在FNAL为PXIE设计了Allison型发射度扫描器，其目标是提供快速准确的相空间重建。该设备已从以前的LBNL/SNS设计修改为在脉冲和直流模式下工作，并增加了水冷前狭缝。广泛的校准技术和误差分析允许将不确定性限制在< 5%的水平（已知警告）。该器件采用16位、1 MHz的电子方案，能够分析分辨率为1 μs的脉冲，从而可以分析中和效应。本文介绍了一个详细的细分的R&D，以及运行后的分析技术。
An Allison-type emittance scanner has been designed for PXIE at FNAL with the goal of providing fast and accurate phase space reconstruction. The device has been modified from previous LBNL/SNS designs to operate in both pulsed and DC modes with the addition of water-cooled front slits. Extensive calibration techniques and error analysis allowed confinement of uncertainty to the< 5% level (with known caveats). With a 16-bit, 1 MHz electronics scheme the device is able to analyse a pulse with a resolution of 1 μs, allowing for analysis of neutralisation effects. This paper describes a detailed breakdown of the R&D, as well as post-run analysis techniques.
