=== Segments 6 and 7 (S800 Analysis line) === | === Segments 6 and 7 (S800 Analysis line) === |
The magnetic rigidity ("Brho") of the segments 6 and 7 ([[Introduction#Analysis Line|analysis beam line]]) of the S800 Barney page displayed below will be set during the secondary-beam tuning (SDT) in cooperation with the [[https://groups.nscl.msu.edu/a1900|A1900 group]]. The energy loss in all detector systems ([[Detectors#Plastic scintillators|object scintillator]], object PIN, [[Detectors#Tracking Parallel Plate Avalanche Counters (TPPAC)|tracking PPACs]]) operating in the [[Introduction#Analysis Line|analysis beam line]] has to be considered for the Brho setting. This requires the knowledge of the beam Brho at the exit of the [[https://groups.nscl.msu.edu/a1900|A1900]], which is typically calculated with the program [[http://lise.nscl.msu.edu/lise.html|LISE++]] (follow this [[https://groups.nscl.msu.edu/a1900/software/lise++/|instructions]] and/or ask the [[https://groups.nscl.msu.edu/a1900|A1900 group]] for assistance). In the course of secondary-beam tuning, a scintillating target ("viewer") and camera setup at the target position of the S800 might be requested by the [[https://groups.nscl.msu.edu/a1900|A1900 group]]. | The magnetic rigidity ("Brho") of segments 6 and 7 ([[Introduction#Analysis Line|analysis beam line]]) of the S800 Barney page displayed below will be set during the secondary-beam tuning (SDT) in cooperation with the [[https://groups.nscl.msu.edu/a1900|A1900 group]].

We strongly recommend Barney printouts after every change of the spectrograph. This not only provides a paper copy of all magnet settings from segment 0 to segment 8 but also saves this information in ascii format on disk (accessible via the A1900 web site under [[https://groups.nscl.msu.edu/a1900/archive/barney/|Beam Line Savesets]]). If an [[Determination of Angles and Momentum#Calculation of the inverse map|inverse map]] is desired for the tracking of the particles in the spectrograph, segment 8 Brho and the magnet currents of the dipoles and quadrupoles are needed to determine important input parameters for the calculation. | We strongly recommend Barney printouts after every change of the spectrograph.
