plasma acceleration 125
EXERCISES
6.1 Chapter materials review.
What laser intensity (in W/cm 2 ) would correspond to a normalized vector potential of a 0 = 10, and what are the maximum values of the electric and magnetic fields in the laser
wave, for a ruby laser or for a CO 2 laser?
6.2 Chapter materials review.
Assume that we get 1 GeV electron bunch from a laser
plasma accelerator, and would like to create an undulator
from plasma using the focusing force of the plasma’s ions.
Suggest the plasma parameters and the amplitude of the
beam oscillation that would correspond to the radiation at
the boundary of the undulator regime, i.e., with the undulator parameter equaling K = 1.
6.3 Mini-project.
Assume that the LHC proton beam of E = 7 TeV is going to
be used as a driver for the plasma acceleration of electrons.
Select the parameters for the plasma and estimate to what
bunch length you would need to compress the LHC beam so
that it could be used for plasma acceleration. Define, roughly,
the parameters of the corresponding bunch compressor.
6.4 Analyze inventions or discoveries using TRIZ and AS-TRIZ.
Analyze and describe scientific or technical inventions described in this chapter in terms of the TRIZ and AS-TRIZ approaches, identifying a contradiction and an inventive principle that were used (could have been used) for these inventions.
6.5 Developing AS-TRIZ parameters and inventive principles.
Based on what you already know about accelerator science,
discuss and suggest the possible additional parameters for
the AS-TRIZ contradiction matrix, as well as the possible additional AS-TRIZ inventive principles.
