Novel detector type, named "Stripixel" detector developed at BNL, has been applied in the development of a prototype Si strip detector for the PHENIX Upgrade at RHIC. This novel detector type can generate X-Y two-dimensional position sensitivity with single-sided processing and readout. The prototype Si stripixel detector has an active area of about 3cm×6cm, which is divided into two identical halves. Both X and Y pitches are 80μm, with a stereo angle of 4.6°. There are 384 X strips and 384 Y strips on each half of the detector. The first batch of prototype Si stripixel detectors has been produced at BNL. The initial tests of detector electrical properties have yielded good results. Charge collection tests on test-structure strip detectors have shown both X and Y position sensitivities to laser light. Beam tests on the Si strip detectors have been done at RIKEN in November 2002.
