Abstract
For purposes of test beam off-line data analysis a modular software framework has been developed and described in theses proceedings. The TbGaudi package allows to handle the test beam data for a set of runs, as well as the set of different devices under test in one-go, and finally obtain an integrated workflow to present the results. All code is written in C++ programming language. A class based design makes it flexible to add any new features of the device under investigation following a plug-in scheme. Currently, the toolkit handles different types of analysis such as charge collection efficiency, track resolution and eta correction, implemented for non-uniform irradiated sensors. The framework is applied for the LHCb upgrade studies for the VELO and UT groups.
Highlights
In high energy physics experiments, silicon detectors are often subjected to a harsh radiation environment, specially at hadronic colliders
The off-line analysis compares the performance after irradiation with several fluences of protons or neutrons from 2 to 8 × 1015 1 MeV neq/cm2 for devices of different vendors taking into account: (a) different silicon substrates (n-on-p or n-on-n); (b) distances from last pixel to the edge; (c) guard rings designs. In these studies the charge collection efficiencies (CCE), track resolution (TR), Eta correction are of particular interest as function of fluence
These are related mostly to data handling including any feature binned to the Device Under Test (DUT) and test-beam run condition which are treated as parameters-of-interest
Summary
In high energy physics experiments, silicon detectors are often subjected to a harsh radiation environment, specially at hadronic colliders. The off-line analysis compares the performance after irradiation with several fluences of protons or neutrons from 2 to 8 × 1015 1 MeV neq/cm for devices of different vendors taking into account: (a) different silicon substrates (n-on-p or n-on-n); (b) distances from last pixel to the edge; (c) guard rings designs In these studies the charge collection efficiencies (CCE), track resolution (TR), Eta correction are of particular interest as function of fluence. The toolkit handles different types of analysis such as CCE, TR and Eta correction, implemented for non-uniform irradiated sensors This proceeding describes the TbGaudi analysis framework as a proposal for a prototype of a general design framework for test beam campaigns, that could be used to obtain a quick ROOT based application for complex test beam data analyses being performed in different facilities and different irradiation sources or profiles
