Extruded scintillator for the Calorimetry applications
An extrusion line has been installed and successfully operated at FNAL (Fermi National Accelerator
Laboratory) in collaboration with NICADD (Northern Illinois Center for Accelerator and Detector
Development). This new Facility will serve to further develop and improve extruded plastic scintillator.
Recently progress has been made in producing co-extruded plastic scintillator, thus increasing the
potential HEP applications of this Facility. The current R&D work with extruded and co-extruded
plastic scintillator for a potential ALICE upgrade, the ILC calorimetry program and the MINERvA
experiment show the attractiveness of the chosen strategy for future experiments and calorimetry. We
extensively discuss extruded and co-extruded plastic scintillator in calorimetry in synergy with new
Solid State Photomultipliers. The characteristics of extruded and co-extruded plastic scintillator will be
presented here as well as results with non-traditional photo read-ou
Quality Control Studies of Wavelength Shifting Fibers for a Scintillator- based Tail-Catcher Muon-Tracker Linear Collider Prototype Detector
Detailed measurements of the wavelength shifting fiber response to a stable and reliable light source are presented. Details about materials, a double reference method, and measurement technique are included. The fibers studied were several hundred KURARAY, Y-11, multiclad, 1.2mm outer diameter wavelength shifting fibers each cut from a reel to about one meter length. The fibers were polished, mirrored, and the mirrors were UV epoxy protected. Each fiber passed quality control requirements before installation. About 94% of the fibers have a response within 1% of the overall mea

Light Pollution Intensity Monitoring with Novel Multi-pixel Silicon Photon Detectors
Nowadays, numerous fields such as Environmental sciences, High Energy Physics, medical
imaging devices, portable radiation detectors, portable light intensity monitors etc., require a robust,
miniature, reliable and readily available photon detector that is stable in a variety of environments, such
as the presence of strong magnetic fields or abrupt light lever changes. The recently available ~1mm2
active area Multi-pixel Photon Counter (MPPC) sensors, produced by Hamamatsu Photonics, have
been found to be reliable and an attractive choice for such applications.
The following sensor characteristics have been thoroughly tested by a number of different
institutions: gain, dark noise, detection efficiency, reliability. These appear to be stable; in addition, the
characteristic spread between numerous devices was assessed. Sensors with larger area are being
developed for imaging and direct-to-scintillator coupling purpose

LCDG4 and DigiSim - Simulation activities at NICADD/NIU
We present two software packages developed to support detector R&D studies
for the International Linear Collider. LCDG4 is a full-detector simulator that
provides energy deposits from particles traversing the sensitive volumes of the
detector. It has been extensively used within the American ILC community,
providing data for algorithm development and detector optimization studies.
DigiSim models real-life digitization effects, converting the idealized
response into simulated detector readout. It has many useful features to
improve the realism in modeling detector response. The main characteristics of
these two complementary packages are discussed.Comment: 8 pages, 7 figures, submitted to LCWS05 conference proceedings. Uses
