R&D Tags
The R&D conducted for the inner tracking upgrade required that a few specialized geometry tags be created. For a complete set of geometry tags, please visit the STAR Geometry in simulation & reconstruction page. The below serves as additional documentation and details.
Taxonomy:
-
SSD: Silicon strip detector
-
IST: Inner Silicon Tracker
-
HFT: Heavy Flavor Tracker
-
IGT: Inner GEM Tracker
-
HPD: Hybrid Pixel Detector
The TPC is present in all configuration listed below and the SVT is in none.
