激光电离μ介子可以产生小动量宽度的μ介子束,即所谓的超慢μ介子束。为了实现高效的超慢μ子产生,需要Lyman-α和低于360 nm的相干光将μ子从基态共振激发到2 p,并将激发的μ子依次电离到未结合态。在J-PARC MLF超慢μ子光束线上,我们使用全固态激光器和高效真空紫外光产生技术成功地产生了超过10 μJ的莱曼α相干光。在本文中,我们将描述强莱曼α光源。
A small-momentum-width muon beam, so-called ultra-slow muon beam, can be generated by laser ionization of muonium. To realize efficient ultra-slow muon generation, the Lyman-alpha and below 360 nm coherent light are required to resonantly excite the muonium from the ground state to 2p and sequentially ionizes excited muonium to the unbound state. At the J-PARC MLF Ultra-Slow Muon beamline, we have successfully generated Lyman-alpha coherent light exceeding 10 μJ using an all-solid-state laser and high-efficiency vacuum ultraviolet light generation technologies. In this paper, we will describe the intense Lyman-alpha light source.
