Run Planning Meeting Notes, November 25 - December 1, 2021

Thursday November 25

1. Last 24h:

1. • Solenoid ramped down, cryotarget removed and replaced with the carbon foils (work finished ~12:00)
   • Beni started to ramp up the solenoid. ~19:00 tune beam was delivered into the hall. After harp scans and finishing with the solenoid ramp up, DAQ was prepared for production.
   • First Carbon run at 150nA started ~11:30

1. Issues:
   • DAQ computer was frozen during the afternoon, so a hot reboot was necessary. That could cause some communications issues with some racks, especially with the Pair Spectrometer.
   • Besides that issue, I suggest limiting the DAQ computer just for CODA. I had the experience that the computer gets freeze or lose the GUI when is used with other apps.
   • Not an experimental issue, but important, the mouse from the conference room has disappear.

1. Plan:

1. • run on carbon at 150nA´
   • Rotate the radiators and use both configurations
   1. • It was suggested to stop the beam ALWAYS before changing the radiator configuration (even with the same radiator)
   • Take at least two amorphous runs

1. Analysis update
