When using superconducting (SC) magnets in a gantry for proton therapy, the will benefit from some reduction size and large weight. In this contribution we show an important additional advantage of SC therapy treatments. We present design with bending section achromatic beam optics very momentum acceptance [Formula: see text]15% (corresponding to about text]30% energy domain). Due related acceptance, approximately 70% treatments can be performed without changing magnetic field...
Two 6-t beam dumps, made of a graphite core encapsulated in stainless steel vessel, are used to absorb the energy two Large Hadron Collider (LHC) intense proton beams during operation accelerator. Operational issues started appear 2015 LHC Run 2 (2014-2018) as consequence progressive increase kinetic energy, necessitating technical interventions highly radioactive areas around dumps. Nitrogen gas leaks appeared after energetic impacts and instrumentation measurements indicated an initially...
During the conceptual design of an accelerator or beamline, first-order beam dynamics models are essential for studying properties. However, they can only produce approximate results. commissioning, these results compared to measurements, which will rarely coincide if model does not include relevant physics. It is therefore that this linear extended higher-order effects. In paper, effects particle-matter interaction have been included in transport lines proton therapy facility at Paul...
Charged particle therapy, or so-called hadrontherapy, is developing very rapidly. There large pressure on the scientific community to deliver dedicated accelerators, providing best possible treatment modalities at lowest cost. In this context, Italian research Foundation TERA fast-cycling dubbed `cyclinacs'. These are a combination of cyclotron (accelerating ions fixed initial energy) followed by high gradient linac boosting energy up maximum needed for medical therapy. The powered many...
This paper provides an overview of the worldwide first commissioning a gantry beamline with rotator at MedAustron synchrotron-based proton/ion cancer therapy facility in Wiener Neustadt, Austria. The consists high energy beam transfer (HEBT) line and transport system. It transports from synchrotron to gantry-room isocenter. HEBT entrance, which is coupling point between gantry. one modules, thus it integral part beamline. system used match slowly extracted asymmetric beams rotating In this...
A novel design of a gantry for proton therapy is investigated in which degrader and emittance limiting collimators are mounted on the gantry. Due to interactions protons these components there will be an additional neutron dose at location where patient positioned during therapy. The results numerical study this presented. Neutron prompt position estimated through Monte Carlo simulation using MCNPX 2.7.0 particle transport code. Secondary photon fluxes from distinct beam loss points taken...
At the proton therapy facility PROSCAN of Paul Scherrer Institute energy modulation cyclotron generated beam is performed via material insertion into trajectory. The spectrum particles propagating forwards after such procedure has been simulated and measured. current paper summarizes results these simulations measurements illustrates their significance for future developments a gantry at Institute.
Rotating gantries are commonly used in ion-therapy facilities to assist and support optimizing the dose distribution delivered patient. They installed at end of beamlines rotated mechanically treatment room. In synchrotron-based facilities, must be able transport slowly extracted beams with essentially different emittance patterns two transverse planes. Such will referred as asymmetric beams. A special device called rotator has been proposed a possible solution. The worldwide first beamline...
Abstract MedAustron is a synchrotron-based Particle Therapy Accelerator located in lower Austria which delivers clinical proton and carbon beams the range of 62-252.7 MeV/u 120-400 respectively two treatment rooms. A Gantry was recently commissioned third room fourth experimental beamline dedicated to non-clinical research activities. Within latter, injector commissioning has started for He 2 + beam generation. The long-term goal use helium cancer due its favourable physical biological...
New collimators are being produced at CERN in the framework of a large particle accelerator upgrade project to protect beam lines against stray particles. Their movable jaws hold low density absorbers with tight geometric requirements, while able withstand direct proton impacts. Such events induce considerable thermo-mechanical loads, leading complex structural responses, which make numerical analysis challenging. Hence, an experiment has been developed validate jaw design under...
After the High Luminosity (HL-LHC) upgrade, LHC will be exposed to a higher risk of magnet quenches during periods short beam lifetime. Collimators in extraction region (IR6) assure protection magnets against asynchronous dumps, but they also intercept fraction halo leaking from betatron cleaning insertion. In this paper, we assess quenching nearby quadrupoles lifetime drops. particular, present an empirical analysis losses IR6 using Run 2 (2015-2018) loss monitor measurements. Based on...
