Hi,

This probably doesn't meet your requirements, but thought I'd mention it...

On at least one beamline at DLS we have a few Bruel & Kjaer charge accelerometers mounted inside a UHV double crystal monochromator. We use their Nexus amplifier to read the signals and feed them into a 16-bit ADC, and we control the amplifier via RS232. Then we do a FFT on the amplifier waveform data. But we only have a few channels to deal with, and we don't actively monitor the data (just analyse it on a ah-hoc basis when we have time).

However, we've only just started to use them so we don't have much experience with them so far. I'm not sure which actual accelerometer we're using, but the manufacturer has a range of different types. We use them for looking for mechanical vibrations in the 1-100Hz range.

Emma Shepherd developed the streams based Epics support for the amplifier.


Cheers,
Matt
