GRAAL: Gem Reconstruction And Analysis Library
Abstract
MPGD are the new frontier in gas trackers. Among this kind of devices, theGEM chambers are widely used. The experimental signals acquired with the detector mustobviously be reconstructed and analysed. In this contribution, a new offline software to performreconstruction, alignment and analysis on the data collected with APV-25 and TIGER ASICswill be presented. GRAAL (Gem Reconstruction And Analysis Library) is able to measurethe performance of a MPGD detector with a strip segmented anode (presently). The code isdivided in three parts: reconstruction, where the hits are digitized and clusterized; tracking,where a procedure fits the points from the tracking system and uses that information to align thechamber with rotations and shifts; analysis, where the performance is evaluated (e.g. efficiency,spatial resolution,etc.). The user must set the geometry of the setup and then the programreturns automatically the analysis results, taking care of different conditions of gas mixture,electric field, magnetic field, geometries, strip orientation, dead strip, misalignment and manyothers.
