Okay, I'm going to try to do some ascii art that i hope will make things
clearer. Itried once already, but then lost the connection, and the
stupid university computer didn't save my file. AAARRRGGGHHH!
anyway, here goes:
Sol is on the left, TC is on the right. R is the retro-reflector, A is
the Asimov
Stage one: acceleration of Retro-rflector. (these photons are ~)
~~~~~~~~~~~~~~~R
the mass of the retro reflector is about 2 E9 Kg (sound familer?)
the beam is 1 E18 watts the reflector gets to .75 C and coasts.
Stage two:
decellerating energy is sent (ahead of the asimov)(these photons are =)
one LY long tail end of accel energy
================> ~~~~R (.75C)
Stage three:
Asimov is accelerated to near light speed (these photons are ~)
~~~~~~~~~~~~~~~~A <================R ( approx C)
Stage four: Sol-based Accel beam cuts out at halfwaypoint.
Just as Retro reflected beam catches up to Asimov
Note, the decell beam (==) will be red-shifted, but that's okay, beacuse
when Asimov plows into it, it will blue-shift it :)
~A <====================== R
Stage five: Asimov uses the decell beam to slow down to Target star.
