• Critical wavelength emitted (even at the flat top energy 28 µm) is far from the detectable range
• Expected light results to be the Edge radiation
• Short distance between the two dipoles lead to interference phenomena

integrated energy per turn over the detectable range in function of the energy
α ɣ12.8
• From E≈400 GeV the emitted light is comparable to the LHC emitted by the LHC undulator at 450 GeV
• Therefore it is reasonable to foresee an SR monitor at flattop energy in the SPS

• Hardware Fully installed for a flattop measurement
• Software missing for a safe image acquisition with no expert tools
• Hardware missing for a continuous measurement along the ramp• (function generator for the gain control).
• If optimized acquisition could reach 30 frames per seconds (expert tools)
