Purpose of the upgrade
Demonstration of the AdvLIGO interferometer technologies
►Prototyping of AdvLIGO LSC
Lock acquisition
- "Prove AdvLIGO LSC actually works"
Green laser locking
- "Realize lock of the arms independently from the main beam"
"Achieve semi-deterministic lock & smooth handing off"
Noise mechanisms / DC readout
- "Discover and/or confirm by a model RSE specific noise couplings"
►Tuned / Detuned RSE comparison
- "Address advantage and disadv. of the tuned/detuned configuration"
- "Demonstrate smooth transition"
►RGC based digital control system
- "Demonstrate complicated LSC code on the connected multiple systems"
- "Establish rapid prototyping methods with simulated plants on the processors"
To do anything useful to make the AdvLIGO easier / faster
►DC&Dither technologies
- Offset lock and handoffs
- AF WFS technique
- "Develop and characterize various new useful techniques"
►Interferometer Diagnosis
- Cavity characterization using aux. laser injection
- "Provide a method of precise in-situ characterization of the interferometer"
►Development / test bench of advanced technologies
- GigE CCD WFS technique
- Adaptive noise cancellation
- "Demonstrate how it works"
- "Understand and improve its limitations"
