Important - analysis 
-> we are trying to get PID with a new setting to see if 98Zr decays with 30s half-life
--> we are taking 1 min cycles 
---> strongest line does not corespondents to 96Sr38+ as it decays very fast (few seconds) and we observe long-lived one - still we have to confirm this 

----> analysis is still ongoing 

We lost the beam at 19:35

 

From 17:49 we have super short trigger. - see attached setting! 

Only 96Sr would yield very few line with only ions from time to time.
So we went a bit lower in Brho 7.69 Tm -> 7.65 Tm.
The setting is calculated as a 98Mo39+.
E-SIS = 455.3 MeV/ for 100Mo,
after target 98Mo now with 39+ gives 7.6500 Tm.
In ESR also 39+.
In LISE we get the same average gamma as before for 98Zr (gamma = 1.40082).

The 98Zr was also entered as a 98Mo40+-

NEW SETTING 

All runs from 17:00 are with new setting, due to changing the directory - transfer from old to new one around 200 runs.

Only 96Sr would yield very few line with only ions from tiem to time.

Beam is back at 16:38.

We are changing the setting.

We lost beam at 16:29. 
Cooler has to be investigated. 

HHT have more problems and need to enter the cave, beam is stopped for some time
Beam stop: 05:46
Beam back 6:31

HHT called and said they have problems and need to enter the cave, so they stop the beam for some time
Beam Stop 00:10
Beam back 01:01

Beam dropped between 23:00 and 23:05

since 21:48 particle intensities increased to again to 1.5E9

Intensity in particles dropped from 21:33

since 21:20 the intensity is back to 1.5E9

The intensity dropped at 21:10 from ~ 1.6E9 down to ~ 8E8

19:10 runs from now on run with an optimized setting:

we did a lot of optimization for the hunt of Zr isomer:

1- increased the time as much as possible, but stay within the 1:1 cycle with FRS
2- increased the sampling rate from 6.25 MSPS to 50 MSPS (!) going down to very short recording times --> 300ms only

We are now taking data with this settings for about half an hour.

new timing cycle of 6.7s

Beam is back at 18:32 
now in the particle plot the peaks seem to be more isolated than before (see attachment 1)
since 18:36 it looks like before (see attachment 2)

beam issues between 18:23-18:26
and beam completely lost from 18:27 till 18:32
in the SIS an issue with a dipole occured

beam is back
16:45

HHT sees radiation from us. We stop for 10 min for them to see the speed with which the radiation level decreases.
