  1. AGI Inclinometer Georg Gassner, John McDougal, SLACAugust, 2007 • Principle • Accuracy • Undulator Measurements 1

  2. AGI Inclinometer • Principle Essentially a electronic spirit level: 2

  3. AGI Inclinometer • Transient Response 3

  4. Different Sensors • Y Axis: • Range: ± 10 arc degree • Resolution: 1 microradian • Repeatability: 5 microradian • Linearity: 0.03 degree at ± 3 degree 0.17 degree at ± 6 degree • Scale factor: 34mV/degree ~3.5% • X Axis: • Range: ± 1 arc degree • Resolution: 0.1 microradian • Repeatability: 1 microradian • Linearity: 0.1 arcminute at ± 10 arc minutes 0.5 arcminute at ± 20 arc minutes • Scale factor: 7.2mV/arcminute/V ~2.5% 4

  5. Test on Sine Plate and Breithaupt plate (1) In order to verify the accuracy and linearity of the sensors we tested them on a sine plate and for the smaller range sensors on the Breithaupt stand 5

  6. Test on Sine Plate and Breithaupt plate (2) Y-Axis high 6

  7. Test on Sine Plate and Breithaupt plate (3) X-Axis low 7

  8. Test on Sine Plate and Breithaupt plate (2) Y-Axis high 8

  9. Undulator Measurements Purpose: Repeat the setup of the Undulator, regarding roll on the Dover Bench, the Kugler Bench, the CMM and in the Undulator Hall Measurements: on 3 spots at the flats at each end of one Undulator 9
