LIGO Document T080044-v1
- Part 2: Using a single two-wire pendulum, investigated whether a permanent set caused by an enforced pitch is observed, whether the effect was proportional, and whether an increase in d distance would decrease the permanent set for a given input displacement. Finer resolution repeat of the work in T080033, including with wires brazed into clamps. Effect still visible at smallest observable tilts.
- This is one document of several exploring hysteresis and alignment issues in the quad pendulum. See related documents for the other documents in this study. T080033 is part 1 of this particular study.
