3) HPS PC & HARP near HPS
a) Do we need the wire at the bottom of the PC?
·         We have to scan to find the edges of the tungsten slit anyway seeing the rise in signal from the beam tails as we move up and down.
·         We will know the center of the slits well enough from survey to allow positioning of 3mm slit so the beam passes through the slit.
·         We will need physical STOP/switch on stepping motor for reference.
·         Do we use ECal signals during scan to find center of slit?
b) Do we need the thin gold foil on the PC if there is one on the HARP? If we have the thin gold foil on the PC do we need a 3-mm slit before the gold foil to protect stuff downstream?
c) Edit operation manual for HARP to include gold foil?
HPS PC already designed with gold target and wire (see attachments).
