Review of the expected dose for HFT for Dulinski modified for RHIC operation in FY 2014

The average hit rate during a fill at the inner layer at 1.5 cm radius is covered in:

And it is based on Tom Roser luminosity projections for RHIC

average particle flux at the inner radius of 1.5 cm

Year 2014

dose assuming 40% duty factor and 21 week operation per year
