Description
We report on the development of SVT (Silicon Vertex Tracker) software for the purpose of the SVT and TPC (Time Projection Chamber) relative alignment as well as the internal alignment of the SVT components. The alignment procedure described complements the internal SVT alignment procedure discussed in Star Note 356. It involves track reconstruction in both the Star TPC and SVT for the calibration of the SVT geometry in the presence of a finite magnetic field. This new software has been integrated under the package SAL already running under STAR. Both the implementation and the performance of the alignment algorithm are described. We find that the current software implementation in SAL should enable a very satisfactory internal SVT alignment as well as an excellent SVT to TPC relative alignment
