| contents | Direct detection of weakly interacting massive particles (WIMPs) can provide strong evidence of their existence and the directional method would have an advantage over other methods to detect the clear signal of WIMPs. Time projection chambers with micro-patterned gaseous detectors (MPGDs) are one of the common devices used in directional WIMP searches. A micro pixel chamber ($μ$-PIC), one of the various types of MPGDs, with specially selected low background materials (LBG$μ$-PIC) was developed and its performance was studied. The radon emission of the LBG$μ$-PIC was less than 1/60 of that of the $μ$-PIC currently in use. Although a non-negligible gain non-homogeneity was seen for the LBG$μ$-PIC, it can be used for the directional WIMP search with the correction of the non-homogeneity. |
