Hi Everyone, Following up on Takashi's email, for those who are ready to analyze the data now: Tonight's data taking is 10nA on target with a very loose pairs trigger (basically just ~10 MeV crystal threshold) at a rate of few kHz along with a 1 kHz random pulser. There is a log entry with some details here (and a run spreadsheet is being filled in the counting house, to be posted): https://logbooks.jlab.org/entry/3313255 See more recent logbook entries here: https://logbooks.jlab.org/book/hblog We are nominally doing 2-hour runs, and the runs are being copied to tape: /mss/hallb/hps/data And also to disk for easy access: /cache/mss/hallb/hps/data /volatile/hallb/hps/data/tgt Let me know if you can't get to the data! -Nathan On Dec 12, 2014, at 8:39 PM, "Maruyama, Takashi" <[log in to unmask]> wrote: > > With heroic effort by Stepan, the anomalous source of background was identified and eliminated completely. 1.5 micron-thick Pt target was inserted.
