Beam position was scanned from -9 and -4. Attachment 1 shows the maximum in count rate around the -7.5 position. </p> <p>Second optimisation procedure was to change the time ions are allowed to circulate in the ring before being dumped. The count rate over 5 minutes in detector #0 (top left) at ~20 MeV was used as a gauge. This is the only part of the cycle we can control.</p> <p>Time (s) Counts</p> <p>2 148</p> <p>3 200</p> <p>4 178</p></td> </tr> </tbody> </table> </p><p> </p>
