D? Graphics Sampler

• Visual Alignment Package
• Authors T. Trippe, P. Hamel
• Uses 3-D track residual vectors,
• their locations, and errors.
• These contain enough information about tracks and
• detector to do alignment.
• Prototype
• Silicon Microstrip Detector
• Developed new wedge shapes
• Found problems in geometry
• Work in progress

D? Graphics Sampler

• Summary
• Variety of graphics packages
• for various needs of visualizing
• the detector and data.
• Displays have a common basis
• using available libraries.
• Useful for preparing for Run II.
• Modular and robust
• so can be used during the
• course of the experiment.
