Series II: Columbia Radiation Laboratory
Series VI: Physics Research
This series, spanning record cartons 29–35, collects together research materials from the Physics Department not connected to one of the affiliated research laboratories. Many of these materials seem to have been the research files of Professor Emerita Wu and her associates.
This series contains three main groups of files. The first main group (folders 29.26–30.36) consists of lose-leaf laboratory notes foldered by research subject and organized alphabetically. For example, folder 29.38, "Cu64 Research," contains notes, charts and tables of figures related to research on Cu64.
The second main group (folders 30.37–32.13) consists of paper and cloth bound lab notebooks similar to those described in sub-series II-c. The first nine of these (all cloth bound) belonged to Professor Wu herself, and date from 1944–1954. The next fourteen belonged to named associates of Wu, and are sorted alphabetically by the name of the owner. Some of these are additionally given topical titles, as for example "Beta Ray Spectroscopy." The remaining dozen were also owned by Wu associates, but were not labeled with the owner's name. Some of these are titled, as for example "He3, d Reaction," but some are not.
The third and largest group of folders in this series (folders 32.14–35.8) consists of a lengthy set of "diagram files." These "diagrams" are blueprints, tables, graphs, flow charts, electrical schematics, and so on. The diagrams are often labeled, but only sporadically dated. Each of diagram is stamped "Columbia University Nuclear Physics Research" and assigned a "DWG. NO." The diagrams number (with some gaps) from 1197 to 5581; the number order is only very loosely chronological. Representative diagrams (from folder 33.2) are "Graph-H. Brown," "Temp'y El. Storage Sys.," "Gas Handling Schematic Layout." There is no obvious connection between the diagrams (except that they were all presumably produced for the Physics Department), and there is no general index or other supporting material for the collection of diagrams.
