Here we're listing ideas for undergrad projects of the future along with a few sentence description. Projects need not be only 40m based; can include West Bridge.

Summary Pages for DetChar
Scattering
Do things with ringdowns, GigE cameras, etc. to understand scatter.
Dual wavelength scatter comparison

Seismic State Classifier Using Deep Learning
Revive Mashas Neural Net thing but using more modern stuff and make it display in the control room so that we know what's going on.
- What states to identify?
- What time scales?
- What about noisy seismometer?
- Classifier for beyond seismic? We could use this for OSEMs and QPDs and PSL stuff to figure out laser death.
Bounce, Roll, Violin mode tracker
Big photo maker for optical tables
Linear Rail + Digital Video -> Frame processing to make a single big flat image of the entire table.
Installation of the GigE cameras
BASLER Cameras
HDR Images from GigE Cameras
LUNGO Site Selection Using Satellite Topography Data
We would like to build a 10-40 km detector in a new site. In order to reduce the effects from gravity gradients and wind, we want the BS and ETM buildings to be inside of a mesa, plateau, or small mountain.
Use the new topo data from Surendra at IIT-Hyderabad to find this using some pattern recognition or something. List here the other criteria for site selection: seismic, airports, roads, etc.
C.Ri.Me. experiment: automatic prediction of mode frequencies
Based on the measurement of the first couple of modes, write some software that predicts (based on fitted COMSOL models and/or extrapolation) where the next modes should be. This can be useful both during the measurement time (to optimize the excitation of low modes) or during the analysis, to improve the identification of the modes
C.Ri.Me. experiment: effect of annealing
Measure a substrate many time with different annealing schedules, to determine how the Q changes
C.Ri.Me. experiment: fit measured frequencies to disk parameters
Fit the measured eigenmodes to a COMSOL model, changing diameter, thickness, flat size, etc.
Fourier analysis of high speed images with GigE camera
Run at GigE camera at high speed (>1024Hz) and analyze the high speed images (of any object) in the frequency domain looking for regions of excess noise and correlations with interferometer noise.
