  18   Thu Mar 17 17:37:49 2022 RodolfoAcceleratorHigh voltage dividers for E-CoolerTwo dividers, from PTB-Braunschweig, have
been deliver today. We will use them to monitor
the electron-cooler voltage in situ.

where the laser window is located, looks
suspicious. The sensor E01LF02 shows a value

thick stripper foil and put the ion beam
(238U92+) on the central orbit.

  93   Tue Apr 5 09:39:01 2022 Danyal & YuriAcceleratorStrahl ist wieder im ESR - Schlitz war reingefahrenDer Strahl ist wieder im ESR! 
Angeblich war einen Schlitz, oder sogar 2,
reingefahren worden. 
  
  94   Tue Apr 5 09:45:47 2022 Danyal & YuriAcceleratorbeam is back in the ESR - a slit was moved inAnd now also in English :) 

The ion beam is back in the ESR!

it was unclear if we still sit the 229Th89+
line.
