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 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 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 کاملA practical target system for accelerator-based BNCT which may effectively double the dose rate.
A dose-limiting component of a proton accelerator-based source of epithermal neutrons is the neutron production target. Possible targets are lithium, producing high yield but having low melting point and thermal conductivity, and beryllium, presenting less engineering problems but a much smaller neutron yield. We propose that a hybrid Be-Li target would provide the best of both worlds, with the...
