Analyses of Test beam data for the ATLAS Upgrade Readout Chip (ABC130). — •Richard Peschke for the ATLAS collaboration — DESY, Hamburg, Germany

As part of the ATLAS phase II upgrade it is planned to replace the current tracker with an all silicon tracker. The outer part of the new tracker will consist of silicon strip detectors. For the readout of the strip detector a new Analog to Binary Converter chip (ABC130) was designed. The chip is processed in the 130 nm technology. In laboratory measurements the preamplifier of the new ABC130 showed a significant lower gain than expected. From the measurements in the laboratory it was not possible to distinguish if the malfunction is in the preamplifier or in the test circuit. Therefore an unbiased test was mandatory. Among other measurements, one was a test beam campaign at the Stanford Linear Accelerator Collider (SLAC). The result of measurement is shown in the presentation.
