Abstract：
A new method for the 2–d low energy electron beam profile measurement is developed. based on the ct(computer tomography) algorithm, multi sets of data about the 1–d beam profile projections are attained by rotating the multi–wire target. then a 2–d beam profile is reconstructed from these projections with ct algorithm. the principle of this method is analyzed theoretically in detail and the initial facilities for the experiment with some results are presented.
