  Within CERN RD50 Collaboration, MCz Si was identified as a best material for
the detector used in the high luminosity collider experiments. The n in p Si
detectors were utmost radiation hard detectors, which can be used for the phase
2 upgrade plan of the new Compact Muon Solenoid tracker detector in 2026. The
choice of n or p-MCz Si material depends upon the high electrical charge
collection efficiency performance of these detectors over n or p-FZSi
detectors. The bulk radiation damage model for n, p-MCz Si need to develop for
the designing, development and optimization of the advanced detectors for the
next generation High Energy Physics experiments. In this work, an advanced four
level deep-trap mixed irradiation model (E5, CiOi, E(30K), H(152K)) for n-MCz
Si is proposed by the comparison of experimental data on the full depletion
voltage and leakage current to the Shockley Read Hall recombination statistics
results on the mixed irradiated n-MCz Si PAD detector. Prediction uncertainty
in the radiation damage mixed irradiation model considered in the full
depletion voltage and leakage current, which was due to the uncertainty in
macroscopic results from an experimental measurement on the mixed irradiated
n-MCz Si pad detector. A very good agreement is observed in the experimental
and SRH results on the full depletion voltage and leakage current. This model
is also used to extrapolate the value of the full depletion voltage at
different mixed (proton + neutron) higher irradiation fluences for the thin
n-MCz Si microstrip detector
