Re: Video camera for use in high magnetic field

Hi John,

Some manufacturers make board level versions of their cameras where the sensor is separated from the rest of the camera with a ribbon cable, for instance AVT:

I don't know if that would give you enough distance though...

Thanks,

Tom

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,
