• Plastic scintillation counter
• Wrapping material
• Aluminum-metallized film

A new type of a trigger-scintillation counter array designed for the MTV experiment at TRIUMFASAC has been developed, which uses aluminum-metallized film tape for wrapping to achieve the required assembling precision of +/- 0.5 mm. The MTV experiment uses a cylindrical drift chamber (CDC) as the main electron-tracking detector. The barrel-type trigger counter is placed inside the CDC to generate a trigger signal using 1 min thick, 300 mm long thin plastic scintillation counters. Detection efficiency and light attenuation compared with conventional wrapping materials are studied.
