Research Abstract

High-energy muons sometimes emit gamma-rays, which cause multi-hits near the original muon tracks. It was examined that a drift-tube detector with simple field-shaping electrodes could find the muon tracks. Research and development of a detector was performed based on the idea.
Machining and assembling drawings were prepared, and appropriate parts were selected. The main aluminum body of the prototype detector was formed by a hollow extrusion processing. The high-voltage test was applied for the prototype detectors. The leakage current was less than 2 nA at 3.5 KV with Ar/CO2 environment. Performance tests with using beam is under consideration.
