 Title: Amplifier Beam Profile over time  

This morning we took data of the beam profile at 4 different points to see the evolution of

  • the beam shape
  • divergence

over distance for all amplification percentages

Data plotted for the distance vs radius for all and divergence in rad is extracted and plotted as a variation of amplification power.

Added is the Excel file with all the details and the PowerPoint for referance

This morning, with Ronic, we opened the compressor box to observe if there is any misalignment of the mounts or the CVBG's

a comparison slide between the Beam Profile over time and measurements we have taken, is included.
 
we noticed today that the images need a rotation, and I took the assumption we did not rotate last year and did the rotation of the previous images.
Comparing the last two images, they look slightly similar. but the one from last year is much better than the current one
(remembering it was taken, when we aligned the CVBG's and the chiller was @23, now the temperature is @25 for the chiller)
 
The image we took today is also better than the one from yesterday.
(we take the image when the compressor box is open)
