1. for generation of an exposure tube component for electromagnetic radiation, comprising:

  • Electron beam source (10) that can divergent bundle (20);

    Arrangement for deflecting (40), described arrangement for deflecting is configured such that described arrangement for deflecting (40) can make launched electron beam (20) deflection;

    AndAnode (50);

    Wherein said anode (50) comprises the first focal spot region (51) and the second focal spot region (52), wherein said arrangement for deflecting (40) is suitable for making launched electron beam (20) deflection, the Part II (22) of the Part I (21) of the electron beam (20) of being launched with change and the electron beam (20) of being launched, described Part I (21) is by described the first focal spot region (51) irradiation, described Part II (22) is by described the second focal spot region (52) irradiation, and wherein said the first focal spot region (51) is when by described Part I (21) irradiation of electron beam that launched (20), be suitable for producing electro-magnetic beams (31), described electro-magnetic beams (31) is oriented as along predetermined direction (61) and leaves described exposure tube component (1), and wherein said the second focal spot region (52) is when by described Part II (22) irradiation of electron beam that launched (20), the possible electro-magnetic beams (32) that is suitable for described Part II (22) generation of the electron beam (20) of avoiding launched is oriented as along described predetermined direction (61) leaves described exposure tube component (1).
