Instrument tests with the new Leica AT401

Conference ·
OSTI ID:1007542
In order to evaluate the performance of the Leica Absolute Tracker AT401 we devised a series of tests. The first was to compare the Laser Tracker distance measurements to our interferometer on a 30 m long horizontal bench. The second was a check of the horizontal angle measurement accuracy and the 'level to gravity' feature. The third was to check the warm up behaviour and the instrument stability. All these tests were performed in our underground test facility at sector 10 of the SLAC linac. The air-conditioning was turned off for the duration of the measurements. The temperature in the test facility was stable to 0.1 deg C. As a test that is closer to a real world application we performed part of a simplified version of the ISO 10360-10 test in one of the experimental halls at SLAC. The instrument tested was running firmware version 1.0.373.0.
