- Status: beam tuning was fast, quickly verified CU position and steered beam in place; collected ~250Kevents at 0 degree and 30 degree; beam rate varied at 0 degree; Francesco is working on updating the pipeline with new TkrRecon but some issues with new BTRelease must worked out with Michael - hope to have it by tonight; Fabio setup the remote control for Benoit scope in order to measure the cristal signal from the control room
- Program: see here for details ; indications show no rate effect at the highest rate we ran (200Hz) (Thierry), so we decide to use those settings for the rest of the run; comparison with 2003 results show no changes for quenching factors (Thierry), so we decide not to have dedicated run on tower1 as originally forseen for that purpose; will use the night for Xe as fragment production with target requires longer runs which are suited for night-time operation; luca, carmelo and sandro will stay until 4AM, luca B and johan will come back at 4AM to complete the night program; tomorrow we will perform dedicated runs (charge injection with beam on, scintillation measurement, energy scan) and complete statistics with C working on more angles or more events per same configuration
- Preliminary results (also posted on the program : Thierry showed consistency with 2003 results (quenching) and no rate effect for CAL; Leon showed cluster analysis in TKR that indicates 5.7 average cluster width; statistics is currently limited by older version of TkrRecon which assigns 1st track to delta rays and not to C ions - need to repeat analysis and evaluate required statistics per configuration when new TkrRecon will run in the pipeline
