Yuri, Shahab | Runs | FRS valves |
We saw reduction in ESR beam life. It turned out that FRS has opened valves and venting caused us reduction of the quality of vacuum in ESR leading to beam loss. We manged to closed GEE5VV so that now beam is stable somehow.
how could you guys!!!!
arrrrgggggggg!!!!!!! |

store 206Pb81+ beam inside ESR and measure its halflife.
The HV of detector is off.
Start DAQ to record the ESR current in lmd file.
Nik is optimizing the gas jet target. So this file is still test run. |

the problem is
due to mbs.
restart mbs.
see an error.
restart again.
the mbs and go4
are working
