摘要： PROBLEM TO BE SOLVED: To uniformly neutralize ion beams with large currents and a large aperture, and to irradiate an object to be worked with the ion beams whose beam dispersion is small. SOLUTION: A microwave neutralizer 14 is arranged in the neighborhood of an accelerating electrode 6 and a decelerating electrode 9 in a working chamber 13 without being turned into a vacuum container, and a multi-ring a cusp magnetic field is formed on the inner peripheral side of an annular electrode 47. When microwaves are introduced through waveguides 24 and 21, the microwaves are absorbed at the position of an electronic cyclotron resonance condition, and a ring-shaped uniform plasma for neutralization is generated on the inner peripheral side of the annular electrode 47. At that time, the annular electrode 47 is maintained as a negative potential to the working chamber 13, and ions are collected from the plasma for neutralization on the annular electrode 47, and electronics in the same quantity as that of the collected ions are supplied to an ion beam 36 so that the neutralization of ion beams 36 can be operated.

摘要： PURPOSE:To stabilize gas laser output without using a special power supply control system by changing laser gas density through laser gas pressure adjustment and by adjusting gain through increase and decrease thereof. CONSTITUTION:When laser beam 21' is detected by a laser power meter 23, detected output is sent to a laser output control device 31 through a laser output signal line 30 in accordance with an arrow 32. Output of a laser beam 21 is calculated by using sensitivity of the laser power meter 23 and laser beam distribution rate of a beam splitter 22, deflection to an objective value is obtained and an instruction for changing a volume of a variable volume gas chamber 4 is sent to a gas chamber volume control device 16 through a gas chamber volume control signal line 29. Therefore, output of the laser beam 21 can be stabilized by performing gain control of laser gas 5 which is laser medium through density adjustment for changing a pressure of the laser gas 5 in the inside of a laser tube 1 by providing physical function as indicated by arrow 33 to the variable volume gas chamber 4 in accordance with an instruction to change a volume of the variable volume gas chamber 4.

摘要： PURPOSE:To accurately control injection amount of halogen gas and to stably operate a laser output for a long time by mounting a second vessel containing a pair of discharge electrodes partly at a laser vessel, and sensing a gas state from voltage, current waveforms between the discharge electrodes. CONSTITUTION:A pair of discharge electrodes 5 are insulated and mounted in a second vessel 3, and a power source 6 is connected to both ends of the electrodes 5. When an ultraviolet ray emitting lamp 11 emits a light 12 between the electrodes 5, the electrodes 5 are preliminarily ionized, triggered to discharge between the electrodes, and charge of a capacitor 8 is fed. The waveforms of a voltage Vp, a current ip between the electrodes are measured by a voltmeter and a current transformer 9. The voltage Vp and the current ip are observed, the value or pattern is compared with a reference density to judge a gas state. Thus, a laser output is stably controlled.

摘要： PURPOSE:To reduce laser output deterioration by forming an output window which is movable to a laser beam and by using the output window avoiding a part whereto impurity is attached. CONSTITUTION:An output window 6 is attached by a window fitting 10 to a window supporting part 9 whose structure enables deformation of a formation bellows, etc. attached to a gas laser container 1 gastightly containing laser gas. In the window 6, impurity produced by laser oscillation attaches only to a transmitting part of a laser beam. Thereby, impurity attaches to the window 6; when lowering of laser light output 8 is observed, the window is moved to the laser beam and a part without attachment of impurity is used. Thereby, output of a laser beam is recovered.
