ML reports that baking of the upstream section (gas jet interaction chamber plus e-target) has commenced - initially to 50 deg C to check thermocouples.
If OK baking
temperature will be ramped slowly (which I think means c. 10 deg C per h) to limits established for specific components by the e-target.
