... In electron-positron colliders, effect of the lattice modification by opposing bunch focusing on the equilibrium radiation emittance is important at high values of the space charge parameter, so one should correctly evaluate this dynamic radiation emittance of the weak beam, which may differ a lot from the nominal emittance, already in the linear beam-beam force model. ... The linearized beam-beam force is equivalent to focusing insertion in linear lattice of the collider. ...

The diffraction image FWHM at 2.2 microns on the Gemini 8 m telescope is about 0.07". Consequently, a spectrograph with a 0.10" slit is essentially diffraction limited in the K band. ... Slit diffraction causes divergence in the spectral direction of rays through the slit in excess of the geometrical focal ratio; it can be thought of as focal ratio degradation speeding the beam in the spectral direction. ... A perfect image would have no phase coherence across the slit. ...
