ruijiu | General | Instruction of NTCAP for shift person | To start a new run with NTCap, we need to
retart NTCAP.
1. Stop labview program.

Ragan | General | 203Tl80+ 200Hg79+ 205Tl81+ | Below in the schottky spectrum, on left is
203Tl80+ contamination, in middel is 200Hg79+
contamination and on right most is 205Tl81+.

Ragan | General | 200Hg79+ 205Tl81+ | 203Tl80+ impurity is removed by moving scrapper
inside ESR.
Only 220Hg79+ is left now |

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 |

Ragan | General | Stochastic cooling and orbit problem | 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. |

ruijiu | General | setup FRS with 2 g/cm2 degrader. | Yuri sets up FRS with 2 g/cm2 degrader (previous
one is 1 g/cm2). The ESR is not changed.
The contamination should be less now. |

Ragan, Alex, Esther | General | No beam in ESR | The beam is coming from SIS but doesn't arrive
in ESR because the quadrupole magnets in
ESR have failed.

Ragan, Alex, Esther | General | Timing problem with SIS & ESR and problems with stacking | There are further problems with beam stacking
in ESR. It works occasionally but keeps failing.
There is also timing problem between SIS |

Alex, Esther | General | Beam in ESR lost | The beam in ESR was lost suddenly at ~22:20
due to a power supply failure of the quadrupoles.
