Description
A prototype detector, called mini-ICAL made of 11 layers of iron
plates (measuring $4\,m \times 4\,m \times 0.056\,m$ ) with 45\,mm gaps between each layer
was built and operated Madurai, India$\:$(9$^\circ$\,56'\,N, 78$^\circ$\,00'\,E)
to establish the detector performance and to test INO-ICAL electronics in the presence of a
magnetic field. Resistive plate
chambers ($2\,m\times 2\,m$) with 30\,mm strip width are placed between each iron layer to track cosmic
ray muons. The iron is magnetised to a maximum field of 1.5\,T by applying a current
of 900\,A through 32 copper coils. Though the position resolution of RPC detector is much worse
than the conventional trackers in the high energy physics experiments, muon momentum is reasonably
measured within $\sim$ 1\,GeV/c to 5\,GeV/c. Using the folding technique, reconstructed
momentum spectrum is converted to the cosmic muon spectra for the whole momentum range of
$\mu^+$ and $\mu^-$.
In parallel to measure the momentum spectrum, the differential distribution with respect to
the zenith and azimuthal angles are also obtained. The obtained muon spectrums are
compared with the CORSIKA simulated muon with different hadronic models. This paper will
describe the comparison of data and CORSIKA results with different tuning parameters of those models.
