Title: high light yield in a 1 liter liquid argon chamber read-out by
   SiPMs
Abstract content
We will show the results obtained with a liquid argon scintillation chamber with light read-out completely based on SiPM. We used a PTFE chamber containing about one liter of  liquid argon lined-up with a reflective foil (3M VIKUITI) evaporated with a wavelength shifter (TetraPhenyl Butadiene - TPB). The chamber is observed by  a small  array of 7 large area SiPM (Hamamatsu S11828-‐3344M, 1.7 cm2 each )  for a  coverage of the  internal surface of the order of 4%. The measured light yield is comparable with the highest light yield values obtained, in similar conditions, using a light detection system based on a standard 3" cryogenic PMT (Hmamatsu R11065) that allows for a photo-catodic  coverage 3 times  higher. This is an extremely important result that shows that at this moment SiPMs represent a real alternative to standard photo-multipliers for cryogenic noble liquids applications.
