22 Electrostatic ion accelerator EP87307575.8 1987-08-27 EP0300105A3 1989-08-09 Shefer, Ruth; Klinkowstein,Robert Edward

A high current (0.2 to at least 2 milliamperes), low-energy (2.2 to 4 MV) ion beam is generated and is utilized to produce clinically significant quantities of medical isotopes useful in applications such as positron emission tomography. For a preferred embodiment, a tandem accelerator is utilized. Negative ions (202) generated by a high current negative-ion source (200) are accelerated by an electrostatic accelerator in which the necessary high voltage is produced by a solid state power supply. The accelerated ions then enter a stripping cell (212) which removes electrons from the ions, converting them into positive ions. The positive ions (218) are then accelerated to a target which is preferably at ground potential. For a preferred embodiment, the solid state power supply utilized to develop the required voltages is a cascade rectifier power supply (206) which is coaxial with the accelerator between the ion source (200) and the stripper (212), and is designed to have a voltage gradient which substantially matches the maximum voltage gradient of the accelerator.

CONSTITUTION: An accelerating column 208 is housed within a pressurizing chamber 222, a vacuum pump connected to T-shaped tube fittings 201, 220 provided on both end parts of the pressurizing chamber 222 is sued to produce high vacuum inside the column 208, and an ion beam of 0.2mA accelerated at 1MV is emitted from a power source 200 to a target set to a ground potential through the fitting 201, the column 208 and the fitting 220. On the inlet side of the column 208, the beam passing in the inner part is made into a low-energy negative ion beam by a cascade rectifier circuit 206 enclosing the column 208, and the beam is changed into a positive ion beam 218 by a stripping cell 212 which is enclosed by a high-voltage terminal 210. On the outlet side, it is accelerated by use of an accelerator column 216 and emitted toward the target. A high-pressure insulating gas 204 such as SF6 is sealed in the pressurizing chamber 222.

33 Nuclear decay laser and method US09303480 1999-04-30 US06331774B1 2001-12-18 Henry J. Stern
A nuclear decay laser that produces a stream of nuclear decay particles and/or photons of electromagnetic radiation. The stream of nuclear decay particles and/or photons is produced by subjecting radioactive materials to an external magnetic field which causes the radioactive nuclei to align with and precess around the external magnetic field vector. The precessing radioactive nuclei are then subjected to Radio Frequency (RF) pulses tuned to the Larmor frequency of the precessing nuclei which causes the nuclei to flip out of the plane of the external magnetic field vector into the X-Y plane. A refocusing RF pulse is then applied to the radioactive material which brings all of the magnetic moments of the flipped radioactive nuclei into phase. This can also be achieved with MRI gradient echo technology. When the initial RF pulse is discontinued, the flipped radioactive nuclei undergo T1 or spin-lattice relaxation which occurs when the radioactive nuclei relax back into phase with the external magnetic field vector during the process of T1 relaxation. The radioactive nuclei undergo accelerated coordinated decay with emission of a laser type pulse of electromagnetic radiation or particles according to the decay scheme of the radioactive nucleus. Alternatively, a ray of energy and/or particles is released when radioactive nuclei capable of undergoing fission experience a coordinated, accelerated fission reaction achieved when the refocusing RF pulse or gradient echo brings the radioactive nuclei into a coherent phase. The release of energy and/or particles can be focused and used in medical treatment and imaging, industrial and military applications, and for the production of energy. In addition, these methods of accelerating nuclear decay can be used to treat unwanted radioactive materials to background radiation levels providing for a way of disposing of unwanted nuclear waste.
