Ruijiu | Runs | 2nd measurement with 2 hrs storage time (repeat) |
Because the electron cooler was not switched on during beam accumulation in the previous measurement, we repeat this measurement again.
(In the picture below, it can be seen that the beam cooled. On right most is the Tl beam and rest are the contaminants.)

Shahab | Runs | Nice picture from 205-Tl |
In this high contrast Schottky recording, the main three frequency peaks are resolved w.r.t. time from left to right:
203 Hg 80 +, 200 Hg 79+ and 205 Tl 81+
There are also some spurs visible, whose nature is not 100% sure. One possible explanation can be:
Since this is taken during the storage time (gas target still off), we have no separation between parent and daughter ions, the daughter 205 Pb 81+ basically has the same revolution frequency as parent. It is a possibility that after the decay, daughter ions are slowly cooled back to the nominal frequency. Daughter ions are highly charged and have a high velocity, so single ion sensitivity is expected. They come from all directions, but Schottky measures only the longitudinal plane. Symmetric spurs can hence be an indication of this. |
