Infrastructure status
HARDWARE:
MIC1: high magnification obj (100x)
MIC2, MIC3: currently working for scanning of OPERA events
MIC4: currently working for scanning of glued emulsions
MIC5: devoted to plate changer tuning (not glued emulsions) and for manual check
SOFTWARE:
- Computing infrastructure upgraded not to the the last release
- All data taking with ScanGrid now (3 servers currently installed and working)
-Local DB scheme upgraded to last one.

1 CS Prediction (not the muon)Prediction matched on plate 57 and scanback done Passing through track
TS done to look for muon candidate
The track is not related to the CC event but to a rock muon this brick should not be extracted.
Not connected(3CC without muon pred – 2 NC)
- : TX = -0.203 TY = 0.267
6 predictions received from LNGS (2 tracks seem duplicated-tracks), not the muon and not converging
Not matched From the electronic the bricks seems the right one rescan requested.

9 predictions from LNGS None matched!!!Maybe coming from a shower?
However we try to find the muon performing a TS around the point of convergence (IP ~ mm)from PL38 to PL42.
Muon candidate found passing through the volume: TX 0.305 TY 0.234
SCANBACK STARTED
7 predictions received from LNGS spreaded on the “whole” surface.

asked.

The muon candidate: manual check on all the segments to be done.
Volume analysis around the other stopping points to be done before requesting a new brick estraction.
SB done: muon candidate exits laterally
Event: 219015457 Brick: 1084486
- : TX = 0.052 TY = -0.003
5 predictions from LNGS: 2 seem to converge
First attempt: one track matched scanback started, stop PL 57.
GeneralScan 3 plates (57-55)
Mu candidate found (in the display below is the black track)
Stop: pl 46 TS done track isolated, shower hint.
Muon candidate seen as stop tracksent at LNGS: Not found.
Requested new check taking into account the offset found in the unique prediction matched in the brick.
