MICE:国际μ子电离冷却实验:相空间冷却测量

MICE: The International Muon Ionization Cooling Experiment: Phase Space Cooling Measurement

Terrence Lee Hart

摘要:

MICE是一个使用一段电离冷却通道和μ子束的实验。μ子将由π介子的衰变产生,π介子来自卢瑟福阿普尔顿实验室(RAL)的ISIS质子束。该通道包括提供横向和纵向动量损失的液氢吸收器和用于纵向再加速的高梯度射频(RF)腔,所有这些都封装在螺线管磁通道中。对于μ子动量在140和240 MeV/c之间的情况,MICE将使束流横向发射度降低约10%。飞行时间(TOF)计数器,阈值切伦科夫计数器和量热计将识别背景电子和π介子。冷却段前后的分光计将测量光束透射率以及输入和输出发射度,绝对精度为0.1%。

英文摘要:

MICE is an experiment with a section of an ionization cooling channel and a muon beam. The muons will be produced by the decay of pions from a target dipping into the ISIS proton beam at Rutherford Appleton Laboratory (RAL). The channel includes liquid-hydrogen absorbers providing transverse and longitudinal momentum loss and high-gradient radiofrequency (RF) cavities for longitudinal reacceleration, all packed into a solenoidal magnetic channel. MICE will reduce the beam transverse emittance by about 10% for muon momenta between 140 and 240 MeV/c. Time-of-flight (TOF) counters, a threshold Cherenkov counter, and a calorimeter will identify background electrons and pions. Spectrometers before and after the cooling section will measure the beam transmission and input and output emittances with an absolute precision of 0.1%.
