  63   Thu Mar 19 09:43:28 2020 LaszloGeneralStatus of the ESR After two days of tuning the beam, yesterday
evening (~8pm), it was found out that within
one ESR pattern using the new control system
  
  64   Thu Mar 19 15:09:29 2020 JanGeneralstarting off with DSSSD here is my short guide how to start with the
measurement as soon as we have a beam available.
  
  65   Thu Mar 19 19:14:40 2020 LaszloGeneralprimary beam measurement Now our aim is to decelerate the primary beam
(naked 124Xe) down to 10MeV/u. At this energy
we can test our detectors and that how the

least (hard to.see with the cursor the corrct
values on the shottky monitor)

  67   Fri Mar 20 01:11:58 2020 LaszloGeneralTarget - beam jntersection We have managed to find the target position
with the beam by looking at the xray spectra.
The trick was that at 10mev we

the target is switched on. It is because
we use only hydrogen target (but why

energy signals from the silicon are negative
--> wrong polarity of the shapers was chosen

The intensity is too.low at ESR to be visible.
