Conclusion

The experiments done this summer were tests of the electronic equipment that could be used if an accelerometer were to be built to detect ground vibrations for the NLC.   The final calculation showed that with the electronic noise and with the test capacitor in place, the smallest measureable motion due to noise was .413 nanometers in a 5 Hz to 1 KHz bandwidth.   However, this measurement was only taken once, and there could have been experimental errors made.  Assuming the research done this summer was reasonably accurate, the idea of building accelerometers sensitive to nanometer motion seems feasible.
