the beam coming from |

| the pion
source |
||||||||||||
| | Pion half-life is
18ns or 12m at 200MeV |
|||||||||||
| | So
make the decay channel about 30m long |

| | Grahame designed
an initial version |
|||||||||||
| | Used
S/C solenoids to get a large aperture |

high field (3T mostly, 20T around target) |
