2. ATLAS pixel detector radiation damage monitoring and modeling status report

Ben Nachman (Lawrence Berkeley National Lab. (US))

11/19/19, 3:55 PM

This talk presents updated measurements of fluence-sensitive radiation damage quantities with the ATLAS pixel detector. In particular, the first full Run 2 fluence measurement using the leakage current is presented. The mismodeled |z|-dependence is observed across all of Run 2 and with measurements of additional quantities. In addition to leakage current, the depletion voltage is also...

18. A status update on the CMOS work package within the CERN-RD50 collaboration

Mr Samuel Powell (University of Liverpool), Samuel Powell (University of Liverpool (GB))

11/19/19, 4:15 PM

This contribution will present the status and latest results of the CMOS work package within the CERN-RD50 collaboration. This will consist of describing the RD50 Data AcQuisition System (DAQ) for the test chip RD50-MPW1 and the obtained results, including chip hit maps and pixel address decoding debugging. Measurements of the effects of the clock rate of the on-chip state machine on the...

11. Improving spatial resolution of radiation-tolerant pixel sensors

Sinuo Zhang (University of Bonn (DE))

11/19/19, 4:35 PM

We present a general concept to improve the spatial resolution of silicon pixel detectors via introducing position dependent inter-pixel cross-talk. By segmenting the readout implantations and AC-coupling the resulting sub-pixels, a part of the pixel charge is shared with neighboring pixels. Simulations to study the impact of different coupling capacitor values on spatial resolution are...
