- "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"
