Subject: Update on the cooling system problem 
After waiting for 1-2 hours. I started the BT again on T5 no tripping BT anymore. While writing hardware with DAS T5 responded well.

After starting the HT, i started a new run :

run #206
start @18h02
stop @18h15

the spectrum seem OK.

In both cooling systems the levels are still good, did we refilled the 0 degree cooling system since the beginning?

The vacuum is @ 9.1e-6 in M2C and 2e-5 in 0 degree chamber.

I then left the cooling ON, but stopped both HT and BT on every telescopes.

I join with this entry screenshots of :

- T5 spectra
- BT&HT current before stopping
- DAS window for X&Y
