摘要
为了提高伽玛射线后向散射器件的对比度和成像能力,提出了一些改进措施,以达到降低器件固有噪声的目的。仿真结果表明,所提出的屏蔽系统除了使用68 Ge γ射线源外,还能显著降低器件的本征噪声。
Intrinsic noise reduction of a Gamma-ray Backscattering imaging device
In order to increase the contrast and to improve the imaging capabilities of a Gamma-ray Backscattering device some changes are proposed with the aim of achieving a reduction of the intrinsic noise of the device. Simulated results suggest that the shielding system proposed, in addition to the use of a 68 Ge -γ ray source, produce a considerable reduction of the intrinsic noise of the device.
