An Accelerator-based Thermal Neutron Source for Bnct Application
An accelerator-based thermal neutron source, aimed at the Boron Neutron Capture Therapy (BNCT) application on skin melanoma tumour is under construction at the INFN-LNL, in the framework of SPES project. The BNCT facility will exploit the intense proton beam provided by a 5 MeV, 30 mA RFQ that represents the first accelerating step of the SPES exotic nuclei production source. Neutrons are gener...
متن کاملWhat is the best proton energy for accelerator-based BNCT
With a growing interest in the use of accelerator-based epithermal neutron sources for BNCT programs, in particular those based upon the Li(p ,n)Be reaction, there is a need to address the question of ‘‘what is the best proton energy to use?’’ This paper considers this question by using radiation transport calculations to investigate a range of proton energies from 2.15 to 3.5 MeV and a range o...
متن کاملHigh-power Lithium Target for Accelerator-based Bnct
A water-cooled conical target for producing neutrons via the Li(p,n)Be reaction at 2.5 MeV is under development at Linac Systems. The target is intended to accept an expanded 50-kW beam from an rf linac, and is predicted to meet the intensity requirements for practical accelerator-based boron neutron capture therapy (BNCT) in concert with Linac Systems’ CW RFI linac[1]. Lithium metal targets pr...
متن کاملClinical Requirements and Accelerator Concepts for Bnct
Accelerator-based neutron sources are an attractive alternative to nuclear reactors for providing epithermal neutron beams for Boron Neutron Capture Therapy. Based on clinical requirements and neutronics modeling the use of proton and deuteron induced reactions in 7Li and 9Be targets has been compared. Excellent epithermal neutron beams can be produced via the 7Li(p,n)7Be reaction at proton ene...
متن کاملOptimization of the photoneutron target geometry for e-accelerator based BNCT
BACKGROUND AND AIM Today, electron accelerators are taken into consideration as photoneutron sources. Therefore, for maximum production of epithermal neutron flux, designing a photoneutron target is of significant importance. In this paper, the effect of thickness and geometric shape of a photoneutron target on neutron output were investigated. METHODS In this study, a pencil photon source wi...
