CMS and End-cap Muon System UCLA is one of the major US institutes in the CMS collaboration. The UCLA CMS group includes all the UCLA high energy groups : Profs. David Cline, Robert Cousins, Jay Hauser, David Saltzberg and Katsushi Arisaka. Among these, Arisaka and Cline's group have contributed to the End-cap Muon Chambers from the initial construction to commissioning and operation. This efforts have been led by a research scientist, Misha Ignatenko for a decade.
The picture above is the 3D illustration of the CMS detector back in 1994 when it was initially designed. It took the next 10 years and ~2,000 people to construct it piece by piece at all over the world.
The construction of seventy pieces of the End-cap Muon Chambers were carried out at the STRB Building in Westwood village adjacent to the UCLA campus from 1995 until 2004. Then all the chambers were shipped to CERN in 2004 and installed in 2004 - 2006 as shown above. Each end-cap muon system was slowly lifted up and down into the cave, then reached to the CMS experimental hall 100 m under the ground.
Our CMS End-cap Muon Chamber was the cover picture of the European version of Newsweek issued on September 15, 2008. Please note the statement, "And It's European", after 15 years of our hard works at UCLA!
The LHC accelerator and the CMS experiment have been running like a miracle for the last two years. On July 4 of 2012, we announced the discovery of the Higgs Particle with 125 GeV mass. The above picture shows one of the Higgs candidates decaying into four muons, where two muons hit the End-cap Muon Chambers constructed by Arisaka's group.
