For radiation therapy with carbon ion beams, either for the stable isotope (12)C or for the radioactive one (11)C, it has been demonstrated that the beta(+)-activity distribution created or deposited, respectively, within the irradiated volume can be visualized by means of positron emission tomography (PET). The PET images provide valuable information for quality assurance and precision improve...

Particle beams in accelerators are detected through the electromagnetic elds they create. Position and intensity monitors are based on the near eld which stays attached to the charges. A large variety of measurements can be carried out with these devices. The closed orbit is obtained by reading out the position averaged over many turns. Change in the orbit resulting from a controlled de ection ...

We expound in detail the physics reach of an experimental set-up in which the proposed large magnetized iron detector at the India-based Neutrino Observatory (INO) would serve as the far detector for a so-called beta-beam. If this pure νe and/or ν̄e beam is shot from some source location like CERN such that the source-detector distance L ≃ 7500 km, the impact of the CP phase δCP on the oscillati...

A 106.08MHz superconducting quarter wave resonator, based on the bulk niobium technology developed at LNL for low beta heavy ion linacs, has been designed, constructed and tested in a collaboration between INFNLNL and TRIUMF. This superconducting heavy ion linac of ISAC-II, the future extension to the present ISAC radioactive beam facility. sections. Cavity design characteristics and test resul...

INTRODUCTION In this study, we investigated the effects of long-term antihypertensive treatment with calcium channel blockers or beta blockers on the bone mineral density of maxilla, as determined by cone-beam computed tomography (CBCT). MATERIAL AND METHODS This retrospective study was conducted on CBCT images of men older than 55 years who had received different dental indications. Data wer...

After the injection of beam into RHIC the beam energy is ramped from 10.8 GeV/u to 108 GeV/u and the beta function of the interaction points is reduced from 10 meters to 1 meter. The set points for magnet power supplies and RF cavities is changed during such ramps in concert. A system of Wave Form Generators (WFGs), interconnected by a Real Time Data Link (RTDL) and and Event Link is used to co...

The purpose of the final focus system (FFS) of the future linear colliders (ILC and CLIC) is to demagnify the beam to the required size at the interaction point (IP). This can be done in a compact way based on a local chromaticity correction [1]. For an enlarged horizontal beta function at the IP βx*, chromaticity on horizontal plane will be smaller. We get a smaller vertical beam size, at the ...

A standard test field containing numerous strong sources has been observed twice with the ASKAP BETA system, with the third axis of motion – the roll axis – disabled for the second run. These two data sets are subjected to identical calibration and imaging pipelines in order to gauge the e↵ects of the roll axis when observing with a Phased Array Feed. Present beam forming techniques only allow ...

We present a new conceptual and optical design for the Next Linear Collider post-linac collimation system. Energy collimation and passive protection against off-energy beams are achieved in a system with large horizontal dispersion and vertical betatron functions. Betatron collimation is performed in a relatively low-beta (FODO-like) lattice in which only thin spoilers intercept particles near ...
