Ellipsometry principle

Elliptically polarized light determined by:

  • 1. Relative phase shift, ∆ = δp – δs
  • 2. Relative attenuation, tan Ψ = IrpI/IrsI

From : I(Ai)/ I0 a = 1 + α sin(2Ai) + β cos(2Ai) Obtain: ε (ω, α, β, ϕ, P) = ε1(ω) + i ε2(ω)

Coherent “low α“ mode at ANKA

  • Single user mode
  • E = 1.3 GeV
  • initial current intensity ~ 50-70 mA
  • lifetime ~ 15 hours
  • effective bunch length < 1 ps
  • spectral range ~ 5 – 50 cm-1
  • 6 blocks of 2 days per year (this will double with IR 2)

Studies are going on to improve the source understanding First successful experiments on solid (SrTiO3) and on protein (Cytochrome c)
