All,
This isn't an EPICS question but I know there is also vast collective knowledge of non-EPICS instrumentation issues.
At CHESS we are constructing a high magnetic field x-ray beamline. A sample view camera, if placed outside the 5 gauss line is essentially an astronomical telescope, to provide ~ 10 um resolution at 5 meters.
If we had something compatible with magnetic fields, i.e has no magnetic material, it could be placed much closer to the sample.
Gige cameras typical have ethernet magnetics.
One could imagine a USB camera. These typically have DC-DC converters which use ferrite inductors or transformers.
I could imagine building a camera from scratch which gets around these issues ( e.g. liner regulators)
But I am fishing for advice.
Thanks,
