    • The present invention provides ion implantation equipment in which the beam current in a lower energy region can be increased without making the equipment very large and the production of the equipment very expensive. A vacuum chamber 1 contains an ion source 2 and an extractor electrode system 3, and in the vacuum chamber, a liner 4, which covers said ion source and extractor electrode system, is provided across an insulator 5. Further, in the vacuum chamber, a beam guide 7, which guides the ion beam out of said extractor electrode system, is provided across an insulator 8. Around said ion beam guide, a mass analyzer magnet 6 is arranged, while a disk chamber 13 is provided across an insulator 9 at one end of the ion beam guide. A deceleration means of electrode apertures 10, 11 and 12, which converge and decelerate the ion beam, is arranged within said disk chamber.

    • In a plastic identifying apparatus (1), a reference light (L1) and a detecting light (L2), each having a predetermined wavelength, are irradiated to an object to be identified (4), and the transmitted lights of the reference light (L1) and detecting light (L2) are received. A detecting value expressing the quantity of light received of the detecting light (L2) is divided by a reference value expressing the quantity of light received of the reference light (L1), to obtain a computed value, based on which performed is identification of plastic forming the object to be identified 4. The wavelength of the reference light (L1) is in a wavelength band (hereat, 1550 nm) in which the light absorptances of all the types of plastics are of the lowest level, and the wavelength of the detecting light (L2) is in a wavelength region (hereat, in the range of 1700 to 1760 run) in which the absorption wavelength bands of many plastics except for PET, such as HDPE, are present.
