1. Update on 50um Timepix Assemblies and Sensor Procurement Mathieu Benoit

2. Introduction We received 7 Advacam 50um sensor assemblies last week First results shown so instability of the sensor (bias voltage needed to be operational drifted with time) – After resting the sensor for 48h, changing to a k2410 for biasing, everything seems back to normal – Full depletion at 15V, stable over a weekend taking Fe55 data

3. Depletion Study : C04-W0110 Problem : Baseline move quite a lot as we ramp bias voltage to the sensor, causing zone with very noisy pixel masking the data if not tuned correctly Solution : We performed tuning at each bias point and try to « save » as many pixel as possible
