Patent number: 10737121Abstract: 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.Type: GrantFiled: October 24, 2019Date of Patent: August 11, 2020Assignee: Adelphi Technology, Inc.Inventors: Melvin Arthur Piestrup, Craig Mathew Brown, Allan Xi Chen, Charles Kevin Gary, Yao Zong Guan, Yoshio Horii, Glenn Emerson Jones, Jr., Yuji Kokubo, Naoyuki Yamada, Shotaro Komura
