	Laser plasma wakefield acceleration (LPWA)* is one of most popular novel methods of acceleration. The LPWA is very perceptively because the accelerating gradient in plasma channel can be a number of orders larger than in metal structures. But the LPWA has two serous disadvantages as very high energy spread and low part of electrons trapped into acceleration. The energy spectrum better than 10% does not observed anyone in simulations or experiments. It should be noted that the electron's beam dynamics in LPWA is different for underdense plasma (quasi linear mode) and in for dense plasma (non-linear and bubble modes). Non-linear mode is studying more intensive at present and methods of the energy spread decrease are under development ,. But the linear LPWA mode also has interest for practical use. The rate of energy gain is very high in the linear mode also and compact laboratory scale facility could be designed to accelerate the electron beam up to a hundreds MeV. Bunching before injection into plasma channel will discuss to decrease the energy spread and to enlarge the electron trapping efficiency. T. Tajima, J.M. Dowson. Phys. Rev.

Laser plasma wakefield acceleration (LPWA)* is one of most popular novel methods of acceleration. The LPWA is very perceptively because the accelerating gradient in plasma channel can be a number of orders larger than in metal structures. But the LPWA has two serous disadvantages as very high energy spread and low part of electrons trapped into acceleration. The energy spectrum better than 10% does not observed anyone in simulations or experiments. It should be noted that the electron's beam dynamics in LPWA is different for underdense plasma (quasi linear mode) and in for dense plasma (non-linear and bubble modes). Non-linear mode is studying more intensive at present and methods of the energy spread decrease are under development **,***. But the linear LPWA mode also has interest for practical use. The rate of energy gain is very high in the linear mode also and compact laboratory scale facility could be designed to accelerate the electron beam up to a hundreds MeV. Bunching before injection into plasma channel will discuss to decrease the energy spread and to enlarge the electron trapping efficiency.
