N2 - A high frequency mechanical modulator of photon beam intensity (vibrating reed) affords minimal obscuration of the beam, and precise measurements of beam intensity and position fluctuations. Corrections for the intensity fluctuations of the sample signal at 120 Hz by a wide band multiplier is demonstrated and possibilities for servo correction of sample position errors are indicated.
