The software of the new control system of the 70GeV accelerator complex is built around the distributed real time DBMS SSUDA with emphasis on control of technological process, not equipment. SSUDA was designed to store current states of dynamic parameters and supports 3-D tables. The tables are distributed around all levels of the CS, including equipment controllers. So, DB access protocols are...

ESSnuSB is a design study for an experiment to measure the CP violation in leptonic sector at second neutrino oscillation maximum using beam driven by uniquely powerful ESS linear accelerator. The reduced impact of systematic errors on sensitivity allows very precise measurement violating parameter. This review describes fundamental advantages maximum, necessary upgrades linac order produce bea...

July 2003 Two-dimensional photonic crystal accelerator structures∗ Benjamin M. Cowan† Stanford Linear Accelerator Center, Stanford University, Stanford, California 94309 Abstract Photonic crystals provide a method of confining a synchronous speed-of-light mode in an all-dielectric structure, likely a necessary feature in any optical accelerator. We explore computationally a class of photonic cr...

In this paper we investigate the interaction between the accelerator muscle (the muscle that powers tongue projection) and the entoglossal process (the tongue's skeletal support) that occurs during tongue projection in chamaeleonid lizards. Previous work has shown that there is a delay of about 185 ms between the onset of accelerator muscle activity and the onset of tongue projection. In conjun...

A time-of-flight mass spectrometer (TOF-MS) developed in our laboratory at Isfahan University of Technology is described here. The TOF-MS instrument uses laser as the ionization source which provides an opportunity to investigate the ions formed in laser ablation or desorption. The TOF-MS has an ionization chamber containing an accelerator and an ion lens to focus the ions into a one meter line...

Several plasma accelerator concepts are reviewed, with emphasis on the Plasma Beat Wave Accelerator (PBWA) and the Plasma Wake Field Accelerator (PWFA). Various accelerator physics issues regarding these schemes are discussed, and numerical examples on laboratory scale experiments are given. The efficiency of plasma accelerators is then revealed with suggestions on improvements. Sources that ca...

Demonstrating the generation of electricity with Accelerator-Driven Subcritical Reactor (ADSR) technology will incur substantial financial risk both from traditional reactor construction uncertainties and new technology uncertainties such as the reliability of the accelerator system. The sensitivity of the economic value of ADSRs to the reliability of the accelerator system is assessed. The eco...

This paper reports on MATLAB Channel Access (MCA) Toolbox – MATLAB [1] interface to EPICS Channel Access (CA) client library. We are developing the toolbox for SPEAR3 accelerator controls, but it is of general use for accelerator and experimental physics applications programming. It is packaged as a MATLAB toolbox to allow easy development of complex CA client applications entirely in MATLAB. T...

background: radiation therapy  uses high-energy radiation to kill cancer cells. photoneutron contamination and induced radioactivity of high energy therapeutic photon beams are considered as the main source of occupational exposure to radiation therapists who works with linear accelerators operating above 10 mv. materials and methods: the gamma dose rates were measured after termination of diff...
