    keyword=Prasch: Spin-up

    At about 2 pm, I checked the laser alignment to the cell and centered the laser light on the oven window. The cell is pretty well centered in the oven. I then checked the wavelength of the longitudinal lasers. I made a small adjustment to Laser # 5's temperature (19.5 -> 19.3 degrees C). For Laser #'s 3 and 4, I set the temperature on both to 11.0 degrees, and I also reduced the current some to improve the absorption. The reduction in current also reduced the power to 28 Watts on both lasers. After we reach maximum polarization, we will recheck the wavelength and reduce the temperature on the lasers more.

    Note: The first two measurements on the spin-up should be ignored, since I adjusted the alignment after the second one and checked the laser wavelength.
