140. Silicon-tungsten ECal - Recent Results and Plans

Marty Breidenbach (SLAC)

20/07/2006, 10:30

After reviewing the Si-W ECal, optimized for SiD, we will give recent results on silicon detector results from the lab and on test of the first fully-designed integrated readout chip (KPiX). We will present our near-term plans.

141. The Multi-Pixel Photon Counter for the GLD Calorimeter Readout

Satoru Uozumi (University of Tsukuba, Japan)

20/07/2006, 10:55

The Multi-Pixel Photon Counter (MPPC) is a novel type photon sensor which has great performances feasible for the GLD calorimeter readout. In this talk we present current status and results of the MPPC performance study from a standpoint of the practical use at the GLD calorimeter. Satoru Uozumi

We are planning beam tests of ECAL(W/Sci) prototype using the Multi-Pixel Photon Counter(MPPC) readout system. This talk is about outline of the plan and also contains a status report of the R&D for optimal scintillator strip structure. Saori Itoh Shinshu university, (GLD-CAL)

142. Development of a Scintillator-Tungsten Electromagnetic Calorimeter with Silicon Photomultipliers

Joseph Proulx (University of Colorado at Boulder)

20/07/2006, 11:45

We are investigating the feasibility of a scintillator-tungsten electromagnetic calorimeter. We use silicon photomultipliers in our calorimeter module to detect light in scintillator tiles guided by wavelength-shifting fibers. We observe sensitivity to single visible photons in the photomultipliers, and can discriminate photons on a time scale of under 10 ns. We are currently studying the...

143. Update on the GEM Digital HCal

Jae Yu (UTA)

21/07/2006, 08:30

To meet the requirements for precision jet energy measurements through the particle flow algorithm, the development of hadronic calorimeter technique with an unprecedented granularity is necessary. For this, UTA group has been working on developing a Digital Hadron Calorimeter using Gas Electron Multiplier (GEM) in the sensitive gap. The group has recently developed 30cmx30cm GEM foils...

154. Construction of a Hadron Calorimeter Prototype Section with Resistive Plate Chambers

Jose' Repond (Argonne National Laboratory)

21/07/2006, 08:50

We report on the progress made toward building a prototype section of a highly segmented hadron calorimeter for the ILC. The section includes 40 layers, each with the an area of 1 m^2, of Resistive Plate Chambers, interleaved with 20 mm steel plates as absorber. The section will undergo a detailed test program at the MTBF test beam at Fermilab, planned for 2008. This effort is...

178. Tile scintillator HCal R&D

Dhiman Chakraborty (NIU)

21/07/2006, 09:10

We report on our plans to design and build a prototype that will be fully scalable to a full dtector, and some preliminary results from first trials along those directions. Speaker: Dhiman Chakraborty, NIU/NICADD

155. Calorimetry Plans for the 4th Concept

John Hauptman (Iowa State)

21/07/2006, 09:30

Abstract: The DREAM beam tests revealed that for electromagnetic showers, the energy resolution was limited by photoelectron statistics and the spatial resolution by the 7.2-cm channel size. Both problems are solved by a front-end calorimeter of 2x2x25 cm^3 PbWO4 crystals with dual readout of scintillation and Cerenkov light with SiPMs to preserve the excellent hadronic energy...
