X射线靶及具备该X射线靶的X射线产生装置
摘要：
本发明的目的在于提供一种X射线靶及具备该X射线靶的X射线产生装置，可以防止照射窗的破裂。X射线靶(4)将支撑照射窗(41)的框架分成靠近照射窗(41)的第1框架(42)及其外侧的第2框架(43)，并分别使用不同的材料。利用热膨胀率为1×10‑6/K的金刚石板(41a)形成照射窗(41)，利用热膨胀率为4.8×10‑6/K的Mo(钼)或热膨胀率为4.3×10‑6/K的W(钨)形成第1框架(42)，利用热膨胀率为16.5×10‑6/K的Cu(铜)形成第2框架(43)。这样，通过以照射窗(41)与第1框架(42)的热膨胀率的差小于照射窗(41)与第2框架(42)的热膨胀率的差的方式而构成，因此可防止因为收缩量的差所引起的照射窗(41)的破裂。
摘要（英）：

An X-ray target and an X-ray generation device including the X-ray target, preventing fracture of irridating windows, are provided. The X-ray target (4) divides the frame supporting the irradiation window (41) into the first frame (42) near the irradiation window (41) and the second frame (43) on the outside thereof, and uses different materials.The irradiation window (41) was formed using a diamond plate (41a) having a thermal expansion coefficient of 1*10-6 / K, and Mo (molybdenum) having a thermal expansion coefficient of 4.8*10-6 / K or a thermal expansion coefficient of 4.3*(Tb) of 10-6 / K to form a first frame (42), and a second frame (43) is formed by Cu (copper) having a thermal expansion coefficient of 16.510-6 / K.In this way, the difference between the difference in thermal expansion coefficient between the irradiation window (41) and the first frame (42) is smaller than the difference in the thermal expansion coefficient between the irradiation window (41) and the second frame (42).It is possible to prevent the rupture of the irradiation window (41) due to the difference in the amount of shrinkage.
