* We discussed the beampipe downstream of the beryllium target. Currently there is a 3.5 cm opening in the pipe going into the Pair Spectrometer magnet. Since the beam spot size on the beryllium is about 4 cm, the PS vacuum chamber would need to be replaced with a 6cm opening beam pipe and be at least 6 cm downstream of this.

Minutes and Action Items

  • We discussed the beampipe downstream of the beryllium target. Currently there is a 3.5 cm opening in the pipe going into the Pair Spectrometer magnet. Since the beam spot size on the beryllium is about 4 cm, the PS vacuum chamber would need to be replaced with a 6cm opening beam pipe and be at least 6 cm downstream of this.
