都灵 Dipartimento di Fisica Sperimentale 和国家原子能研究所 (INFN) 与居里研究所 - 奥赛质子治疗中心 (CPO) 合作，开发并建造了一个像素平行板电离室，用作居里研究所 - CPO（法国奥赛）质子治疗束线的监视器。探测器的敏感面积为(160×160)mm2，阳极被分割成1024个方形像素，排列成32×32的矩阵；每个像素点的面积为(5×5)mm2。探测器被放置在最后一个准直器上游的光束线上，以监测光束形状并测量传输系统的稳定性和再现性。在本文中，我们详细描述了探测器以及一组初步测试的结果。
The Dipartimento di Fisica Sperimentale and the Istituto Nazionale di Fisica Nucleare (INFN), Torino, in collaboration with the Institut Curie—Centre de Protontherapie de Orsay (CPO), have developed and built a pixel parallel plate ionization chamber to be used as monitor for the proton therapy beam line at the Institut Curie—CPO (Orsay, France). The sensitive area of the detector is (160×160)mm2, with the anode segmented in 1024 square pixels arranged in a 32×32 matrix; the area of each pixel is (5×5)mm2. The detector has been placed on the beam line just upstream of the last collimator to monitor the beam shape and to measure the stability and reproducibility of the delivery system. In this paper, we present a detailed description of the detector and the results of a set of preliminary tests.
