abstract = {The local Cosmic Ray (CR) energy spectrum exhibits a
spectral softening at energies around 3 PeV. Sources which
are capable of accelerating hadrons to such energies are
called hadronic PeVatrons. However, hadronic PeVatrons have
not yet been firmly identified within the Galaxy. Several
source classes, including Galactic Supernova Remnants
(SNRs), have been proposed as PeVatron candidates. The
potential to search for hadronic PeVatrons with the
Cherenkov Telescope Array (CTA) is assessed. The focus is on
the usage of very high energy γ-ray spectral signatures for
the identification of PeVatrons. Assuming that SNRs can
accelerate CRs up to knee energies, the number of Galactic
SNRs which can be identified as PeVatrons with CTA is
estimated within a model for the evolution of SNRs.
Additionally, the potential of a follow-up observation
strategy under moonlight conditions for PeVatron searches is
investigated. Statistical methods for the identification of
PeVatrons are introduced, and realistic Monte-Carlo
simulations of the response of the CTA observatory to the
emission spectra from hadronic PeVatrons are performed.
Based on simulations of a simplified model for the evolution
for SNRs, the detection of a γ-ray signal from in average 9
Galactic PeVatron SNRs is expected to result from the scan
of the Galactic plane with CTA after 10 h of exposure. CTA
is also shown to have excellent potential to confirm these
sources as PeVatrons in deep observations with O(100) hours
of exposure per source.},
