Quench Behaviour Team meeting
POSSIBLE SCENARIOS FOR TRAINING
E. Todesco
CERN, Geneva Switzerland
Based on production data
(thanks to project engineers and SM18 staff)
Based on the HC data of 2015 and 2008
(thanks to MP3 teams)

2. DATA REMINDER: SECTORS
We are discussing the possibility of
Powering towards 7 TeV some sectors during EYETS
This is essential to have a sample of data that allow to avoid extrapolations of 6.5 TeV behaviour
Having a warm up cool down to have more information about memory
This would add the experience of another sector
For the moment we have 5-6 powered to 6.5 TeV twice
2008 quenches: 23±8
2015 quenches: 16±7
and we have 4-5 powered to 6.0 TeV twice
2008 quenches: 3±6
2015 quenches: 10±6
On this issue it is difficult to have conclusive data, but another sector would be welcome if this does not increase significantly the risk

3. DATA REMINDER: SECTORS
I think we need two sectors towards 7 TeV
As stated in few occasions (LMC , Chamonix)
12 for 1000 and 2000 series behaviour
45 for the second quench of 3000 series

4. DATA REMINDER: SECTORS
If we could warm up and cool down a sector
I would exclude 45 to minimize the number of quenches
12 would give little info on 3000 series
78 early part of production – not significant
23 would be perhaps the most significant
Equal share between 3 series
17 quenches for 6.5 TeV
this is the overhaed
Others (81,67,56,34) would also be ok
56 would give a third point – or better to have another
