摘　　要：介绍了一个新的中子飞行时间斩波器谱仪HRMECS的数据处理工具JavaCAP。JavaCAP充分利用了Java语言的平台独立性和因特网适用性两个独特的优点 ,以及面向对象的编程手段 ,克服了原有FORTRAN版的局限性 ,重新开发了一系列新的功能。目前 ,JavaCAP已纳入ISAW (integratedspectralanalysisworkbench)中 ,成为ISAW第一个具有数据处理功能的工具软件包。A software application for analyzing time of flight data obtained from chopper spectrometer is introduced. This chop analysis package, JavaCAP, is written in Java to take advantage of its platform independence and internet accessibility. Multiple large datasets, each containing about 1 000 spectra, can be examined for removal of noise and contamination. Appropriate sample, background and calibration runs are combined and normalized. Afterward, data from detector groups are binned and converted into various scattering functions in momentum and energy transfer space. The resulting datasets can be analyzed further by users with additional methods. The results can also be saved as formatted tables in text files or pasted into other applications.
