Mon Mar 30 01:43:58 2020, Ragan, General, First measurement with 206Pb81+ beam pattern details
|
The following shows the pattern for first measurement in ESR (gas jet is on for = 60*5 secs = 300 secs as it can be seen on step SC7 in pattern).
One injection cycle runs for ~ 6 mins. |

In the picture below, a very nice storage of 206Pb81+ at 200 mA electron cooler current for no gas jet target can be seen in ESR. The measurement started
at 02:24 and we will now finish it in 5-10 mins. We will now do two more measurements for I_cooler = 10 mA ans 20 mA. |

In the ESR picture below, the decay of beam is very fast initially for few minutes and then the decay is constant. But why does it decay for first few minutes
? |
