At National Institute of Radiological Sciences (NIRS), more than 6500 patients have been successfully treated by carbon-ion beams since 1994. The successful results of treatments have led us to construct a new treatment facility equipped with three-dimensional pencil beam scanning irradiation system. The commissioning of NIRS fast scanning system installed into the new facility was started in S...

The LCLS hard x-ray Free Electron Laser at SLAC reported first lasing in April of 2009. Since then two successful user runs have been completed at the two soft x-ray stations. The first hard x-ray station has started commissioning in July of 2010. Beam diagnostics play an essential role for tuning the machine and delivering the requested beam properties to the users. An overview of the LCLS pho...

The Linac Coherent Light Source (LCLS) is a SASE xray Free-Electron Laser (FEL) project presently under construction at SLAC [1]. The injector section, from drive-laser and RF photocathode gun through first bunch compressor chicane, was installed in fall 2006. Initial system commissioning with an electron beam has recently been completed. The second phase of construction, including second bunch...

TerraSAR-X is a versatile X-Band SAR satellite operating in Stripmap, Spotlight and ScanSAR modes with selectable or dual polarisation. Additionally, experimental modes are possible, like wide bandwidth operation providing even higher resolution, or a left-looking mode. Consequently, cost and time effective concepts for external calibration are mandatory because of the large number of modes and...

In this paper new and innovative techniques during the commissioning phase of TanDEM-X will be presented that are firstly demonstrated on a satellite platform. The focus is on the secondary goals of TanDEM-X that are assigned for the third year of the mission time life due to the tight schedule for the acquisition of the highly accurate global digital elevation model. Therefore, a variety of sc...

The Duke storage ring is a dedicated facility for the UV-VUV FEL operation. The low level computer control system for the Duke storage ring is developed using EPICS. The control hardware employs several different architectures including CAMAC, GPIB, Allen Bradley, and VME. The high level control is implemented in Tcl-Tk scripts running on SPARCstations. TclTk provides the global control capabil...

In a synchrotron such as JHF 3GeV proton synchrotron (PS) and 50GeV PS, choice of an operating point in tune space depends mostly high intensity behavior of a proton beam, not by error fields of magnet manufacturing. Taking that into account, we have started a dry run of optimisation of an operating point, namely simulation of tune survey with space charge effects. The idea is to simulate the e...

Beam commissioning in the KEK Digital Accelerator, which is a small scale induction synchrotron (IS), has been conducted since the middle of 2011. Longitudinal beam motion in the induction synchrotron, utilizing induction cells (IC) for acceleration and confinement, is characterized as barrier bucket acceleration. A tracking code has been developed to understand the longitudinal motion affected...

This project covers simulations of main beam transport in linear colliders, with an emphasis on integrated damping ring to IP simulations; studies of the sources and transport of beam halo from its origin to the IP; Spin polarization transport from the damping ring to the IP; implementation of modeling tools as a diagnostic for addressing commissioning and operational issues. Each of these topi...

An international network of laser-interferometric gravitational wave detectors is nearing the end of the main commissioning phase and will soon enter into an extended observational period, collecting data for a duration of order one year. This article outlines the construction, design and commissioning of the GEO 600 gravitational wave observatory. GEO 600 is a laserinterferometric gravitationa...
