Date: June 18, 2004Re: Testing and analysis of beam data
The SRCH (Solenoid Radial Calorimetric Hodoscope) collaboration has started data collection again after recent upgrades at the Electron/Positron Collider Facility. There are two teams independently analyzing the early data: the Orange Team and the Blue Team. This affords us a unique opportunity for confirmation of results.
In order to understand the performance of the detector during the colliding beam run, we have provided test beam data collected earlier this year. The detector is comprised of three major subsystems: ECal (electromagnetic calorimetry), HCal (hadronic calorimetry) and SiDet (silicon detector).
Each team should form smaller working groups to calibrate these major subsystems. The Working Groups will calibrate their systems by using data collected with test beams comprised of known particles at known energies. The teams will then use these calibration results to identify and study unknown particles produced during the colliding beam runs.
Please continue to refer to the project milestones as you work. We will visit your team during your milestone seminars during the week. We all look forward to learning about your discoveries and insights this Friday at the all-hands conference.
Finally, we would also like to take this opportunity to announce the completion of our resources library focusing on the following topics: relationships among energy, momentum and mass, conservation laws, and the behavior of charged particles in magnetic fields. The resources also include diagrams of the detector and its geometry.
