Analytical and Numerical Flash-Algorithms for Track Fits

Flash-algorithm track-reconstruction routines with speed factors 3000-4000 in excess those of traditional iterative routines are presented. The methods were successfully tested in the alignment of the Test Beam setup for the ATLAS Pixel Detector MCM-D modules yielding a 60 fold increase in alignment resolution over iterative routines, for the same amount of alocated CPU time.
