  1. Scanning Report from Salerno • Brick scanning overview • Event gallery • General statistics • Conclusions

  2. Brick scanning summary * Brick 5969 is a NC with black CS. 1 track found, but passes through the brick. ** Brick 134936 has a secondary interaction of a NC event; parent track followed to plate 1

  3. Event gallery Event gallery

  4. Event gallery Event 224778801 Brick 150194 (fog ≃14grs/1000 mm3)

  5. Event gallery Event 224778801 Brick 150194 (fog ≃14grs/1000 mm3) Hint for shower in the CS candidates Human-assisted TotalScan, plates 5722: 1 cm2 around shower axis,reconstruct every 10 plates, check for shower/vertex

  6. Event gallery Event 224778801 Brick 150194 (fog ≃14grs/1000 mm3) Vertex found between plates 35 and 36 XY XZ

  7. Event gallery Event 224778801 Brick 150194 (fog ≃14grs/1000 mm3) Vertex found between plates 35 and 36 Two showers found (p0 is likely) Tilted XY

  8. Event gallery Event 237882171 Brick 134936 – NC, passing through with secondary

  9. Event gallery Event 237882171 Brick 134936 – NC, passing through with secondary YZ The twopassing-through tracks do not converge (seen on XZ) 3-prong vertex with primary Another passing-through XZ

  10. Event gallery Event 234925885 Brick 143527

  11. Event gallery Event 234925885 Brick 143527 YZ Track stoppingin the volumedownstreamof the vertex, not seen on CS XY Close-up

  12. Event gallery Event 234925885 Brick 143527 Track stoppingin the volumedownstreamof the vertex, not seen on CSIP = 80.5 mm DZ = 1900 mm CS check needed Tilted view

  13. General Statistics General Statistics

  14. General Statistics: Vertex features Charged multiplicity of CC primary vertices Charged multiplicity of NC primary vertices Average multiplicity: 3.6 QE-like: 9/44 = 20% Average multiplicity: 3.6

  15. General Statistics: Vertex features Muon impact parameter Hadron impact parameter Average IP: 2.8 mm Average IP: 12.0 mm

  16. General Statistics: Vertex features m f Azimuthal angle in nm frame between muon and hadrons nm h f, degrees Clear anti-correlation between muon and hadron directions

  17. Conclusions Scanning stopped for Christmas holidays, restarted smoothly Event statistics increasing steadily Running parameters stable since several months(No brick-by-brick tuning)
