Web14 okt. 2016 · In this work, helium ion irradiation of Hastelloy N alloy with subsequent annealing was performed to investigate the evolution law of helium bubbles using ERDA and TEM. The schematic of the coarsening mechanisms (rate) with the evolution of bubble pressure was given. WebThe excited N2+ (2P) ions decay rapidly (1.4ns) to the ground state within the minimum flight time to the second target (10µs), and so produce a beam of ground state N2+ ions. This is the first stage of double translational energy spectroscopy. The ion beam, now consisting of only ground state N2+ ions, is accelerated by lens system L4 into
