WebbThe RDS-112 cyclotron provides a significantly smaller beam spot, resulting in higher overall 165 Er physical yield, despite the lower irradiation energy and smaller target diameter. However, the RDS-112 cyclotron is limited to maximum irradiation current of 20 µA, a factor of 2 below that routinely used with the PETtrace cyclotron. Webb12 jan. 2024 · That was perhaps my luck because when I had been working in nuclear physics for my thesis, I had access to the little cyclotron we had then in Stockholm, where my father [Manne Siegbahn] was the head of the laboratory. This cyclotron was rather capricious, sometimes it had bad vacuum or something else.
