Running Strategy

2

High Lumi (ZDC > 55 kHz):PXL + IST + SSD taken out (we pump di-muon, photon triggers)

Mid Lumi (ZDC 55-40 kHz) and Low (ZDC 40 kHz) : PXL + IST in (priority gradually given to HFT program)

STAR want steady long runs

Luminosity and Events

luminosity hunger

running time hunger

Data Taking Time

• STAR is running efficiently• We need long steady runs for the

minimum bias data set with PXL and IST (silicon vertex detectors)
