1. HPS status

  • HPS finally started production, running around 11kHz and 150MB/s with 160nA current, rate may go up but not significantly which will be easy for DAQ; SVT part seems stable after a lot of work conducted during last few weeks by SLAC teem; rcdb was deployed last night, now all components are in place
  • more trigger studies can be conducted, beam current will be increased factor 2 so we need to optimize trigger to stay within about 30kHz event rate; random trigger run will betaken and studies conducted, in a meanwhile will used current trigger (single positron)
  • target beam current is 300nA, will try to do it soon
  • online reconstruction will be deployed
