183. Tracking Preamble

Bruce Schumm

19/07/2006, 13:30

An introduction to the tracking sessions at this ALCPG meeting will be presented.

39. Using the TRF tracking toolkit

Norman Graf (SLAC)

19/07/2006, 13:40

An overview of the existing tracking software will be given and examples of its use will be demonstrated.

40. Track fitting, resolution limits and detector optimisation

Nick Sinev

19/07/2006, 13:55

I am going to compare different track fitting algorithms and investigate factors limiting resolution of different track parameters in different areas of phase space (low Pt - high Pt, central-forward). Currently I have only 2 track fitting algorithms available in org.lcsim - simple circle fitter and weight matrix based (SLD-like) algorithm. I hope that Kalman filter based algorithm may be...

41. Outer-Detector Tracking Studies for the SiD

Dr Fred Blanc (University of Colorado)

19/07/2006, 14:10

We present tracking finding studies with the SODTracker package for the outer SiD tracker, and track fitting studies using Kalman filter fitters. Based on seed tracks found in the vertex tracker, the SODTracker uses an efficient propagation algorithm to find tracks in the outer detector. For optimal resolution tracks need to be fit with Kalman filter techniques, taking into account...

204. Seed-based Tracking Algorithm for SiD

Richard Partridge (Off-White University)

19/07/2006, 14:25

One of the approaches to track finding in SiD is to identify track seeds in the silicon pixel vertex detector and then associate hits with the seeds in the silicon strip outer tracker. This talk describes tracking code developed in the org.lcsim framework that constructs track seeds from 3D hit measurements and verifies the presence of a track using the other layers of the tracker. ...

138. Tracking Studies at Santa Cruz

Bruce Schumm

19/07/2006, 14:40

I will discuss results, progress, and open questions regarding the use of Tim Nelson's axial tracking algorithm to "clean up" the tracking by finding tracks that begin outside the reach of the vertex detector.

53. TPC Reconstruction Framework using LCIO and Marlin

Christian Hansen (University of Victoria)

19/07/2006, 14:55

The result of a TPC software meeting at DESY in June is being presented. Detailed common software standards were agreed upon in order to facilitate the exchange of code and data. A MarlinTPC package will be written into a central software repository at DESY.

50. Vertex Tools for the ILC

Joel Goldstein (RAL)

19/07/2006, 15:10

A package of vertex tools for use within exisiting ILC software frameworks is under development by the LCFI Collaboration. I will describe the features that this package will provide, and its current status.

211. ILC Vertexing Software Requirements

Norman Graf (SLAC)

19/07/2006, 15:20

I will discuss some of the design requirements for ILC vertexing and present the current status and future plans for the software.

166. SiD Tracker Design: Status and Plans

Tim Nelson (SLAC)

20/07/2006, 08:30

The SiD concept achieves the performance goals for tracking at the ILC with a novel, all-silicon tracker. This design relies upon new techniques in readout electronics and sensor design that must be successfully prototyped as a proof-of-principle. The current design will be described in detail and the status of efforts to prototype and test the critical components will be discussed.

167. Recent Progress in Tracker Alignment R&D at Michigan

Keith Riles (University of Michigan)

20/07/2006, 08:55

Recent progress in tracker alignment R&D at Michigan will be reported. Dual-laser frequency scanning interferometery (FSI) has proven to work well in reducing systematic uncertainties due to temperature fluctuations which limit single-laser FSI measurements under realistic detector conditions. Results of several recent tests carried out to cross-check the precision of the dual-laser...

168. Long Shaping Time Silicon Readout at Santa Cruz

Bruce Schumm (UC Santa Cruz)

20/07/2006, 09:20

We will report on progress in the development of the readout of silicon strips with power-cycled long shaping-time readout at SCIPP.

203. Status Report of Non-Homogenous Magnetic Field Study

Jason Abernathy (University of Victoria)

20/07/2006, 10:30

We give details of the software being developed at UVic for the study of the effets of a non-homogenous magnetic field on TPC tracking.

163. MPGD-TPC Resolution Studies with Charge Dispersion in a Test Beam

Madhu Dixit (Carleton University)

20/07/2006, 10:50

The Micro Pattern Gas Detector (MPGD) readout TPC, proposed for the International Linear Collider (ILC), will have to measure 200 track points with a transverse resolution close to 100 microns. It will be difficult to meet the resolution goal with conventional MPGD readout techniques if 2 mm x 6 mm pads were used as was initially envisioned. Reducing the pad width to improve...

164. Studies with the Cornell/Purdue prototype TPC

Dan Peterson (Cornell University)

20/07/2006, 11:10

The Cornell/Purdue prototype TPC, first commissioned in December 2004, has an active area of 10cm square and a drift length of 64cm. The present readout includes 56 channels of 14 bit, 105 MHz, flash-ADCs. Revised readout pad boards, installed in March 2006, include a combination of 5mm and 2mm pads. Recent studies of various gas-amplification devices will be discussed. These include...

165. Silicon Pixel Readout for a TPC

Jan Timmermans (NIKHEF)

20/07/2006, 11:30

Latest developments in the application of silicon pixel readout for a TPC will be discussed.

146. Transition of TPC R&D to the Next Phase of Work

Ron Settles (MPI Munich)

20/07/2006, 11:50

A Time Projection Chamber is being investigated as central tracker for the detector at the ILC. To provide a comparison and explore the potential improvements using Micro-Pattern Gas Detectors, Gas Electron Multipliers (GEM) and Micromegas (MM), compared with Multi-Wire Proportional Chambers, which have used up to now in TPCs, several small prototype chambers (diameter ca. 30cm) have...
