... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...

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. ...
