Abstract: (IOP)
The barrel time-of-flight (TOF) detector for theANDA experiment at FAIR in Darmstadt is plannedas a scintillator tile hodoscope (SciTil) using 8000 smallscintillator tiles. It will provide fast event timing for a softwaretrigger in the otherwise trigger-less data acquisition scheme ofANDA, relative timing in a multiple track eventtopology as well as additional particle identification in the lowmomentum region. The goal is to achieve a time resolution ofσ 100 ps. We have conducted measurements using organicscintillators coupled to Silicon Photomultipliers (SiPM). The resultsare encouraging such that we are confident to reach the requiredsystem time resolution.
