基于螺线管透镜的中微子喇叭
A Neutrino Horn Based on a Solenoid Lens
摘要：
基于螺线管透镜的中微子喇叭与传统的环形喇叭相比，在与多兆瓦质子源一起研究中微子振荡中的CP破坏时，具有几个潜在的优点。1)螺线管喇叭产生的中微子谱在动量P = P0/（2n + 1）处有一系列峰，其形式与在源到探测器一定距离上中微子振荡几率最大的动量序列相同。2)中微子流是中微子和反中微子的大致相等的混合物。3)相对于宽带中微子束，μ介子衰变产生的电子中微子速率被抑制。4)螺线管磁体的线圈远离目标所在的轴线，因此线圈更容易受到辐射损伤的保护。5)螺线管磁铁很容易与液态金属靶兼容，因为需要与非常强的质子源一起使用。6)螺线管磁体是DC装置，因此不像常规环形喇叭那样经受脉冲疲劳。
英文摘要：
A neutrino horn based on a solenoid lens offers several potential advantages over a conventionl toroidal horn when used with a multimegawatt proton source to pursue studies of CP violation in neutrino oscillations. 1) A solenoid horn can produce a neutrino spectrum with a sequence of peaks at momenta P = P_0 / (2 n + 1), which has the same form as the sequence of momenta at which the neutrino oscillation probability is maximal for a fixed distance from source to detector. 2) The neutrino flux is a roughly equal mixture of neutrinos and antineutrinos. 3) Rates of electron neutrinos from muon decay are suppressed relative to those in a broad-band neutrino beam. 4) A solenoid magnet has its coils far from the axis where the target is located, and hence the coils are more readily protected from radiation damage. 5) A solenoid magnet is readily compatible with a liquid metal target, as will be needed for use with very intense proton sources. 6) A solenoid magnet is a DC device, and hence not subject to pulse fatigue as for a conventional toroidal horn.
