Abstract:	A multistrip silicon detector was fabricated by using planar techniques. It consisted of five parallel pn-junction strips on a wafer of 200 μm thick. The dimension of each strip was 2 mm × 20 mm and the strip pitch was 2.6 mm. The detector was tested by using heavy ions produced in the reaction of ¹⁸¹Ta + ¹⁴N at 210 MeV. We found that it enables clear particle identification for heavy ions and that it shows good property for a position sensitive detector. We studied phenomena of multiple output events induced by a single particle entering the detector; events giving double outputs occurred only in a arrow gap between adjacent strips. Events with more than triple outputs did not exist and insensitive areas were not observed.
