我们已经开发了一个（n，p）靶室，包括六个目标层之间的七个气体探测器层夹。这种靶室现在通常用于TRIUMF的新（n，p）设施。利用这种布置，可以使用大的总（n，p）靶厚度（> 1g/cm 2），并且靶对总能量分辨率的贡献是中等的，通常小于500 keV。来自六个目标层的数据的同时积累已被证明对于许多应用是非常有利的，例如：（1）使用一种靶材料的多个厚度，（2）在靶堆中包括已知横截面的靶用于归一化，（3）添加靶以获得同时光谱，用于随后减去污染线，以及（4）同时使用几种靶材料。
We have developed an (n, p) target chamber consisting of six target layers sandwiched between seven gas detector layers. This target chamber is now commonly used with the new (n, p) facility at TRIUMF. With this arrangement, large total (n, p) target thicknesses (> 1 g/cm2) can be used and yet the target contribution to overall energy resolution is moderate, typically less than 500 keV. The simultaneous accumulation of data from six target layers has proven to be highly advantageous with a number of applications, such as; (1) using multiple thicknesses of one target material, (2) including a target of known cross-section in the target stack for normalization, (3) adding a target to obtain simultaneous spectra for later subtraction of contamination lines and (4) the use of several target materials at once.
