Runs

Date Run Number Comment
3/2/11 1795 D2O target first ToF attempt
3/2/11 1796 H2O target first ToF attempt Saw no difference with run 1795
3/2/11 1797 1/4" lead sheet target first ToF attempt
3/3/11 1801 Faraday Cup test with 200mA beam current
3/3/11 1802 Faraday Cup test with 100mA beam current
3/3/11 1804 Faraday cup test using 50mA beam current
3/3/11 1805 FC test collimating with Copper exposing bricks 16, 17, 18
3/3/11 1806 Faraday Cup test with small hole Al collimation
3/3/11 1807 Faraday Cup test with small hole Al collimation beam bent down (75A)
3/3/11 1808 Faraday cup test using 1/8" vertical slit collimation kicker magnet off
3/3/11 1809 Same as 1808 but with kicker magnet bending downward at 75A
3/3/11 1810 FC test increased beam current (~200mA) kicker off
3/3/11 1811 FC test with max possible beam current (~225mA) collimated with 4mm vertical slit via Al
3/3/11 1812 FC test re-run of 1811 to check for consistancy
3/3/11 1813 FC test with kicker magnet bending downward at 75A
3/3/11 1815 Lead Target ToF attempt, good looking gamma peak, need more stats
3/3/11 1816 Lead Target ToF attempt, cancelled due to multiple start pulse problem
3/3/11 1817 Lead target ToF with 314k events
3/3/11 1822 Radiator in, no target, 314k events, TDC spectrum looks the same as with lead target
3/3/11 1824 Radiator in, 2" lead brick as target
3/3/11 1826 Radiator out, 2" lead brick as target
3/3/11 1827 Radiator in, 1/2" Al slab at end of pair spec.
3/4/11 1831 25 MeV FC test, see scope picture #46
