    Notes: This paper reports the results of the operation, under active computer control, of a high-voltage (400 kV) injector. The automation system uses a microcomputer placed on the high-voltage deck of the ion source, which takes over some of the process control decisions, and a master IBM-PC at ground potential. Various ion beams (p, H+2, H+3, d, He+, He2+) have been produced, proving the reliability of the system. A maximum value of 460 kV accelerating potential has been reached during the tests. The beam fulfills the requirements for the operation of a room-temperature IH linac. By using a modular expandable computer system the acceleration voltage is continuously adjusted keeping its standard error within 0.1%. A future enlargement of the injector has been taken into account and the upgrading of the control system for an electron cyclotron resonance ion source would be very simple. © 1996 American Institute of Physics.

    Notes: Abstract Quantitative analyses of various silver coins from the first century BC, found on current Romanian territory (Thasian tetradrachmae, Apollonia and Dyrrachium drachmae, Roman republican denarii) were performed using PIXE (3 MeV external proton beam) and XRF (1.1 GBq241Am source). The elemental analysis provided evidence of a great variety of monetary alloys and helped Romanian archaeologists to classify the coins, in terms of their provenance, as originals, copies or imitations minted in different areas of the Balkan-Carpathian region.
