用于NEWAGE方向敏感暗物质搜索的低α发射μ- PIC的研制
Development of a low-alpha-emitting μ-PIC for NEWAGE direction-sensitive dark-matter search
摘要：
NEWAGE是一个方向敏感的暗物质搜索实验，使用微型图案气体探测器（μ-PIC）作为读数。主要的本底源是μ PIC中放射性污染物的α射线。因此，我们开发了一种低α发射的μ-PIC，并测量了它的性能。我们使用基于微型TPC的表面α射线计数器测量了神冈矿μ-PIC的表面α射线发射率。
英文摘要：
NEWAGE is a direction-sensitive dark-matter-search experiment that uses a micro-patterned gaseous detector, or μ-PIC, as the readout. The main background sources are α-rays from radioactive contaminants in the μ-PIC. We have therefore developed a low-alpha-emitting μ-PICs and measured its performances. We measured the surface α-ray emission rate of the μ-PIC in the Kamioka mine using a surface α-ray counter based on a micro TPC.
