The first ridge side extends generally upward from the interior portion. The ridge top extends from the first ridge side and is generally parallel to the interior portion. The second ridge side extends generally downward from the ridge top. The second ridge side includes a top section and a bottom section. A thickness of the bottom section is smaller than a thickness of the top section. The bottom section includes at least one fixed tab and at least one tear band. The at least one fixed tab is separated from the at least one tear band by at least one vertical membrane.

International Classification:

A61N 5/10
G21G 4/02

Abstract:

A Boron neutron cancer treatment system has a secondary moderator having a central treatment chamber for a subject, and eight substantially identical neutron generators, each comprising a pre-moderator block. The eight neutron generators are positioned around the secondary moderator with the axis of each acceleration chamber passing through the center of the treatment chamber, and with the angled sides of the neutron generators fully adjacent.

International Classification:

A61N 5/10
G21G 4/02

Abstract:

A Boron neutron cancer treatment system has a secondary moderator having a central treatment chamber, and several generators, each comprising a pre-moderator block, an acceleration chamber, a vacuum pump engaging the acceleration chamber at a right angle, a plasma ion chamber opening into the acceleration chamber, a gas source providing deuterium gas to the plasma ion chamber, a microwave energy source ionizing the gas in the plasma ion chamber, a cylindrical primary isolation well extending into the pre-moderator block, a secondary isolation well surrounding the primary isolation well, and a water-cooled titanium target disk at a lower extremity of the isolation well. The neutron generators are positioned around the secondary moderator with the axis of each acceleration chamber passing through the center of the treatment chamber, and with the angled sides of the neutron generators fully adjacent.

International Classification:

A61N 5/10
G21G 4/02

Abstract:

A neutron generator has a pre-moderator block of moderating material, an acceleration chamber, a vacuum pump evacuating the acceleration chamber to a moderately high vacuum, a plasma ion chamber opening into the acceleration chamber through an ion extraction iris, a gas source providing deuterium gas to the plasma ion chamber, a microwave energy source ionizing the gas in the plasma ion chamber, a primary and a secondary isolation well extending into the pre-moderator block, a water-cooled titanium target disk positioned at a lower extremity of the primary isolation well, the target disk biased to a substantial negative DC voltage, and electrically grounded metal cladding covering surfaces of the pre-moderator block. Ions extracted through the ion extraction iris are accelerated to bombard the titanium target producing energetic neutrons that pass through and are moderated by the pre-moderator block.
