Abstract:

This is a talk for the 16th Annual meeting of the Northwest section of the APS.

- - -
In the past years, the advanced LIGO project made a significant amount of
progress. Recently, both of the laser interferometers successfully achieved
full resonance and demonstrated stable operation for more than two hours.
The project is now preparing for observation runs by reducing various noises
and improving the duty cycle. Since the aLIGO interferometer employs a large
number of active control systems and a complicated interferometric
configuration, the process of optimizing the control loops and reducing
noise coupling/sources is not always straightforward. In fact, this is the
point where most of the experimental challenges lie.

In this talk, I will present some of the challenges and how we are
addressing them.
