Photoproduction Background

6m Tagger egrave un rivelatore posto a 537 m dal punto di interazione egrave stato installato nel 2001 per misurare elettroni per gli eventi Bethe-Heitler

Ha unrsquoaccettanza prossima al 100 per elettroni diffusi in eventi Bethe-Heitler (fotoproduzione) in una ristretta finestra di energia (~ GeV)Il range di energia accettata dipende dalla posizione del fascio e dallrsquoeffetto dei magneti prossimi al punto drsquointerazione e utilizzando fasci di e+ si puograve accedere a energie piugrave basse dellrsquoe diffuso

Il 6m Tagger egrave un componente determinante per capire il fondo di fotoproduzione nel campione ad alto y e per stimare il fattore di normalizzazione da assegnare al PHP MC
