With Hirata-san.

• Using the horizontal fishng rods I moved the IP close to the setpoint.
• The GAS filters were already close to the setpoint.
• I open the vacuum chamber and aligned the collimator such that the beam reached the suspended mirror close to the centre.
• The I aligned the receiving optics such  that the beams reached both QPDs.
• I made sure the beam in the length sensing path went through the lens at the centre.

Tomorrow I will check the position of the micrometers and aim to set the lenth sensing QPD in a suitable place with respect to the lens.

Hirata-san checked the new screw system for locking the suspended breadboard.
