Description

A novel double-mesh micromegas TPC has been developed in the MATE collaboration. This two-stage amplification structure achieves high gain and low ion backflow at low low-pressure. As a tracking detector, it is successfully applied in the direct measurements of the 12C+12C fusion reaction at stellar energies with beam intensity of 80-90 puA. In this report, I will present the recent 12C+12C experimental result and the extension into (p,a) and (a,d) direct measurements with mA level high beam intensity.
