[en] CAMS operates an HVEC FN tandem accelerator for use in both basic research and technology development. The accelerator is operated under a distributed computer control system with sophisticated auto-scaling, beam flat-topping, archiving, and recall capabilities, which makes possible rapid and precise switching between experimental configurations daily. Using the spectrometer, the AMS group can routinely measure the isotopes ³H, ⁹Be, ¹⁰Be, ¹⁴C, ²⁶Al, ³⁶Cl, ⁴¹Ca, and ¹²⁹I at abundances as low as 1 part in 10¹⁶

[en] By this study, a graphite calorimeter has been developed to measure the average ion energy from electrostatic ion accelerator (3 MV Tandem Ion Accelerator of the Takasaki Ion Accelerators for Advanced Radiation Application). A graphite calorimeter was designed for measuring the ion beam energy in wide ion energy ranges (from 3 MeV to 10 MeV). By a couple of this study, the ¹ H(¹⁵ N, α γ) ¹² C resonant nuclear reactions (resonant energy 6.385 MeV and 13.355 MeV) has been applied for measuring the absolute ion beam energy serve as a comparative method. The obtained results were compared in terms of resolution and accuracy. Close agreement was found for both methods, the deviation was observed within ± 3%

[en] The HI-13 tandem accelerator was started to install in Nov. 1983 and put into operation in July 1986. It has been running for more than 15000 hours since then. More than 100 programs of nuclear physical researches and nuclear technical applications were carried out on the machine. The operation, maintenance and improvements of the HI-13 tandem accelerator which have been done last years are briefly described

[en] A High Voltage tandem electrostatic accelerator FN model was installed and started up by the Nuclear Regulatory Authority (ARN) on the campus of Ezeiza Atomic Center. Subsequently, the facility was transferred to the National Atomic Energy Commission for a new start up, re-engineering, maintenance, and operation

[en] The significance and principle of lifetime measurements of excited states in nuclei are briefly described. By using the recoil-distance Doppler-shift method, the Doppler-shift attenuation method, and the fast-timing technique established at the in-beam γ terminal of HI-13 tandem accelerator, nuclear structure studies on topical subjects including chiral symmetries and magnetic rotation have been performed. Our experimental results indicate that ¹³⁰Cs shows better chiral characteristics, however, the two candidate bands of ¹⁰⁶Ag could not be a pair of chiral doublet bands. For magnetic rotation, the deduced B(M1) values deduced from the measured level lifetimes clearly demonstrate that the yrast positive-parity band in ¹⁰⁶Ag and both the yrast positiveand negative-parity bands in ¹⁰⁷Ag are magnetic rotation bands. In addition, our lifetime measurement data also provide valuable experimental evidences for the interpretation and understanding of the shape evolution, the shape coexistence, and the critical-point symmetries of shape phase transition in the different isotope chains.

[en] During 1995, a state-of-the-art intermediate voltage electron microscope (IVEM) has been installed in the HVEM-Tandem Facility with in situ ion irradiation capabilities similar to those of the HVEM. A 300 kV Hitachi H-9000NAR has been interfaced to the two ion accelerators of the Facility, with a spatial resolution for imaging which is nearly an order of magnitude better than that for the 1.2 MV HVEM which dates from the early 1970s. The HVEM remains heavily utilized for electron- and ion irradiation-related materials studies, nevertheless, especially those for which less demanding microscopy is adequate. The capabilities and limitations of this IVEM and HVEM are compared. Both the HVEM and IVEM are part of the DOE funded User Facility and therefore are available to the scientific community for materials studies, free of charge for non-proprietary research
