In the Budker Institute of Nuclear Physics an accelerator based epithermal neutron source was proposed and designed to the development of the perspective cancer treatment, which is the Boron Neutron Capture Therapy. The source consists of a vacuum-insulated tandem accelerator, which produces a 2MeV proton or deuterium beam, a lithium target in which neutrons are generated in the 7 Li(p, n)7...
The new compact accelerator-based neutron facility AISTANS at the National Institute of Advanced Industrial Science and Technology in Japan was constructed. AISTANS is providing a pulsed neutron beam from a decoupled solid methane moderator from 2020. In this presentation, overview of AISTANS and a recent neutron flux measurement result at AISTANS will be presented.
China Spallation Neutron Source (CSNS) accelerator complex consists of a front end, an 80MeV DTL LINAC, and a 1.6GeV Rapid Cycling Synchrotron (RCS). It is designed with a beam power of 100kW in the first phase and reserves upgrade capability to 500kW in the second phase. CSNS has started user operation at 20kW after the initial beam commissioning in 2018, the beam power is quickly up to 50kW...
The China Spallation Neutron Source (CSNS) is an accelerator-based science facility. CSNS is designed to accelerate proton beam pulses to 1.6 GeV kinetic energy, striking a solid metal target to produce spallation neutrons. CSNS has two major accelerator systems, a linear accelerator (80 MeV Linac) and a 1.6 GeV rapid cycling synchrotron (RCS). The RCS accumulates and accelerates the proton...
An RF driven negative hydrogen source is under development for the upgrade of China Spallation Neutron Source (CSNS), which requires an H$^-$ beam current more than 50 mA, and a duty factor of 1.5%$\sim$2%. The ion source produces an H$^-$ beam of 20 mA without cesium injection. After it is cesiated, about 47 mA H$^-$ beam is extracted. The emittance of the ion beam is measured both with a...
Permanent magnet multipoles can be used for efficient hadron beam transportation. In this presentation, combined quadrupole and octupole magnets for intense ion beam focusing and sextupole magnets for neutron beam focusing and will be presented.
Variable Energy Cyclotron Centre (VECC) is a R&D unit of the Department of Atomic Energy, Government of India. This Centre is dedicated to carry out frontier research and development in the fields of Accelerator Science & Technology, Nuclear Science (Theoretical and Experimental), Material Science, Computer Science & Technology and in other relevant areas.
VECC has been delivering proton,...
An accelerator based neutron source is in operating at the BINP for the development of Boron Neutron Capture Therapy and other applications. Phase space of proton beam was measured using a cooled diaphragm and a wire scanner. The measured phase space and the calculated invariant normalized emittances make it possible to conclude that the proton beam can be transported to an adjacent...
In the Budker Institute of Nuclear Physics an accelerator based epithermal neutron source was proposed and designed [1] to the development of the perspective cancer treatment, which is the Boron Neutron Capture Therapy. The principal unit of the facility is the neutron producing target. The target was irradiated by the proton beam with various energy values from dozens of keV to 2 MeV....
A high-intensity proton accelerator facility requires a high current pulsed negative hydrogen ion source. A Cs-free, negative hydrogen ion source has been developed using inductively coupled discharge technique in pulsed mode by 2 MHz RF external antenna. The RF power coupling to the plasma is enhanced by introducing C-shaped ferrite core around the RF antenna. No external multi-cusp magnetic...
To achieve high intensity, high power or high luminosity, next-generation hadron accelerators like HIAF (High Intensity heavy ion Facility) and EicC (Electron ion collider in China) employ a lot of entirely new beam dynamics and new technology. The development of a simulation code CISP (Simulation Platform for Collective Instabilities) and a control system PACS (Physics-oriented Accelerator...
