The results of the tandem commissioning as initial high voltage tests and beam injection experiments on BINP proton tandem-accelerator are given. The accelerator is intended to be used in facilities generating resonant gamma rays for explosives detection and epithermal neutrons for boron neutron-capture therapy of brain tumors. A magnetically coupled DC voltage multiplier derived from an indust...

Monte Carlo (MC) methods are increasingly being utilized to support several aspects of commissioning and clinical operation of ion beam therapy facilities. In this contribution two emerging areas of MC applications are outlined. The value of MC modeling to promote accurate treatment planning is addressed via examples of application of the FLUKA code to proton and carbon ion therapy at the Heide...

The KEK 8-GeV electron / 3.5-GeV positron linac has been operated with very different beam specifications for downstream rings, KEKB, PF and PF-AR. For the reliable operation among these beam modes, intelligent beam switching and beam feedback systems have been developed and used since its commissioning. A software panel is used to choose one of four beam modes and a switching sequence is execu...

The driver for Jefferson Lab's kW-level infrared free-electron laser (FEL) is a superconducting, recirculating accelerator that recovers about 75% of the electron-beam power and converts it to radiofrequency power. In achieving first lasing, the accelerator operated "straight-ahead" to deliver 38 MeV, 1.1 mA cw current through the wiggler for lasing at wavelengths in the vicinity of 5 μm. Just ...

We present commissioning and comprehensive evaluation for ArcCHECK as a QA equipment for volumetric-modulated arc therapy (VMAT), using the 6 MV photon beam with and without the flattening filter, and the SNC patient software (version 6.2). In addition to commissioning involving absolute dose calibration, array calibration, and PMMA density verification, ArcCHECK was evaluated for its response ...

In the two years past since 8 RFSC Workshop the major efforts of the SRF group at Cornell University were concentrated on the completion and commissioning of the superconducting RF system for the Cornell Electron Storage Ring (CESR) e+e− collider [1, 2]. Four singlecell niobium higher-order mode (HOM) damped cavities replaced four 5-cell normal conducting RF cavities. The RF system upgrade bega...

PURPOSE Commissioning beam data for proton spot scanning beams are compared for the first two Varian ProBeam sites in the United States, at the Maryland Proton Treatment Center (MPTC) and Scripps Proton Therapy Center (SPTC). In addition, the extent to which beams can be matched between gantry rooms at MPTC is investigated. METHOD Beam data for the two sites were acquired with independent dos...

End Station A Test Beam (ESTB) is a beam line at SLAC using a fraction of the bunches of the 15.0 GeV electron beam from the Linac Coherent Light Source (LCLS), restoring test beam capabilities in the large End Station A (ESA) experimental hall. ESTB provides one of a kind test beam essential for developing accelerator instrumentation and accelerator R&D, performing particle and particle astrop...

Construction began in 1995 on ISAC, a radioactive ion beam (RIB) and accelerator facility at TRIUMF that utilises the ISOL (on-line isotope separation) production method. ISAC includes: a new building, a beam line with adequate shielding to transport up to 100 uA of 500 MeV protons to two target/ion-source stations, remote handling facilities for the targets, a high-resolution mass-separator, l...

The growth rates of the longitudinal higher-order impedance-driven beam modes have greatly increased since the initial PEP-II design and commissioning. This increase is attributed to the addition of 6 1.2MW RF stations with 8 accelerating cavities in the HER and 2 1.2MW RF stations with 4 accelerating cavities in the LER, which allowed operations at twice the design current and almost four time...
