Brute-force Minimization Approach for Alignment in CBM — •Nora Bluhme for the CBM collaboration — FIAS, Goethe University Frankfurt am Main, Germany
The CBM experiment (Compressed Baryonic Matter), which is planned at the future FAIR facility (Facility for Antiproton and Ion Research), will be used to investigate heavy-ion collisions at high interaction rates. In such high-energy physics experiments, the track-based software alignment of the detectors is a generic and crucial task. By determining the exact detector geometry, the alignment provides the required accuracy to utilise the high intrinsic resolution of the measurements. This is typically achieved by minimising a χ2 cost function for a set of reconstructed tracks with respect to the alignment parameters in question.
To complement the available alignment tools, an alignment approach based on brute-force minimisation is developed. Potential advantages of this method are tighter parameter handling and the use of more constraint types for more accurate alignment results.
In this contribution, recent progress in applying the brute-force minimisation approach for alignment in the CBM setup is presented.
