Nuclear resonant γ-ray absorption has important practical applications through Mössbauer spectroscopy. At synchrotron-radiation facilities, it is most often used in the time domain, i.e. analysis of the temporal patterns after pulsed excitation. In this context, superradiant speedup and directional re-emission are observed. This text proposes ways to manipulate the superradiant emission in energy/time and momentum/space by introducing controlled dynamic-phase shifts using, for example, static or pulsed magnetic fields. Possible applications are discussed, in particular a solution to the prompt-pulse problem, i.e. the massive overload of detectors by the synchrotron-radiation pulses.View full textDownload full textKeywordssuperradiance, control, nuclear resonance, prompt-pulse problem, dynamic phase, pulsed magnetic fieldRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/09500340.2011.615953

机译：核共振γ射线吸收通过穆斯堡尔光谱法具有重要的实际应用。在同步辐射装置中，它最经常用于时域，即分析脉冲激发后的时间模式。在这种情况下，观察到超辐射加速和定向再发射。本文提出了通过引入受控的动态相移（例如使用静态或脉冲磁场）来控制能量/时间和动量/空间中超辐射发射的方法。讨论了可能的应用，特别是解决了瞬发脉冲问题的解决方案，即同步加速器辐射脉冲使探测器大量过载。查看全文下载全文关键词超辐射度，控制，核共振，瞬发脉冲问题，动态相位，脉冲磁fieldRelated var addthis_config = {ui_cobrand：“泰勒和弗朗西斯在线”，servicescompact：“ citeulike，netvibes，twitter，technorati，delicious，linkedin，facebook，stumbleupon，digg，google，更多”，发布号：“ ra-4dff56cd6bb1830b”};添加到候选列表链接永久链接http://dx.doi.org/10.1080/09500340.2011.615953
