Benchmark of proton detection using CALIFA at R3B — •Luke Rose¹, Stefanos Paschalis¹, Ryo Taniuchi¹, Valerii Panin², Leyla Atar^2,3, Christian Suerder³, and Marina Petri¹ for the R3B collaboration — ¹University of York, York, United Kingdom — ²GSI, Darmstadt, Germany — ³TU-Da, Darmstadt, Germany

Quasi-free scattering (p,2p) experiment of the Calcium isotopic chain ³⁸⁻⁵⁰Ca at 450 MeV/u were performed by the R3B collaboration as part of FAIR phase 0. We performed a systematic study on the dependency of the quenching of spectroscopic factors to the isospin asymmetry by employing quasi-free scattering reactions in inverse kinematics, extending our previous investigation [Atar et al.] towards this medium-mass region. CALIFA has been used to measure the momentum of both the recoil and the knocked-out proton. In this contribution, we will discuss the simulations that were performed to study (p,2p) reactions using the CALIFA detector to quantify the detector efficiency for protons. This is a critical step in extracting the measured cross sections for the quasi-free scattering (p,2p) process.
