We must test the following, shortly before beamtime end:

Without ion beam:  
1. Measure XUV countrate versus laser power (especially in range 20 - 40 mW) 
2. Measure laser power versus laser wavelength + laser beam position (SW) using the Wincam 
3. Measure monitor signal for laser on SW (Gentec & screen) 

With ion beam: 
1.  ??
