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. ...

... For reliable estimation of the accuracy of asteroid CCD observations we usually consider from ten or more various NUMBERED MINOR PLANETS (NMPs) observed during several nigths per month (more then 50 positions). ... They can be considered as an indicator of accuracy of the CCD positional observations with given MPC code. ... For any NUMBERED minor planet the (O-C) values must be zero if the errors of observations and the errors of its theory are absent. ...
