TJ, Camilla

After swapping to the old ETMX HWS 530nm diode source and seeing that the HWS signal was not good in 73717, TJ and I this morning confirmed that the mode matching does not match the design. We think we need to adjust the position if the initial collimating lenses, but didn't finish doing this. As we misaligned the beam by movng the fiber assembly D1800125, we left the HWS powered off.
