DESCRIPTION:Speakers: Dastan Ibadullaev ()\nThe detailed study of properti
 es of superheavy nuclei (SHN) in the experiments with the complete fusion 
 reactions induced by the 48Ca projectile on actinide target nuclei\, which
  lead to 112≤Z≤118 nuclei\, implies the use of heavy ion (HI) beams wi
 th the intensity significantly higher than the one used earlier in the dis
 covery experiments with the 48Ca beam [1]. Synthesis of SHN with Z>118 imp
 lies the use of the heavier than 48Ca beam particles (50Ti\, 54Cr etc.).\n
 In this lecture\, the durability of the entrance window working at high th
 e intensity of heavy ion beams is considered. The durability of the entran
 ce window is estimated as the result of the action of an intense heavy ion
  beam\, such as sputtering\, radiation damage and temperature [2]. The ass
 essments of these actions that determine the durability of the entrance wi
 ndow are discussed. The temperaturstrong texte of the entrance window is c
 alculated as a function of time in the conditions of its pulsed heating by
  means of a heavy ion beam\, followed by radiative cooling with radiation 
 emitted from its surface. The entrance window temperatures are calculated 
 for heavy ion beams\, such as 48Ca\, 50Ti\, 54Cr and 58Fe\, with their int
 ensities expected for the DC-280 accelerator. With these calculations of t
 he temperature dependences against the time of the beam action the optimal
  parameters of the entrance window operation is chosen. Literature.\n1.	Yu
