在欧洲同步辐射设施的高压光束线ID27上开发了一种高效多通道准直器（MCC）装置，以大大减少样品环境中的x射线背景。主要的技术难点在于使用经典的单块设计可以实现的最小狭缝尺寸，使用基于一组独立狭缝的原始概念已经解决了这个问题。然后，制造了一个非常小的50 μm狭缝，从而大大提高了信本比。此外，利用掺杂金属玻璃的x射线扩散信号测量了MCC的传递函数，并有效地校正了原始数据。两个具有挑战性的例子说明了这种新装置的潜力：铁硫液体结构和高压高温下的C（60）聚合过程。
A high efficiency multichannel collimator (MCC) device has been developed at the high pressure beamline ID27 of the European Synchrotron Radiation Facility to drastically reduce the x-ray background from the sample environment in the Paris-Edinburgh press. The main technical difficulty, which resides in the minimum slits size achievable using the classical mono-bloc design, has been resolved using an original concept based on a set of independent slits. Then, a very small slit size of 50 μm was manufactured resulting in a great improvement of the signal to background ratio. In addition, the transfer function of the MCC has been measured using the x-ray diffusion signal of a metal doped glass and efficiently applied to correct the raw data. The potential of this new device is illustrated in two challenging examples: iron-sulfur liquid structures and C(60) polymerization process at high pressure and high temperature.
