GlueX - Jefferson Lab

Summary:

 

GlueX is an experiment which takes place in Jefferson Lab's D Hall, located in the United States. The experiment´s objective is to obtain important data to achieve one of Physics most fundamental challenges: the quantitative understanding of the quark and gluon confinement in the Quantum Chromodynamics (QCD). The confinement is a unique characteristic to QCD and to understand it, a comprehension of soft gluon field is required, which is responsible of linking quarks and hadrons.

Characterization of 2800 Multi Pixel Photo Counter (MPPC) ,with the objective of contributing to the GlueX experiment, the High Energy Experimental Physics team committed to the characterization of 2800 Multi Pixel Photon Counter (MPPC) developed by the Japanese company, Hamamatsu, to be incorporated to the Electromagnetic Calorimeter (ECAL) of said experiment. A design and manufacture of the required equipment was made in CCTVal´s Silab laboratory to execute the project, which had three steps applied on the MPPCs: 1) verification of the status 2) collection of parameters 3) Group measurement of 32 MMPCs. The Multi Pixel Photon Counters were sent to Jefferson Lab to be installed and later tested in GlueX, which is expected to be in operation in 2015.

Manufacture of 4000 Lightguides ,the group of High Energy Experimental Physics committed to the manufacture of 4000 Lightguides, to be destined to the Electromagnetic Calorimeter (ECAL) of the GlueX experiment. The order for this manufacture came from Jefferson Lab through an outline of the shape these parts should have. In the Silab laboratory, the most appropriate manufacturing procedure was defined, determining the material (acrylic with UVT optical properties) and the equipment needed, executing the project in three steps: 1) Manufacturing of lightguides with a CNC machine 2) Polishing of the parts with an equipment designed and manufactured in Silab 3) High pressure measurement with a highly specialized machine that for its use the laboratory team was trained. The lightguides were sent to Jefferson Lab for their installation to later be tested in GlueX, which is expected to be in operation in 2015.
