4 August 14, 2007 Internal Presentation Georg Gassner 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% 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%

5 August 14, 2007 Internal Presentation Georg Gassner 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

6 August 14, 2007 Internal Presentation Georg Gassner 6 Test on Sine Plate and Breithaupt plate (2) Y-Axis high

7 August 14, 2007 Internal Presentation Georg Gassner 7 Test on Sine Plate and Breithaupt plate (3) X-Axis low

8 August 14, 2007 Internal Presentation Georg Gassner 8 Test on Sine Plate and Breithaupt plate (2) Y-Axis high

9 August 14, 2007 Internal Presentation Georg Gassner 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 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
