SLIDE 1 Coherent beambeam e#ects study. ... He has shown that a finite length (in other words equal to # # ) of colliding bunches can lead to the coupling of synchrobetatron modes in the beambeam system, and thus a headtail type instability of colliding bunches may arise. ... These modes have been observed in di#erent machines. ... SLIDE 5 Figure shows the dependence of the measured and calculated synchrobetatron mode tunes on the beam current for equal electron and positron bunch intensities. ...
Sp ecific features of differential motions in the DIMM V. Kornilov, B.

Polycyclic aromatic hydrocarbons in HII regions: correlation with metallicity . ... We have perfomed the aperture photometry of HII regions using infrared images from telescopes Spitzer and Herschel at passbands 3.6, 4.5, 5.8, 8.0, 24, 70 and 160 m. Emission of PAHs are observed at passbands 3.6 - 8.0 m, 24 m is emission likely of hot small particles and finally large particles are responsible for emission at 70 and 160 m. We determine abundances of PAHs using model of Draine Li (2007) . ...
