ndash At solar scale you cannot see explicitly a e transition through CC production no natural or man-made source are beyond the kinematical threshold for production

ndash At the atmospheric scale you have powerful source but e transition are suppressed (ldquo13 dilemmardquo) We must resort to looking for taus

bull At long baseline (small m2) seeking for taus on an event-by-event basis is a major engeneering and experimental challenge

ndash It requires a beam O (10) more energetic than any other LBL

ndash It requires a fine grained far detector O (100) more massive than its short-baseline ancestors (kton-size)

OPERA is an hybrid detector built running in parallel with several ancillary facilities that - before 2008 ndash hadnrsquot been validated at nominal speed yet

Brick findingbull Use data from the real-time detectors (scint hits pe identified tracks in the

target and spectrometers) to build a probability map of the bricks where the interaction might have occurred

bull The most probable brick is extracted and the corresponding Changable Sheet is detatched and scanned

Conclusions

bull After a troublesome startup CNGS has delivered a significant integrated intensity in 2008 (~2 1019 pot) It represents the first real physics run for OPERA

bull The construction of OPERA is over the subdetectors and the ancillary facilities are fully operative

bull Already after 4 months from the end of CNGS data taking most of the analysis chain has been validated A crucial milestone for this experiment

bull We plan to complete the last steps (vertex and kinematic analysis of the full sample) in a few months - likely before the startup of 2009 run A lot of physics can be drawn from this sample Moreover 07 taus are waiting for us

bull What about 2009

Perspectives for 2009 are good Still only 35 of the nominal 451019 pot are expected this year Wersquore a small fish in the storm of the LHC startup but we appreciate the committment of CERN on the LBL programme at the same time we have the duty of keeping pressure on it for the success of the CNGS project
