Collaborative Meeting Notes (1.25 linear ft.) is arranged chronologically and includes agendas, data and data analysis, and making decisions. Meetings were held 3-4 times a year, from 1983 to 1990. Meetings to organize the IMB collaboration and experiments are recorded from 1979 to 1982. Also included is Professor van der Velde's notebook from PDK meetings, 1981-1984, with his notes and calculations.
Student Theses consists of nine theses written by students from research connected with IMB, from 1983 to 1990. Most theses focus on nucleon decay or the detection of neutrinos.
Talks (0.25 linear ft.) consists of notes and publications used to prepare for giving talks related to the IMB experiment results, some typed copies of the talks given, and photocopies of transparencies used for the presentations. Some talks were given by Professor van der Velde, and others by other members of the IMB collaboration. They cover four major speech topics: review of experiments, monopoles, neutrinos, and the supernova. Talks were given every few years, from 1980 to 1989.
Publications (0.5 linear ft.) includes papers written by collaboration members and by other scientists on related subjects, as well as data and calculations. Publications may be in draft or published form. Some have several drafts with collaboration critiques. Also included is the debate over a paper published by a collaboration member without approval. Papers focus on proton decay or neutrinos detected from the supernova. There are also a memo listing all the papers produced by the collaboration up to 1990, a 1991 interview of Professor van der Velde for a study on collaborations in high-energy physics, and the 1989 talk given by co-spokesperson F. Reines accepting the Rossi prize at the AAS meeting on behalf of the collaboration.
Proposals (0.25 linear ft.) covers both plans for future experiments and funding and equipment proposals. It includes the original experiment proposal. The series also includes a report on the progress of construction from April 1981 and an evaluation of the project by TACUP (Technical Assessment Committee of University Programs) from 1983.
Research Notes and Memos (0.5 linear ft.) includes data print outs, data analysis and calculations, and memos between collaboration members as they determine the meaning of the data. Also included is a chronology of the University of Michigan's involvement with the IMB collaboration. There are nine slides of the construction of the detector and 21 slides of experiment results, and a photograph of Professor van der Velde standing on top of the IMB pool.
