Nozzle clogged more when trying warming again.
Warming up, venting top and bottom to clean nozzle.

We have recovered the beam at 01:49, after such a long time we had no target so we increased from 80K to 120K at 01:52. 02:01 update 120K-->95K as we have observed around that temperature always fluctuations and is safer.

So far looks like with a temperature of 95K the target is maintained with a reasonable density throughout long periods of time.

We have decreased the temperatur> 95K --> 90K. At 95K the target was stable, but let's try to increase the density a bit.
