The Decay Channel (ctd.)
• Developed a more accurate code
• Used it to validate Grahame’s design…
– 3.1% of the pions/muons were captured
• …and parameter search for the optimum
– Within constraints: <4T field, >0.5m drifts, etc.
– Increased transmission to 9.6%
• Increased in the older code (PARMILA) too
– Fixed a problem in the original design!
