This is a summary of beam Cherenkov pressure curves with nitrogen. Shaded areas for each particle species are between threshold density and density at which Cherenkov angle is 5mrad. Superimposed data are centers of peaks in pressure curves. Error bars in y are sigma's of Gaussian fits. Error bars in x are 3% of the momentum. [lebedev@physics.harvard.edu] BCkov_pcurve_log [eps]

./NuMI/
NuMI.Radiograph.Align.Annotated [eps]
[png]
Cross-section radiograph of the NuMI target. z-scale is (N(interaction)-N(no interaction))/N(total), and is therefore related to the density of the material. Plot generated using the pass4aii DSTs, and (x,y) coordinates are the position of the reconstructed beam track at the upstream end of the target. Data used is mostly from runs when the 120 GeV beam was being tuned. The black circle represents the beam profile for the 2mm trigger, and the cross hairs represent the center of the graphite slabs in the target. Both the beam profile and center of graphite are determined from the data. In this version, the main features of the target are annotated. jpaley@indiana.edu NuMI.Radiograph.Align [eps]

triggerPurityWithRiCHRings [eps]
[png]
This is the online trigger purity as measured with the RICH rings for a number of runs with various momenta. For momenta above 30 GeV/c, kaon purity is low when beam Cherenkov is set incorrectly. For low momenta, proton purity is low because pions create a lot of light and confuse the trigger. [lebedev@physics.harvard.edu]
