sPHENIX MAPS tracker discussion

[Yasser Corrales Morales <ycorrale AT cern.ch>]

Dear all,

    I'd like to submit a poster abstract to Quark Matter on MVTX detector. You can find the draft abstract bellow. Comments and suggestion are always welcome.

Thank you,

Yasser.

The MAPS-based vertex detector for the sPHENIX experiment

A three-layer Monolithic-Active-Pixel-Sensor (MAPS) based vertex detector (MVTX) will serve as the innermost tracking system of the sPHENIX experiment at BNL’s Relativistic Heavy Ion Collider (RHIC). The MVTX detector leverages the Inner Barrel design of the second ALICE ITS and plays an important role in the study of heavy flavor physics within heavy-ion collisions at RHIC. It will cover from 2 cm to 4 cm radially, full azimulthal coverage and a pseudorapidity range of |η| < 1.1. The very fine 27 μm x 29 μm pixels allow us to identify B-decay secondary vertices and B-jets in heavy-ion collisions with high efficiency and high purity. The detector is at an advanced stage of testing with several test beam activities having taken place through 2019. In this presentation, we show the current status of R&D efforts towards custom readout and mechanical systems to integrate the MVTX detector into the sPHENIX system. In addition, results from the analysis of the test beam data, used for evaluation of the tracking reconstruction capabilities for heavy flavor production studies will be presented.
