It has a feature of multihit readout, and it allows to read out temporal and pulse-height information of all of the hits. NewSFD x plane is now read out with this device. In 2008, newSFD planes were installed in the DIRAC spectrometer, and used in the physics experiment. We report in the present paper on the efficiency and the timing resolution of x plane read out using this new device. After applying the offl ine PSC algorithm, the efficiency of the plane was found to be 97.8% and the apparent multiplicity for the special events including 2 hits predicted with DC was about 4. The timing resolution of the plane was found to be 464.1 ps, thus it is much improved from 660 ps obtained using the LeCroy 3377 TDC. The F1-TDC-ADC is demostrated to be useful for the correction of the walk. Even a better timing result is expected after a better tuning of the VH., 4, KJ00005554119, P, 研究論文, Paper}, pages = {49--73}, title = {Read-out of the DIRAC newSFD using F1-TDC-ADC}, volume = {8}, year = {2009} }
