AB  - A new concept of a multipurpose device for the investigation of a low energy in beam interactions with solid state surfaces is realized in an apparatus for surface analysis by means of low energy ion scattering (LEIS), direct recoil spectrometry (DRS), mass spectrometry of recoil ions (MRSI), and secondary-ion mass spectrometry (SIMS). This device provides broad alkali ion beams, homogeneous and much more intense than in standard commercial realizations available, as well as various high quality intense gas ion beams. A long tube with a magnetic quadrupole triplet is introduced. This construction disjoins the high vacuum from the ultrahigh vacuum (UHV) parts of the system and makes possible low cost differential pumping. The use of an UHV broad alkali ion beam in SIMS experiments should importantly decrease crater effect problems without use of rastering and electrical gating systems. In order to demonstrate the possibilities and the advantages of the proposed concept, we present the results of experimental analysis of primary ion beam characteristics, as well as LEIS and DRS experimental results obtained by use of gas ion beams scattered from silver polycrystalline surfaces. This design concept results in a simple and low cost device with operating characteristics comparable to those of high quality devices of similar type. (C) 2000 American Institute of Physics.

AB  - A new fiber-optical dee position measurement system is developed for the VINCY cyclotron. The system includes a sensor head, a coherent optical fiber bundle and a light detector with control electronics. The sensor head is placed in the dee, all the electronic components are placed out of the vacuum chamber of the machine, while the position information is carried by the optical fiber bundle. Two sensor heads on the dee enable the measurement of the position of the dee tip in all three dimensions, as well as the twist of the dee, with a resolution better than 50 mu m. The precise dee position measurement can be useful for beam optimization, study of sparking phenomena, and study of phenomena causing errors in RF cavity geometry (vacuum, heating, etc.) These points tend to be even more important in future high current machines.

AB  - A new broad-beam ion source of alkali (K+) ions for use in ultra high vacuum was designed, built and tested. The basic principles used have advantages over gas-fed broad-beam ion sources, because there is no need for differential pumping, and because an intrinsically pure ion beam obviates the necessity for charge-to-mass analysis. The source is based on the effect of thermionic emission of K+ ions from solid potassium aluminosilicate (K2O . Al2O3 . 2SiO(2)) emitter. An ion beam current of 0.4 mA has been achieved at an extraction voltage of 3.5 kV with 1.5 cm beam diameter. The degassed broad-beam ion source in operation does not appreciably influence the background pressure in the ultra high vacuum system.
