Snowmass discussion groups

Organizing discussion groups at Snowmass 2005

The VTX detector within LDC

Presentation by Steve Worm

The tracking system in LDC

Presentation by Ties Behnke

Calorimetry for a PF detector

Presentation by Steve Magill

Vertex Detector issues

Presentation by Marco Battaglia: Vertex detector configuration, overall review of the different options on the market

Physics potential of vertex detector as function of beam pipe radius

Presentation by Sonja Hillert: The role of the beam pipe radius and its optimisation for the VTX detector.

TPC issues

Presentation by Steve Aplin: How large should the TPC be? How close should the ECAL end cap be to the endplate of the TPC? How much material in front of the end cap is acceptable? How much material can be tolerated in front of the barrel calorimeter?

Forward Tracking

Presentation by Klaus Moenig. In the forward direction, the FTD is currently a system of pixels and disks. How important is its material. How stable is forward tracking? What are the important performance goals for tracking in the forward region?

SI-based tracking in LDC

Presentation by Aurore Savoy-Navarro: The SIT was introduced for track merging and for V0 efficiency reasons. These studies should be redone. Is the current SIT and SET layout optimal? Which role does the material play in the overall track reconstruction?

Forward tracking and the TPC

Presentation by Lee Sawyer: How important is the FCH behind the TPC? Do we need stand-alone tracking capability in there, or is a simple device which adds one or two hits sufficient? Which technology is optimal for the FCH?

Particle Flow review

Presentation by Alexei Raspereza: What is the possible particle flow performance? What have we achieved? (this will be a brief summary of results which will be presented in more detail in the PF session on Monday)

Calorimeter optimisation

Presentation by Graham Wilson: What is optimal thicknes of the ECAL/ HCAL? What is the optimal sampling structure? Is the approach used in the LDC detector so far ok, can it be improoved?

The Muon System

Presentation by Marcello Piccolo: What is the basic design of the muon system? What can be improved?

LDC experimental infrastructure

Presentation by Klaus Sinram.

Machine constraints on the magnetic field

Presentation by Karsten Buesser.

LDC answers to the MDI questions

Presentation by Karsten Buesser.

Calorimetry and gaps

Presentation by Mike Ronan: How important are gaps between the calorimeter components? How important are gaps between the calorimeters and other components such as the TPC? What is the penalty for a round TPC inside an octagonal ECAL, if any? How efficient is the TPC for detecting backscattered particles. How important are these? What is the optimal transition barrel – end cap done? Is the current scheme of a long barrel in front of the end cap optimal? Are there alternatives?

The B-field and the tracker

Presentation by Dan Peterson: What quality of the field do we need in the TPC, SIT, and other detectors? How can we measure and monitor the field distortions at the required level of accuracy? Can the large distortions in the large crossing angle be accounted for? Can control samples be used to improve the knowledge of the field map? Does it make sense to eliminate the plug, at the cost of a shorter magnet and thus a less homogeneous field?
