Place of employment does cross linking processing via irradiation.
5 years ago, I designed a counter acting magnetic field generator
along the back wall of one our units. Reason for being is, behind this
wall is the outside which has a road way where fork tucks and other
vechicals drive, just after that, a rail way. When trucks or trains
go by or stop in that area, it creates enough disturbance to cause the
irradiation beam to miss align and causes doscemity changes and heating
of the scan horn. ( not alot but enough to alter spec's)
To fix this, we designed a small wall on the out side of the vault
with an array of coils connected to multi channel DC amps. These arrays
have Hall sensors in them to monitor the change and maintain a fixed
gauss.
Now, the problem. Apparently some communication equipment on the train
gets desensitized when they stop at that location, they need to move
up/down the tracks to correct the issue which some times isn't fun for
them.
My question is, what kind of equipment would a train have that would
get effected from a DC magnetic field ?
