We have studied counter sizes up to $120\\times40\\times5$ mm^3 with series connection of multiple SiPMs to increase the sensitive area and thus achieve better time resolution. A readout scheme with analog shaping and digital waveform analysis is optimized to achieve the highest time resolution. The timing performance is measured using electrons from a Sr-90 radioacti","authors_text":"Flavio Gatti, Massimo Rossella, Matteo De Gerone, Miki Nishimura, Paolo W.
