摘要： PURPOSE:To improve the gas efficiency of a neutralized cell by using a unit neutralized cell assembly having a cross sectional area corresponding to the unit electrode area of an ion source for the neutralized cell. CONSTITUTION:A unit neutralized cell 20 is installed at the position corresponding to the unit electrode of a negative ion source, and eight unit neutralized cells 20 are collected to constitute a neutralized cell 1. The cell 20 has a cross sectional area a2 somewhat larger than the area a1 of the unit electrode in view of the region for beam divergence and plasma confinement. The gas efficiency is sharply improved when multiple cells each having a small cross sectional area are collected to provide the same cross sectional area in total, thus the gas efficiency is improved even when the cross sectional area 8a2 of the cell 1 constituted of eight unit neutralized cells 20 is made equal to the cross sectional area A1 of one neutralized cell. The void area of an electrode section can be omitted, thus the area 8a2 can be made smaller than the area A1, and the gas efficiency is further improved.

摘要： PURPOSE:To enable the direct power reception from a commercial power system by connecting a variable resistor in parallel with electric facilities when the electric facilities, which receive power supply from the power system, cause sharp power fluctuation. CONSTITUTION:When the electric facilities receiving power supply from a power system 12 produce the power fluctuation in the reductive detection being sharp enough to fluctuate the voltage, etc., of this power system 12, switches 28a-28c are actuated to connect variable resistors 26a-26c in parallel with the electric facilities, and the amounts of power fluctuation are consumed once with these variable resistors 26a-26c. Next, the resistance values of the variable resistors 26a-26c are increased for a specified period, so that the power from the power system 12 to the power system suppressor 24 side may fluctuate slowly, so as to decrease the consumption power. And when the consumption power of the variable resistors 26a-26c has become small, the variable resistors 26a-26c are separated from the power system 12 by the switches 28a-28c.

摘要： PROBLEM TO BE SOLVED: To obtain a neutral-particle impingement apparatus in which it is not required to replace a radiated component with an unradiated component and which reduces costs required for a maintenance operation by a method wherein a specific neutron shielding body is installed between a magnetic sheild and a vacuum container. SOLUTION: A neutralization cell 103, a beam damp 104, vacuum containers 113, 114 and a cryopump 106 are made of a low-activation material such as an aluminum alloy or the like. In addition, a neutron shielding body 121 which is constituted of polyethylene or of a polyethylene compound is installed between the vacuum containers 113, 114 and a magnetic shield 107. It is possible to prevent the magnetic shield 107 from being activated by the neutron shielding body 121, it is possible to reduce a dose equivalent rate inside a neutral-particle impingement apparatus, and a direct operation by a human being can be performed. Thereby, in every maintenance operation, it is not required to replace all radiated components with unradiated components so as to reduce the dose equivalent rate inside the neutral-particle impingement apparatus, individual components can be replaced individually, and the costs of the maintenance operation can be reduced.

摘要： PURPOSE:To produce a charged particle beam carrying a large current, good in the converging characteristic, and equipped with a high brightness by arranging a plurality of magnets around electrode hole provided in each accelerating electrode, and generating a quadripolar magnetic field within this electrode hole. CONSTITUTION:In an electrostatic acceleration system 2 to accelerate a charged particle beam by permitting it to pass through a single electrode hole 1, magnets 5 to generate a pair of quadripolar magnetic fields 4a, 4b are installed above and below and on the left and right of each of accelerating electrodes 3 in multi-stage arrangement. When a charged particle beam is incident to the downstream quadripolar magnetic field 4A, the beam has a larger energy than when situated further downstream, and therefore, a charged particle beam converged both in the horizontal and vertical directions is obtained by giving the upstream quaripolar magnetic field 4B a greater intensity than the other 4A.

摘要： PURPOSE:To facilitate alignment of the axis of the captioned electrode, by supporting the electrode to a holding frame at plural positions through a spring by means of an adjusting screw, and further pressing the wall face of the holding frame by means of the adjusting screw which is screwed and connected to the electrode placed at right angles to said adjusting screw. CONSTITUTION:A reference electrode 23 is disposed through a spacer 26 in a holding frame 25 which supports a perforated electrode 24, and moreover a holding frame 21 which supports a perforated electrode 22 is disposed through the spacer 26 in order to form a drawer-type electrode for ion source. Also, an adjusting screw 33 is inserted into each of through holes 28 uniformly distributed on its flange 27 through a coned-disc screw 32, and said electrode 22 is screwed into a screw 29 of the holding frame 21 and supported, and is also supported by applying plural adjusting screws 34 to the wall face of the holding frame 21. Consequently, the gap toward the reference electrode 23 can be made constant by adjusting the screw 33, next, the positioning of the hole 35 of said electrode 22 can be performed by means of a screw 34, and thereby the adjusting time can greatly be shortened.

摘要： PURPOSE: To use a degree of vacuum in a limited range determined by a thermal load of beam damps and to make a neutralization efficiency maximum by changing the degree of vacuum in a neutralizing cell in correspondence to an ion source accelerating voltage so that the maximum neutralization efficiency be obtained. CONSTITUTION: By changing a degree of vacuum in a neutralizing cell in correspondence to an ion source accelerating voltage so that a maximum neutralization efficiency be obtained, a beam can be cast with a neutralization efficiency made maximum at all times even when the accelerating voltage is changed. By making the degree of vacuum in the neutralizing cell 2 be within a range determined by holding down a thermal load on a positive ion beam damp 4 and a negative ion beam damp 5 to be critical values or below, in correspondence to the ion source accelerating voltage, the thermal load on the positive ion beam damp 4 and the negative ion beam damp 5 is limited and thereby burning of the beam damps can be prevented.

摘要： PURPOSE:To automate the measurement of four-dimensional emittance and to enhance measuring accuracy by integrating a pinhole, a two-dimensional image sensor detecting the intensity distribution of a particle beam and a photoelectric converter. CONSTITUTION:The intensity distribution image formed by this measuring apparatus becomes the signal of the image output to a television screen by a photoelectric converter such as a CDD camera to be stored in a digital video memory 7. A computer 8 calculates the projection angle of the image of a two-dimensional image sensor 2 or the intensity distribution of a particle beam on the basis of the memory of the digital video memory 7. In this case, a pinhole 2 is set to the arbitray position within the cross-section (x-y cross-section) of a particle beam B by driving a movable part 5 and, by performing the above mentioned operation, (x', y') with respect to the position of the pinhole 2 or the intensity distribution of the particle beam can be easily calculated.
