surface does not exceed 10 mSv. This paper describes the The Stanford Synchrotron Radiation Laboratory (SSRL) Inshielding and radiation protection at the injector. jector is comprised of a linear accelerator (linac) capable of INTRODUCTION energies 5 150 MeV, a 3 GeV booster synchrotron, and a beam line to transport the electrons into the storage ring Figure 1 shows a layout of the injector. Th...

The results of detailed numerical simulation of the flow in an injector including electrohydrodynamic interaction in sharply inhomogeneous electric field formed by electrode system closed to the needle-plane type are presented. The aim of the simulation is to estimate the charge rate flow at the fuel injector outlet. The results were obtained using the open-source package OpenFOAM in which the ...

Protection of personal data is essential for customer acceptance. Even though existing privacy policies can describe how data shall be handled, privacy enforcement remains a challenge. Especially for existing applications, it is unclear how one can effectively ensure correct data handling without completely redesigning the applications. In this paper we introduce Privacy Injector, which allows ...

OBJECTIVE To compare injector-based contrast agent (CA) administration with hand injection in magnetic resonance angiography (MRA). METHODS Gadobutrol was administered in 6 minipigs with 3 protocols: (a) hand injection (one senior technician), (b) hand injection (6 less-experienced technicians), and (c) power injector administration. The arterial bolus shape was quantified by test bolus measu...

The 50 TeV very large hadron colliders studied at the 1996 Snowmass workshop were taken to have an injection energy of 3 TeV. As the injection energy increases, the cost and complexity of the final injector increases, while that of the collider decreases. In this paper, we would like to consider the extreme case of a full energy injector. Presumably, this produces the maximum benefit, in terms ...

A possibility to develop a compact linac-based Infrared free-electron laser (IR FEL) facility has been studied at Chiang Mai University (CMU) in Thailand. Characteristics of the emitted FEL light and reliability in operation of the FEL system are determined by the properties of the electron injector, the undulator, and the optical cavity. The proposed injector system for the future IR FEL is ba...

Abstract—A fuel injection system to drive a common rail injector was developed using an 8-bit microprocessor. Common rail pressure control and injector driving systems are both essential for injecting fuel at a controlled pressure. With various duty ratios of the square wave generated from the CCP (capture compare PWM) pin of a microprocessor to the common rail pressure controller, the common r...

On the Madison Symmetric Torus magnetic fusion plasma experiment, frozen pellet injection is an established method of depositing deuterium fuel into the core of the plasma. To freeze deuterium gas into pellets, the injector is cooled to 10 K with a cryogenic helium refrigerator. To exhaust residual frozen deuterium following injection of each pellet, the injector is warmed by resistive heating ...
