Welcome to the LCTPC Japan Home Page

The LCTPC Japan group is developing a Micro-Pattern-Gas-Detector (MPGD) readout TPC for the future linear collider in the "LCTPC" collaboration, which has an Asian subset "LCTPC Asia".

Our Activities

Our R&D program covers the design, prototyping, and construction of a large prototype TPC for linear collider experiments as well as basic studies using a small prototype TPC to help better understand fundamental processes in the TPC. Our current focus is on R&D of GEM (Gas Electron Multiplier) modules.
