Description
The Silicon Tracking System (STS) is the core detector system of the Compressed Baryonic Matter (CBM) experiment at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. CBM will study matter at highest baryonic densities in collisions of nuclear beams with a stationary target. The long latency for identification and the changing signature of the events drive us to use self-triggered streaming readout. CBM data collection will be based on time-stamped detector data into a compute farm. Event reconstruction and physics analysis are performed online at collision rates up to 10 MHz.
In the presented work we will discuss step by step how the detector components are rigorously selected and prepared for assembling. It all starts with careful testing of the readout ASICs at the wafer level or in a manual process. The various parameters are recorded to select the chip. The next step is to test the tap-bonding to the micro cables and later the 16 chip-cables that are bonded to the silicon strip sensor. All test results are stored and available for later use in a specially designed database using custom software that is applied to each step in the assembly process. More than ten percent of the modules will be produced by the time of the presentation so that an overview on the production can be presented.
