For an Off-The-Shelf 200 watt tungsten capillary Hydrogen Atomic Beam Source (HABS)
"The intensity of the source can be controlled by the flow rate of hydrogen and the heating power. The heating power determines the temperature of the capillary. With respect to control of these operational parameters we suggest different procedures for high and low intensity runs."
HABS Data Sheet:
As an aside, it is interesting to compare the JLN work with
that of Scott Little's (Earthtech) Mill's ( BLP) replication effort in late 1897-early 1998:
In later runs Scott used only H2 (at higher pressure) and still saw extensive filament erosion.
