  2. Comment Electron bunches created in colliding Pulse Injection at LOA have been analysed in energy using a high resolution imaging magnetic spectrometer. In CPI, bunches energy spread was routinely and reproducibly measured to be of the order of 1%. This demonstrates at the same time that the design energy resolution of better 1% over a broad range ha been achieved. Bunch mean energies ranges from 150 to 200 MeV. Bunch charges of the order of 10 pC were observed.
