Dear all,

The test beamtime is now over. 
We had 6 days of Li-like carbon in the ESR (122 MeV/u). 
Effectively, we could measure almost 5 days continuously.  

There were only a few interruptions, one of which was a longer power failure. 
The vacuum in the ESR was not optimal, which strongly reduced the lifetime of the stored ion beam (~30 s) 
and the electron cooler showed weird instabilities, which need to be clarified still. 

Still, we were able to cover all aspects of the program. 
Essentially everything we tried worked. 

Therefore, I conclude that it was a great success. 

Many thanks to all who have contributed to it! 
Special thanks to Sebastian and Benedikt - who worked really hard during the last months - for prepapring the laser system and the data acquisition system. 
Also special thanks to Volker and Ken for preparing the XUV detector system. 

We will start sorting/ordering & filtering the data soon and will invite for a meeting where we present the raw data so that we can discuss it. 
Then we will also discuss the next big step: data analysis. 
Of course it is our next objective (with high priority) to publish the analyzed data in foreseeable time. 

I hope to see you soon. 
Until then, take care and stay healthy,

Danyal
