General comment: We have three tracking efforts. How can we leverage the work to date? How do we move forward effectively?
- Short summary of current effort (~5 slides each)
- Issues impacting design/construction
- Charge division in CDC
- sensitivity to B-field
- wire configuration for FDCs
- assignment of HV groups to wires (i.e. failure modes)
- Effective size of forward hole (nominally 1 deg)
- finalizing CDC geometry
- ...we need to complete this list
- Achieving a robust tracking program for single tracks (multiple scattering, energy loss and position resolution only)
- Not necessarily the "final" or best resolution
- High efficiency over all angles (~1-140, define definite boundaries in angle and momentum)
- Efficiency defined based on a reasonable cut on tracking Chi2.
- Studies must include transition between CDC and FDC.
- Goal: create efficiency and momentum resolution plots on log scales (p vs theta) for pions and protons.
- Studies of multi-track events
- Are there any developments here beyond improvements/refinement of 2.? as a function of events with multiple tracks?
- constraining the vertex?
- Refinements/optimizations of the tracking code
- Kalman filters
- reference trajectory methods
- ... work on these to the extent that they impact studies 1-3.
