Numerical Study of Electrostatic Field Distortion on LPTPC End-Plates based on Bulk Micromegas Modules
The R&D activities for the linear collider TPC (LC-TPC) apac1/60/1/cw are currently working on the adoption of the micro pattern devices for the gaseous amplification stage.Several beam tests have been carried out at DESY with a 5 GeV electron beam in a 1 T superconducting magnet.We worked on a large prototype TPC with an end-plate that was built,
