The magnetic rigidity ("Brho") of BTS 32 & 33 ([[Introduction#Analysis Line|analysis beam line]]) of the S800 page will be set during the secondary-beam tuning (SDT) in cooperation with the AP/ARIS team. 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 ARIS, 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 AP/ARIS team 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 BTS 32 & 33 ([[Introduction#Analysis Line|analysis beam line]]) of the S800 page will be set during the secondary-beam tuning (SDT) in cooperation with the AP/ARIS team.

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, BTS34 Brho and the magnet currents of the dipoles and quadrupoles are needed to determine important input parameters for the calculation. | We strongly recommend savesets (formerly known as Barney printouts) after every change of the spectrograph.
