requirements for small transverse kick, high RF power delivery to the cavity, and high coupling value. It consists of two identical antenna type couple...

The Advanced Photon Source (APS) primary and backup injectors consist of two thermionic-cathode rf guns. These guns are being upgraded to provide improved performance, to improve ease of maintenance, and to reduce downtime required for repair or replacement of a failed injector. As part of the process, an injector test stand is being prepared. This stand is effectively independent of the APS li...

This paper describes a scheme to control the intrapulse energy variations of long pulse bursts of an induction linac. Analog control over the electron beam injector current is exercised in such a way that accelerator beam load variations compensate for thermal impedance variations of the accelerator cell ferrites. Circuit topology and test data are presented. The circuit uses 64 planar triodes ...

A new acceleration structure named as coupled radio frequency quadrupole and separated function radio frequency quadrupole cavity (Coupled RFQ & SFRFQ) is under design at Peking University (PKU). A pulsed or CW He beam injector will be needed to transport 30 keV 20 mA He beam and normalized rms emittance less than 0.15 pi.mm.mrad for this composited type cavity. For pulsed mode, the factor is 1...

The single spike operation regime has been analyzed in the case of the SPARC injector and freeelectron-laser. Four different beams at 50 pC are studied, with different production condition and performance. SINGLE SPIKE OPERATION IN SPARC SASE-FEL I. Boscolo, F.Castelli, S. Cialdi, V.

MODELING OF THERMAL NON-EQUILIBRIUM IN SUPERHEATED INJECTOR FLOWS

The technique of Hadamard transform was successfully coupled with GC/nonresonant multiphoton ionization/TOFMS, for the first time. 1,4-Dichlorobenzene and the fourth harmonic generation (266 nm) of a Nd:YAG laser were employed as a model sample and an ionization laser, respectively. A Hadamard-injector coupled with a capillary-based supersonic jet nozzle (capillary-injector) was also developed ...
