GRAINE(带核乳胶的伽马射线天文成像仪)项目的目的是使用气球载乳胶探测器精确观测宇宙伽马射线。飞行中发生的所有现象都记录在乳胶中，不仅研究伽马射线事件，而且研究初级宇宙射线包含的强子相互作用事件，这是很有趣的。尤其是对高空初级宇宙线相互作用中魅力粒子产生的研究是本文的主要兴趣所在，因为这些信息对于验证瞬发中微子(大气中微子)通量是很重要的，因为它们大多是魅力粒子的衰变产物。通过使用自动乳胶读出系统HTS(超径迹选择器)，可以读出乳胶中记录的所有径迹，并分析所有强子相互作用，以寻找迷人的粒子衰变。
本文介绍了用CERN加速器束流进行的初步试验结果。在这次试验中，检验了一种通过自动分析来估计初级宇宙线能量的方法。
The purpose of GRAINE (Gamma-Ray Astro-Imager with Nuclear Emulsion) project is precise observation of cosmic gamma-ray by using a balloon-borne emulsion detector. All phenomena occured in flight are reccorded in emulsion and it is interesting to study not only gamma-ray events but also hadron interaction events incuded by primary cosmic rays. Especially study of charmed particle production in primary cosmic rays interactions at high altitude is major interest of this article, since this information is important to validate prompt neutrino ( atmospheric neutrino ) flux as most of them are decay products of charmed particles. By using automated emulsion readout system HTS ( Hyper Track Selector ), it is possible to readout all tracks recorded in emulsion and analyze all hadron interactions to search for charmed particle decays.
This article describes a preliminary results of a test experiment using CERN accelertor beam. A method to estimate energy of primary cosmic rays by an automated analysis is checked in this test.
