Infrared camera
Big success for the infrared camera purchased as part of the “Science and Society” work of the group during the European Heritage Days!
About 100 people had their picture taken.

Study of Phase Reconstruction Techniques applied to Smith-Purcell Radiation Measurements
A new paper submitted to ArXiv:
Study of Phase Reconstruction Techniques applied to Smith-Purcell Radiation Measurements
http://arxiv.org/abs/1512.01282
Measurements of coherent radiation at accelerators typically give the absolute value of the beam profile Fourier transform but not its phase. Phase reconstruction techniques such as Hilbert transform or Kramers Kronig reconstruction are used to recover such phase. We report a study of the performances of these methods and how to optimize the reconstructed profiles.
