   Data taking all night.
  Had to reduce L21 HV 3850->3825, otherwise tripped every five minutes. An attempt to restore it several hours later was unsuccesful.
   Noted, that oxygen flux in ABS was on eleveted level... and that the nozzle begin to freeze up. It holded less than 2 days! I think, we have to reduce oxygen and see how it holds.
   Started to warm up the nozzle at about 7 am.
   Polarization stays high in crunched data.
