[Akhil, Harry]

Work Completed :

 Frequency Counter:

• Interfacing with the Raspberry Pi

• Characterization of the FC:          

                                   - Transfer Function 

                                   - Quantization Noise Estimation

Temperature Actuator:

• Measurement of the Transfer Function

EPICS and Channel Readout:

•  Creating a new Channel Access Server(SoftIOC)
•   Piping data from FC into created channels.              

Frequency Offset Locking(FOL) Box Design and Plan:

• Planning and selection of place for installation.
• Preparation of the box and routing cables.

Work Plan for Upcoming Weeks:

• Calibration of the Thermal Actuator TF and PID loop design.
• Channel Testing after installation of the FOL box inside the 40m.
• Optics:
  • Measure beam profiles of AUX lasers and PSL.
  • Design coupling telescope, given space constraints at end tables
  • Couple lasers into fibers
  • Connect fibers from lasers to fiber coupled Beam Combiner and Photodiode.
• Testing of FOL loop after installation of the complete system.
