On the small blue screen you will see 4 channels. Write down tyhe numbers for ch0, ch2, ch3. Ch1 is off</p> <p>3. collect one fast file and check with nearline if 60Ni is indeed the beam. In You should see 1333 keV line in the Compton clean spectrum. See attached</p> <p>4. Check the DSSD spectrum. It should not change - to do this select "DSSD spectra each channel" histogram and project one channel, and compare with run_37 (the first one after restoring tandem)</p> <p>5. Check the current (between 20 and 40 enA)</p> <p>6. run nearline with all files - 37-current,excluding run 41</p> <p>7. fill out the google spreadsheet - the hours should correspond to what is stored on the disk so put in the real time, not the daq time</p> <p>8. in workspace 2 there are 2 terminals. Please after stopping the run do the rsync of raw data and nearline</p></td> </tr> </tbody> </table> </p><p> </p> Encoding: HTML ELCode plain Suppress Email notification
