Si strip detector


Single-sided SSD for high energy particle position detection


The Si strip detector (SSD) is a Si photodiode with PN junctions (particle detection structures) that are several micrometers to several tens of micrometers in width arranged in a strip formation. Developed specifically for the J-PARC muon g-2/EDM experiment*, this SSD can detect precise incident positions of high-energy particles with remarkable accuracy. It has an active area of about 97 × 97 mm and can detect positions over a wide area.
