Speaker
Description
Since 2011, Korea-CMS (KCMS) has received GEM Foil production technology transfer from CERN RD-51 and has collaborated with Mecaro Co., Ltd. on Research and Development. A large GEM foil, ranging in size from 10 cm² to over 1 meter in length, was produced and supplied to the laboratory. In recognition of these achievements, a Memorandum of Understanding was signed with CERN CMS in 2019 to provide the GEM foil required for the construction of the GEM detector system for the Phase-2 upgrade.
Korea-CMS prepared facilities for mass production in 2020 and, from 2021, began producing GEM Foil. Initially, low production yield and electrical instability were issues, prompting Korea-CMS to implement a Quality Management (QM) system to address them. The problematic foil was selected through Quality Control (QC), and the cause of the problem was analysed using Electron Dispersive Spectroscopy (EDS) and an optical lens. Based on the analysis findings, the Quality Assurance (QA) team improved the production process to enhance product quality. Consequently, the product's performance improved, and the initial low production efficiency of less than 20% increased to more than 80%. Thanks to its successful Quality Management activities, Korea-CMS successfully mass-produced high-quality GEM foil from 2021 to 2026.
