Grid polarisers 3D-printed out of commercial acrilic resin were tested for the polariser function and showed spectral regions where dichroic ratio implying importance molecular and/or stress induced anisotropy. Metal-coated THz optical elements can find a range applications in intensity polarization control IR-THz beams. The used 3D printing method allows fabrication an arbitrary high aspect grid polarisers. Polarization analysis synchrotron radiation was carried with standard stretched...
FLASH radiotherapy, which refers to the delivery of radiation at ultra-high dose-rates (UHDRs), has been demonstrated with various forms and is subject intense research development recently, including use very high-energy electrons (VHEEs) treat deep-seated tumors. Delivering radiotherapy in a clinical setting expected place high demands on real-time quality assurance dosimetry systems. Furthermore, electron currently requires transformation existing non-medical accelerators into...
Investigations into producing an electron beam with ultralow vertical emittance have been conducted using the Australian Synchrotron 3 GeV storage ring. A method of tuning coupling (${ϵ}_{y}/{ϵ}_{x}$) has developed a machine model calibrated through linear optics from closed orbits method. Direct measurements not possible due to diagnostic limitations, however two independent indirect both indicate 1.2--1.3 pm rad (${ϵ}_{y}/{ϵ}_{x}=0.01%$). Other support validity these results. This result...
RHIC EBIS will be used for producing multicharged ions from helium to uranium using primary various external ion sources. The is followed by an RFQ and short linac, forming the new preinjector which produce beams physics at NASA Space Radiation Laboratory, design of based on BNL Test EBIS, was a successful 10A electron current prototype. Improvements have been made in increase capacity trap, repetition frequency operation, current, acceptance injected ions, improve vacuum conditions...
The Pulsed Energetic Electrons for Research (PEER) beamline at the ANSTO Australian Synchrotron comprises a 100 MeV linac injector that is currently being developed ultra-high dose-rate, very high-energy electron radiotherapy research. Previously, dosimetry studies discovered lack of reliable charge measurement to in-air end station, though no change in response was recorded fast current transformer measurements, only available diagnostic device measuring charge. This work describes process...
This paper presents measurements of the GeV-scale electron beam energy for storage rings at synchrotron light source facilities Australian Synchrotron (AS) and SPEAR3 SLAC. Resonant spin depolarization was employed in measurement, since it is presently highest precision technique an uncertainty order ${10}^{\ensuremath{-}6}$ achieved AS. Using resonant technique, measured various rf frequencies to measure linear momentum compaction factor. factor used evaluate models trajectory through...
The technique of frequency map analysis has been applied to study the transverse dynamic aperture Australian Synchrotron Storage Ring. results have used set strengths sextupoles optimise aperture. effects allowed harmonics in quadrupoles and dipole edge are discussed.
RHIC electron beam ion source has been commissioned to operate as a versatile on injection facility supplying species from He Au for Booster. Except light gaseous elements EBIS employs several external primary sources. With electrostatic optics fast switching one another can be done pulse mode. The design of an optical structure and the results simulations different are presented. In choice special attention was paid spherical aberrations high-current space charge dominated beams....
Using a vertical undulator, picometer electron beam emittances have been observed at the Australian Synchrotron storage ring. An APPLE-II type undulator was phased to produce horizontal magnetic field, which creates synchrotron radiation field that is very sensitive emittance. The measured ratios of spectral peak heights are evaluated by fitting simulations apparatus. With this apparatus immediately available most existing and positron rings, we find be an appropriate novel emittance diagnostic.
Further reduction of betatron coupling and vertical dispersion in the storage ring Australian Synchrotron Light Source has resulted achievement a beam emittance that is now dominated by intrinsic quantum effects. This paper will detail key elements achieving at limit results achieved.
We present a generalized Gerchberg-Saxton (GS) algorithm for reconstructing (2+1)-dimensional complex scalar wave field which obeys known nonlinear nondissipative parabolic differential equation, given knowledge of the wave-field modulus at three or more values an evolution parameter such as time. This is used to recover function Bose-Einstein condensate (BEC) from simulated data. The Gross-Pitaveskii equation model dynamics BEC, with information being provided by temporal sequence...
A case of arterial occlusion occurred nine years after replantation a thumb. Factors implicated were smoking and repeated blunt trauma to the first web space. The digit was successfully revascularized excision segment thrombosed vein graft.
LOCO has been used during the commissioning of Australian Synchrotron storage ring with a number benefits. The (linear optics from close orbits) method compares model response matrix to real machine matrix. Using this approach we are able adjust match ideal model. Results presented here show that provided high degree control over wide range parameters.
Preliminary plans are presented for a sub-Angstrom wavelength XFEL at the Australian Synchrotron light source site. The design is based around 6 GeV x-band linac from CLIC Project. One of motivationsfor to have an co-located on site with existing storage ring synchrotron source. desire and ability photon science community win beamtime XFELs has lead this study plan future machine in Australia. technology choice also driven by participation collaboration local HEP community.
The X-band FEL collaboration is currently designing an X-ray free-electron laser based on acceleration technology. Due to the higher accelerating gradients achievable with technology, a normal conducting linac can be shorter and therefore potentially cost ecient than what lower frequency structures. This reduction of future facilities addresses growing demand user community for coherent X-rays. consists 12 institutes universitiesthatjointlyworkonthepreparationofdesignreports specific...
The Australian synchrotron's Storage Ring is equipped with a full compliment of 98 Libera electron beam position processors from I-tech (EBPPs) [1]. EBPPs are capable measuring data at turn-by-turn (TBT) rates and have long history buffers. TBT the has been used to determine linear optics storage ring lattice using techniques developed other facilities. This useful complement methods determining such as LOCO. Characteristics current dependence studied during commissioning will also be presented.
