| 111 | Plural foils shaping intensity profile of ion beams | US09707950 | 2000-11-08 | US06462348B1 | 2002-10-08 | William Z. Gelbart |
| The invention presents an approach that uses plural separated foils to shape an ion beam so that the intensity density of hot spots in the ion beam is lowered. More particularly, plural foils are placed in close proximity to each other, wherein at least one foil intercepts a portion of the beam to strip a charge from ions in different portions of the beam at different times, and thus, shape the ion beam. At a basic level, the inventive approach places plural foils so that the distance between planes of successive foils is a fraction of the radius of curvature of the beam's cyclotron orbit. | ||||||

| 113 | Charge-exchange device | US162066 | 1998-09-29 | US6137246A | 2000-10-24 | Yasuo Suzuki |
| A charge-exchange device is disclosed which is able to considerably reduce, without the use of foils, radio activation caused by a beam deflection angle and, which also implements a further efficiency and reduction of a laser output. The charge-exchange device is provided with an undulator and an optical resonator. The undulator magnetic field which has been generated by the undulator generates the Lorentz electric field by interaction with the relativistic velocity of H.sup.0 neutral beam being injected. The optical resonator amplifies the photon density of the laser beam and causes it to collide against the injected H.sup.0 neutral beam, thereby resonantly exciting the H.sup.0 beam to the principal quantum number of 4. The H.sup.0 beam which has been resonantly excited or excited by the relativistic Doppler effect in the undulator magnetic field is ionized to H.sup.+ ion by the Lorentz electric field. | ||||||

| An etching system contains a plasma chamber, a charge exchange chamber and a processing chamber. The charge exchange chamber and the processing chamber are partitioned with a porous plate provided with a number of fine linear microchannel holes. Positive ions generated by the plasma chamber are accelerated by an accelerating electrode in the charge exchange chamber, charge-exchanged and introduced as neutral particles through the microchannel holes into the processing chamber. Neutral particles are vertically entered into an object to be processed as neutral particle beams that are completely aligned by the microchannel holes. An object with a large surface area can be etched with high accuracy by making the porous plate a size which corresponds to the object. Thus, plasma processing with only neutral particles is carried out with high accuracy even when the surface area of the object is large. | ||||||

| 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 generated by a high current negative-ion source 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 which removes electrons from the ions, converting them into positive ions. The positive ions 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 which is coaxial with the accelerator between the ion source and the stripper, and is designed to have a voltage gradient which substantially matches the maximum voltage gradient of the accelerator. | ||||||
