26/10/2007 The last BMu package (DT+RPC chambers) installation in the
cavern into the iron yoke of CMS (Friday 26 October 2007). This operation
marked the completion of the central muon detector of CMS. More pictures

05/07/2004 First installation process of muon barrel packages (DT +
RPC) into the pockets of the CMS iron yoke at SX5. The chambers were first
transported in groups of four from the ISR area (where they were certified
and coupled together) to the construction hall in Cessy (Point 5 or SX5).
Once there, they passed through a fast high voltage and electronic
certification test, before being slid into the insertion cradle.

Completion of installation of DT and RPC chambers before Cosmic
Challenge (Jun/July 2006) in the central barrel ring (YB0). These
silver-coloured rectangular boxes in the gaps between the steel of the
rings (red in the image) detect muons. Chambers for Sectors 4 and 5
(sector 1 is at the 9 o'clock position and the counting is clockwise) as
well as a couple of chambers in the support "feet" (sectors 9 and 11) were
installed after the magnet test. Chambers for sectors 1 and 7 were
installed after lowering of YB0, in the underground cavern (UXC).

Mar 2006 Resistive Plate Chambers (RPCs) detectors, which were
assembled in Pakistan, installed on the backside of one of the discs of
one of the endcap yokes, known as YE+1. RPC are sensitive to the passage
of muons and provide a "trigger" signal for CMS.

24/01/2007 The first DT+RPC installation round on YB+2 right after
the lowering. A total of 8 chambers were successfully installed in 2 days.
DT+RPC packages corresponding to sectors 1 and 7 of the barrel region
couldn`t be installed on surface, since the lowering gantry from SX5 to
UX5 used their gaps to hold the wheels. Therefore this installation had to
be carried out in the cavern.
