Title:
MULTI PURPOSE COMPACT APPARATUS FOR THE GENERATION OF HIGH-FLUX OF NEUTRONS, PARTICULARLY FOR INTRAOPERATIVE RADIOTHERAPY
Document Type and Number:
WIPO Patent Application WO/2023/281539
Kind Code:
A8
Abstract:
An apparatus (10, 100) for generating a high-flux of neutrons comprising a neutron generator (20, 120) which comprises an emission window (21, 121) and it is configured to emit, from said emission window (21, 121), a flow of neutrons (99), said neutron generator (20, 120) comprising a deuterium ion source chamber (40, 140) wherein positive deuterium ions (D+) or negative deuterium ions (D-) are generated, characterized in that said deuterium ions source chamber (40, 140) is provided with at least one exit electrode (50, 150) that is provided with at least one opening (51, 151) for the outward passage of at least some of said deuterium ions (D+, D-) from said deuterium ion source chamber (40, 140) in an axial direction (Y) towards said emission window (21, 121) through an acceleration tunnel (51,151); wherein said neutron generator (20, 120) comprises a titanium target (14, 114) that is arranged at one end of said acceleration tunnel (51, 151), before said emission window (21, 121), and that is connected to a voltage generator (AV+, AV-) so as to be biased, said titanium target (14, 114) being configured to be struck by the deuterium ions (D+, D-) emitted from said deuterium ion source chamber (40, 140) and consequently to emit neutrons (99) from said emission window (21, 121); and wherein said acceleration tunnel (51, 151) extends along said axial direction (Y) from said at least one exit electrode (50, 150) to said titanium target (14, 114) and is defined by a lateral wall (27, 127) made of an electrical insulating material.
