Résumé

New methods for efficient and unambiguous interconnection between electronic position sensitive detectors and target units based on nuclear photographic emulsion films have been developed. The application to the OPERA experiment,that aims at detecting V_μ⇋V_τoscillations in the CNGS neutrino beam,is reported in this paper. In order to reduce background due to latent tracks collected before installation in the detector,on-site large-scale treatments of the emulsions (“refreshing”) have been applied. Changeable Sheet (CSd) packages,each made of a doublet of emulsion films,have been designed,assembled and coupled to the OPERA target units (“ECC bricks”). A device has been built to print X-ray spots for accurate interconnection both within the CSd and between the CSd and the related ECC brick. Sample emulsion films have been extensively scanned with state-of-the-art automated optical microscopes. Efficient track-matching and powerful background rejection have been achieved in tests with electronically tagged penetrating muons. Further improvement of in-doublet film alignment was obtained by matching the pattern of low-energy electron tracks. The commissioning of the overall OPERA alignment procedure is in progress.

N2 - New methods for efficient and unambiguous interconnection between electronic position sensitive detectors and target units based on nuclear photographic emulsion films have been developed. The application to the OPERA experiment,that aims at detecting Vμ⇋Vτoscillations in the CNGS neutrino beam,is reported in this paper. In order to reduce background due to latent tracks collected before installation in the detector,on-site large-scale treatments of the emulsions (“refreshing”) have been applied. Changeable Sheet (CSd) packages,each made of a doublet of emulsion films,have been designed,assembled and coupled to the OPERA target units (“ECC bricks”). A device has been built to print X-ray spots for accurate interconnection both within the CSd and between the CSd and the related ECC brick. Sample emulsion films have been extensively scanned with state-of-the-art automated optical microscopes. Efficient track-matching and powerful background rejection have been achieved in tests with electronically tagged penetrating muons. Further improvement of in-doublet film alignment was obtained by matching the pattern of low-energy electron tracks. The commissioning of the overall OPERA alignment procedure is in progress.
