The TRIUMF Isotope Separator and Accelerator phase 2 (ISAC-II) is on the verge of delivering unprecedented intensities of the most exotic nuclei, those that exist in nature only for tens of milliseconds in the most violent stellar events, to a suite of some of the world's most sophisticated instruments for studying the physics of rare nuclei. The preparation and delivery techniques result in beams containing more than one species, that is, "cocktails" with both the exotic nucleus of interest, and ions with the same mass-to-charge ratio. For ISAC-II experiments to be most effective, a means of identifying the various components of the "cocktail" is needed. We propose a compact and relatively simple device called a Bragg detector. This device identifies the components of a cocktail beam by measuring how the beam loses energy in a gas volume. It will use digital signal waveform readouts to process the energy loss profile. Our device will be based on the design of one that was already built and operated successfully by one of the team members for experiments in Europe.

TriumF同位素分离器和加速器第2阶段（ISAC-II）即将提供最外来核的前所未有的强度，这些核中只有在自然界中存在于世界上最暴力的恒星事件中的数十毫秒，对于世界上最精致的稀有乐器的套件，用于研究了稀有的核心构成物理学的物理学。 制备和递送技术导致含有多种物种的光束，即具有相同质量与电荷比的离子的“鸡尾酒”，即“鸡尾酒”。 为了使ISAC-II实验最有效，需要一种确定“鸡尾酒”的各个组成部分的方法。 我们提出了一个称为Bragg检测器的紧凑型和相对简单的设备。 该设备通过测量光束如何在气体体积中损失能量来识别鸡尾酒会的成分。 它将使用数字信号波形读数来处理能量损失曲线。 我们的设备将基于一名团队成员之一在欧洲实验成功建造和运营的设备。
