Liquid Li based neutron source for BNCT and science application

Present status of accelerator-based BNCT: Focus on developments in Argentina

“…The UK and Russian machines are electrostatic (a dynamitron and a vacuum insulated tandem respectively) and are operating on still too low intensity beams for a therapeutic facility (around 1 to 2 mA on solid Li targets) and would need an upgrade in this respect. There are also two projects starting in Japan (Osaka and Nagoya) based on the dynamitron (Horiike et al, 2014;Tsuchida et al, 2014). The machine in Israel is an RFQ-DTL (Radio Frequency Quadrupole-Drift Tube LINAC) already operating on a liquid Li target with still modest currents of about 1.3 mA.…”

Mock-up experiment at Birmingham University for BNCT project of Osaka University – Neutron flux measurement with gold foil

“…In Osaka University, development of a new accelerator-based neutron source (ABNS) for Boron Neutron Capture Therapy (BNCT) is now in progress under the collaboration with Sumitomo Corporation and Mitsubishi Heavy Industries Mechatronics Systems, Ltd. (Horiike et al, 2014). The ABNS employs an electrostatic accelerator which produces low energy neutrons of 10 13 n/sec having several hundred keV via p-Li ( 7 Li(p,n) 7 Be) reaction (Liskien and Paulsen, 1975).…”

Performance of a liquid Ga target for Laser Ion Source

“…For example, liquid metal droplets [18][19][20] and liquid on a rotating disk target [21] were used for the generation of extreme ultraviolet (EUV) light sources, showing good shot-to-shot stability, remarkable for LIS application as well. In addition to this method, a thin film of vertically flowing liquid lithium jet has been also studied as a charge stripper of ion beams [22] and as a neutron production target [23,24]. Despite not being originally intended for laser ablation application, the precise controlled surface flatness represents an attractive feature for LIS.…”
