Abstract

The next generation experiment in high energy particle physics will be International Linear Collider of electron and positron at the TeV scale. The experiment is aim to search the Higgs particle and to measure its properties. The physics program required the detector with high performance. One of the central detector is a Electromagnetic calorimeter, is going to measure the energy and position of high energy photons. Fine granularity and compactness brings to utilize the Si-W sampling detector. Due to high granularity the electromagnetic calorimeter will comprise of the order of $10^8$ readout cells. The recent developed prototype ASIC chip with 36 channels will be used readout of Si-W ECAL. The performance study will discuss of developed ASIC readout with ECAL prototype, use of pulse generator.
