Sorry this is so late - I want to get it out before the next weekly tuesday meeting. Summary of meeting 4/20/00 Present: Rusack, Gollwitzer, Graham, Seo, Negrini, Stancari(M), Stancari(G). Pordes, Obertino, Garzoglio, Baldini, Cibinetto, Kasper, Hu Stack was lost due to power outage..see shift report 4/20 day.. Giulio said that a possible reason for the periodic small beam losses was the process that was being used to monitor the orbit frequency and rebunch the beam at that exact frequency (x ?) to help the BPM's. This process affects the beam (a little) and can get into a fight with the cooling. Since the process has been turned off, the losses have not recurred and the BPM's don't seem to mind. Martin added that the larger beam losses that had occurred sporadically during the recent thunderstorms seemed to be correlated with the Zeus 1 and Zeus 2 signal monitors. Giulio reported that he has developed a procedure that adds all the frequency spectra of a run to give the actual momentum spectrum of the beam and uses this spectrum explicitly in the likelihood fit of the excitation curves. He has done this for the chi-0 data - and gets answers very similar to Nadia. He will next do the psi' where we have this apparent discrepancy with E760 (added since: see also note from Seth re resolving this discrepancy). Martin asked about the spikes one occasionally sees in the Ecm plot online. These may be due to BPM resets/glitches. There was some discussion about the energy of the next stack. After some considerations, it was agreed to stick to 3416. (note added: the rest is history.) Stephen
