Heavy Flavor Tracker (HFT) an upgrade detector for STAR at RHIC

This talk presents information about the Heavy Flavor Tracker (HFT), a high
resolution vertex detector being developed for the STAR detector system.
This detector will be used to topologically identify D mesons in heavy ion
collisions at RHIC.  The HFT will use monolithic active pixel sensors (MAPS)
developed at Strasburg by Marc Winter's group with IPHC.  Readout
electronics have been developed that provide cluster identification and zero
suppression at full readout speed.  Mechanical concepts are being explored
that will allow rapid detector replacement with stable spatially mapped
devices.  A prototype telescope using MAPS will be inserted in STAR this
year for testing.
