The main purpose of this research is to construct a Tagger Microscope for use in the GlueX project. Issues that are currently being addresses include; how to cleave and polish a two millimeter square acrylic optical fibers, how to then couple scintillators to acrylic waveguides, how to couple the scintillator waveguide pair to a SiPM (silicon photomultiplier). Optically clear two competent epoxies are being experimented with to couple the scintillators to the acrylic waveguides. Preliminary testing with optically clear epoxies show promising results, that is, epoxies are proving to be a reliable way to couple the fibers with minimal transmission loss. Designs for a device to couple the scintillator waveguide pair to the SiPMs, called a chimney, are being developed. The prototype chimney is expected to be completed used in further testing in the near future.

Since the discovery of the atom, physicists have been trying to figure out what exactly is the most basic form of matter. Jefferson National Laboratory, has come up with a way to take a closer look inside the nucleus of the of the atom in the hopes of finding new forms of matter. The way to do this is by shooting a beam of electrons at a target and to produce photons, or light particles, with very high energy . The University of Connecticut Nuclear Physics group is designing a detector to “tag” the amount energy the photons will have. This “tagger” will use massive electromagnets to bend the beam of electrons. The electrons with the higher energy will bend gradually, and the electrons with lower energy will bend sharply. The bent beam of electrons will then hit an acrylic fiber known as a scintillator. A scintillator is a material that when struck by an electron, will produce photons. These scintillators are glued to “waveguides” that guide the photons to photon detectors. When one of the photon detectors reports that it saw a photon, we can determine the energy of the electron based on how far down the line of detectors the electron went.
