Positron annihilation lifetime spectroscopy study of vacancy cluster evolution in swift heavy ion irradiated HOPG
Isotropic carbon is the material of choice for the rareisotope production target and beam catchers of the future Super-FRS. During operation both components are exposed to high-intensity ion beams and may suffer from radiation damage. To better understand damage formation processes in graphite, irradiation experiments were performed at the X0 beamline using 11.1 MeV/u Au-ions and different flue...

متن کاملPositron annihilation lifetime spectroscopy in nickel ferrite and iron oxide nanopowders
In this study, a positron annihilation lifetime spectrometer was set up and its resolution was optimized. The spectrometer is a fast-slow arrangement with time resolution of 250 ps. To obtain lifetime components and their intensities from analyzing positron annihilation lifetime spectrum, the Pascual software is used. Positrons are from a source of radioactive 22NaCl with 20 μCi activity enclos...
متن کاملپایداری سامانه اندازه‌گیری طول عمر پوزیترون و بررسی نوع و غلظت عیب ناشی از تابش الکترون‌های 10 مگا الکترون ولتی بر نمونه‌های سیلیکونی نوع n و p
Positron annihilation lifetime spectroscopy method with valuation of non-destructive investigation of material, provides information about electron density, defect concentration, type of defects and atoms around the defects. The stability of the system was tested with a source. The time resolution of the whole system has been derived about 365 ps at FWHM. Then n- and p-type silicon samples we...
