Usage of the track reconstruction framework Corryvreckan in proton therapy — •Christopher Krause, Valerie Hohm, Kevin Kröninger, Jens Weingarten, and Florian Mentzel — TU Dortmund, Dortmund, Germany
The Inner Tracker of the ATLAS experiment requires the optimal performance of its pixel sensors. To test their efficiency, a reliable track reconstruction and analysis for testbeam data is necessary to ensure the precise detection of particles. In the last years, track reconstruction was mostly done with the EUTelescope software, a generic and versatile framework.
In 2017, the new track reconstruction software Corryvreckan was published with the intention to reduce external dependencies without reducing the quality and versatility of track reconstruction in complex environments.
Efforts are made in TU Dortmund to use pixel sensors and track reconstruction software for proton computed tomography. The usage of Corryvreckan for low energy high density proton beams is investigated.
This talk presents the performance tests of Corryvreckan with simulated data. The simulated data is generated with Allpix2 and serves to test the usability of Corryvreckan with beam properties used in proton therapy. Results are further improved through the use of machine learning algorithms to separate true and false reconstructed tracks.
