Mimosa 32-ter Chip Characterisation

The Inner Tracking System (ITS) is a very important part of the ALICE detector. Present ITS is made up of 6 coaxial layers of silicon detectors (2 SPD, 2 SDD and 2 SSD).

description The Inner Tracking System (ITS) is a very important part of the ALICE detector. Present ITS is made up of 6 coaxial layers of silicon detectors (2 SPD, 2 SDD and 2 SSD). This system has a lot of limitations. Its tracking efficiency and resolution is low. Its readout rate is also very slow. Its not possible to study charm and beauty baryons and mesons with this system. So the upcoming ITS Upgrade plan will try to overcome these shortcomings. A very crucial part in this plan is to replace the existing hybrid sensors by new and advanced Monolithic Active Pixel Sensors(MAPS). In MAPS the sensor and the electronics are embedded in the same chip. The MAPS will reduce the material budget, increase the readout rate and enhance the tracking efficiency and momentum resolution. In this report I will present the results for the Characterisation of MIMOSA 32-ter chip, which is a MAPS. My main aim is to calculate the Charge Collection Efficiency of different sectors of the chip and compare between them. And most importantly to see the effect of irradiation on the chip by comparing the results of Irradiated and Non-Irradiated Chips.
