Query: RE3/1 and RE4/1 RPC chambers integration in the inner region of the
  forward muon spectrometer in the CMS experiment   The high pseudorapidity ($\eta$) region of the Compact Muon Solenoid (CMS)
muon system is covered by Cathode Strip Chambers only and lacks redundant
coverage despite the fact that it is a challenging region for muons in terms of
backgrounds and momentum resolution. During the annual Year-End Technical Stops
2022 & 2023, two new layers of improved Resistive Plate Chambers (iRPC) will be
added, RE3/1 & RE4/1, which will completely cover the region of $1.8 < |\eta| <
2.4$ in the endcap. Thus, the additional new chambers will lead to increase
efficiency for both trigger and offline reconstruction in the difficult region
where the background is the highest and the magnetic field is the lowest within
the muon system. The extended RPC system will improve the performance and the
robustness of the muon trigger. The final design of iRPC chambers and the
concept to integrate and install them in the CMS muon system have been
finalized. In this report, the main results demonstrating the implementation
and installation of the new iRPC detectors in the CMS muon system at high
$|\eta|$ region will be presented.
