|
Below in the schottky spectrum, on left is 203Tl80+ contamination, in middel is 200Hg79+ contamination and on right most is 205Tl81+.
These contaminations cannot be seen on CsISiPHOS but can only be seen on schottky.
The goal now is to get rid of these contaminations by putting slits. |

203Tl80+ impurity is removed by moving scrapper inside ESR.
Only 220Hg79+ is left now |

Tue Mar 31 21:07:05 2020, Ragan, General, Separation of 203Tl80+ and 200Hg79+ using scrapper in ESR
|
It can be seen in the video how 203Tl80+ (on extreme left) and then 200Hg79+ (in middle originally) is separted from 205Tl81+ by using scrapper in ESR.
Now, we want 205Pb81+ mixed with 205Tl81+ to be separated as much as possible in FRS. |

|
On 1 April by 5 pm, we could stop the stochastic cooling after the stacking process and also change the orbit of the Tl beam to centre.
Thanks to the efforts by the ESR team ! |

From Yury,
For now, measure the beam life time with 3 different electron current in the e-cooler,i.e. 200mA(default), 10mA, and 20mA. For each current, 4 sets of |

|
We have an EPCIS server (ioc) running on our raspberry (ext-027377). It talks to our MesyTec modules (MSCF shapers, MHV4 high-voltages).
In principal it should be running all the time, but here is the manual how to check/start it:

You need a DAQ-PC and the RIO crate computer.
All of the DAQ proceedures laid out here are operated from inside the DAQ screen session.
Right now for e121 the following DAQ-setup is used: (might change in the future)
