- I can't vouch for the exact wording, but the basic comment is from
- Robert Forward. I never saw a good explanation of the details, and
- probably wouldn't have retained them if so -- an accelerator expert
- I'm not -- but my dim recollection is that the existing systems lose
- a good many antiprotons because of wanting a relatively narrow range
- of energies, so the antiprotons can be stored and accelerated easily.
- They're optimized for their end use -- high-energy particle physics --
- not for maximum efficiency in antimatter production.
