28
Findings From Calibration Studies J Volk Fermilab IWAA 11 Sept 2010 The capacitive sensors calibration is good to 0.5 micro meters as determined by water filling tests. The temperature dependence of the capacitive sensors has a hysteresis and varies from sensor to sensor. This could be an electronic effect and will need more testing. Need to split analog and digital parts test separately. The ultrasonic sensors have a larger temperature dependence than the capacitive sensors. The electronics for the ultrasonic sensors is very stable as measured by separate tests. Change in water level can not be totally accounted for by water expansion. Need to test transponders to fully understand temperature effects.
29
Conclusions J Volk Fermilab IWAA 11 Sept 2010 HLS can provide useful information for accelerator operations. Resolutions of less than 1 micro meter are possible. Stability test of systems needs more work. Temperature dependence of electronics needs to be studied. There is a need to cross calibrate different systems
