作为对合作的一种投入，来自Andrzej Sojetan核研究所的小组承担了一项任务，即调查用于伽马射线暴光子偏振测量的紧凑型探测器（称为POLAR）设计的有效性。作者着重研究了（200×6×6）mm ~ 3BC 400塑料棒以及其他BC 408塑料样品的闪烁和光输运特性，试图确定组装好的仪器是否能达到该项目规定的性能标准。调查显示，在闪烁体和光电探测器中的前体相互作用之间的信号的幅度和距离之间的强烈依赖性。根据这一发现，已尝试确定表面抛光质量对整体闪烁体性能的影响。作者认为，闪烁体片的适当加工、其包装的适当选择以及适当的软件分析可以克服所揭示的缺点。
As a form of the input into the collaboration the group from the Andrzej Sołtan Institute for Nuclear Studies undertook a task of investigating the validity of the design of a compact detector for Gamma Ray Bursts photon polarization measurements, known as POLAR. The authors focused at the scintillation and light transport properties of (200×6×6)mm3BC400 plastic bars as well as of other samples of BC408 plastic in the attempt to determine whether the assembled instrument is going to achieve the performance criteria bestowed upon it by the project. The investigation revealed a strong dependence between the amplitude of a signal and distance between the precursor interaction in a scintillator and the photodetector. Accordingly to this finding an attempt has been made to determine the influence of the surface polishing quality on the overall scintillator performance. The authors consider that proper machining of scintillator pieces, adequate choice of their packaging, and proper software analysis may overcome the revealed disadvantages.
