    Notes: The mVINIS ion source is one of the major machines of the TESLA Accelerator Installation, at the Vinca Institute of Nuclear Sciences. It is an electron cyclotron resonance ion source with multiple applications. It can serve as an injector for an isochronous cyclotron providing heavy ions for several high energy experimental channels (radiation physics, radiation biology, physics of thin crystals, nuclear physics) or as a stand alone machine directly delivering multiply charged ions to the low energy experimental channels (physics of multiply charged ions, surface physics, surface modification of materials). This article describes the completion of mVINIS that included the finalization of its safety and control systems, the fine adjusting and calibration of its gas inlet system, and the installation of the solid substance inlet system. The recent results obtained with ion beams produced from gases and solid substances are presented, showing the wide capabilities of this machine. The ion beams obtained from mVINIS have been used in the channel for modification of materials since May 1998. © 2000 American Institute of Physics.

    The L3A facility at the Vinca Institute: Surface modification of materials, by heavy ion beams from an electron cyclotron resonance ion source : The 8th international conference on ion sources (2000)

    Notes: This article describes the L3A experimental facility for surface modification of materials at the Vinca Institute of Nuclear Sciences, in Belgrade. This facility was completed and put into operation in May 1998. It is connected to the mVINIS ion source, an electron cyclotron resonance ion source capable of producing a wide range of multiply charged ions from gaseous and solid substances. The heavy ion beams obtained from mVINIS are separated by charge to mass ratio (q/m) and transported to the target chamber for sample irradiation and modification. The target chamber is equipped with a multipurpose target holder, an electron-beam evaporation source for thin layer deposition, a residual gas analyzer, and other auxiliary equipment. There is also an additional low energy argon ion source for target preparation/sputtering and for ion beam assisted deposition. In this article we describe the layout and performances of the L3A facility, the experience gained during 1 yr of operation, and the requirements imposed by the current and future experimental programs. Currently, there are 24 experimental programs competing for the ion beam time at the L3A facility. © 2000 American Institute of Physics.

    Measurements of specific heat and electrical resistivity of austenitic stainless steel (St. 1.4970) in the range 300–1500 K by pulse calorimetry (1992)
    Springer
    International journal of thermophysics 13 (1992), S. 57-64

    Notes: Abstract A direct heating pulse calorimetric technique has been applied for the measurements of specific heat, electrical resistivity, and hemispherical total emissivity of austenitic stainless steel (St. 1.4970), a candidate for thermal conductivity standard reference material. The specific heat and electrical resistivity were measured in the range 300 to 1500 K, and the hemispherical total emissivity was measured in the range 1300 to 1500 K. The maximum measurement uncertainties were estimated to be 3% for specific heat, 1% for electrical resistivity, and 5% for emissivity.

    Subsecond thermophysics research at the Boris Kidrich Institute Vincha (1992)

    Notes: Abstract In the early eighties, at the Boris Kidrich Institute Vincha, a method for measuring specific heat and electrical resistivity of electrical conductors in the millisecond resolution range was developed for measurements from room temperature to 1900 K. Over a period of nearly 10 years, the method was applied to different materials, including pure metals, ferrous, and nickel/ chromium alloys, and to the characterization of candidate materials for thermophysical property reference standards. This paper describes the method and reviews the results obtained in specific heat and electrical resistivity studies of ferromagnetic and other materials. The paper also demonstrates capabilities of the method for describing phase transitions or anomalies in pure metals (Fe, Co, Ni) or alloys (Nichrome, austenitic stainless steel).
