Dave,
The circulating currents through your spark gap will measure dozens or
hundreds of amps during TC operation. I suspect that they will make
magnetic fields that will totally confuse your Hall effect sensor. On
top of that, neither copper nor tungsten are magnetic, so I would not
expect a Hall effect sensor to be able to "see" them
TC environments are very hostile locations for microcomputers because of
all of the RF noise generated.
You might do better with a remotely located photodiode coupled by an
optical fiber link. You would have to shield the fiber input from the
light of the spark gap, but this might be easier than trying to
magnetically shield your Hall sensor.
