The development of integrated accelerator components would have far-reaching
effects in fields other than high energy physics. Small, inexpensive low energy
accelerate would find considerable applications in medicine and other research
Site selection will present a unique challenge for the next generation machine.
The question is not if it should be built in outer space. The question is where in
outer space. Tidal forces will be a major Factor in siting. The advantages of
siting a machine in outer space are clear. There is no need for a costly tunnel and
shielding. Furthermore, solar energy in outer space is continually becoming more
economical, and it is reasonable to expect that solar electricity in space will be
considerably cheaper than electricity on earth.* If the weight of the accelerator
is kept down to about 1 gram/cm, then the total weight is approximately 1000 Tonnes.
NASA estimates future payload costs at approximately 2 x 105 $/Tonne, so the total
cost of launch from earth is 200 M$, which is not unreasonable. To put this in
context, the USSR put 300 Tonnes of payload into orbit last year. A dream of high
energy physicists for many years has been a truly international or world accelerator.
The concept has suffered from the problem that such a machine would have to be in
someone's country. Since there are no national boundaries in outer space, this next
generation machine is an ideal candidate for the truly "very large accelerator".
*Work performed under the auspices of the U.S. Department of Energy.
**This is quite a different thing from converting solar electricity
in space to microwaves, beaming to earth, rectifying and producing
cheap electricity on earth.
