laser wavelength range changed: 320.12 - 319.60 nm |
|
|
Runs of the morning/afternoon/night shift. The wavelength range is now 320.12 - 319.60 nm.

Laser spot seems to drift slowly to an inner position (left on the screen). This might be due to an interplay between a decreasing laser power and the position sensitive detectors of the beam stabilization.
