D507700100015 FACILITY (SYNCH,2GERJUL) The COSY COoler SYnchrotron of the D507700100016 Forschungszentrum Juelich D507700100017 DETECTOR (MWDC) The Forward Detector consists of two multiwire D507700100018 proportional chambers, one drift chamber, and three D507700100019 layers of scintillation hodoscopes. D507700100020 MONITOR (1-H-2(P,EL)1-H-2,,DA)The luminosity required to D507700100021 determine cross sections was found by simultaneously D507700100022 measuring dp elastic scattering, with the scattered D507700100023 deuterons being registered in the forward detector and D507700100024 the proton reconstructed from the missing mass. D507700100025 ERR-ANALYS (ERR-T) Total uncertainty D507700100026 (ERR-SYS) The systematic uncertainty in the measurementD507700100027 of the deuteron angle thus dominates the error of aboutD507700100028 +-15% in the luminosity determination. However, the D507700100029 relative luminosity over the ramp is known much better D507700100030 and its effects are included in the point-by-point D507700100031 errors.
