%0 Journal Article %T Momentum computed tomography of charged particles %A Deyang Yu %J Physics %D 2013 %I arXiv %X The principle of the momentum computed tomography of charged particles is presented. It may be useful for momentum spectroscopy of various beam-matter interactions, especially when very intense beams are involved. It is able to collect the shower of charged particles with the 4Pi solid angle, and suitable for measuring the overall perspective of the arbitrary momentum distribution of the outgoing charged particles induced by arbitrary beams, especially when the other techniques are invalid. The extended collisional region, the strong field approximation and the case without magnetic field are discussed. %U http://arxiv.org/abs/1302.4569v1
