Fabrication of Aluminium-carbon fiber bridge, stump and pipe connector for Phase-II upgrade

The CMS experiment will change its silicon tracker completely during phase-II upgrade. There is need to develop light and high precision and durable mechanical structure for silicon modules. The prime purpose of this should also be reducing material in the silicon tracker detector. The group at IIT Madras is involved in R&D of production of this structures. The prime purpose of this should also be reducing material in the silicon tracker detector. We have produced high precision Al-CF bridges, stumps and Pipe connector 47 degrees for HgCAL detector.
