# The required beam profile at 2H02A harp is: X-width <~0.25 mm, Y-width <~ 0.10 mm, and the tilt angle <15 degrees. The spot on the Chromax viewer should be close to x=-2mm, y=-5mm. <b> Do not waste too much time on the initial beam tune, as long as rates on the halo counters are low - Downstream L/R/T/B and HPS-L/R <~few Hz/nA, and HP-SC < few x 10 Hz, the following program still can be done:</b> | # The required beam profile at 2H02A harp is: X-width <~0.25 mm, Y-width <~ 0.10 mm, and the tilt angle <15 degrees.
