Stefan Institute) Place : KEK Tsukuba campus 4th building seminar hall + Zoom Abstract: LAPPD (Large Area Picosecond Photon Detector) is a large MCP-PMT with a large active area of about 20 cm x 20 cm. It is a promising candidate for an upgrade of the Belle II ARICH detector, a proximity-focusing RICH with a two-layer (focusing) aerogel. Generation II LAPPD with a capacitively coupled sensing electrode was bench tested with a picosecond laser to evaluate its properties. The main focus was on the time and position resolution, and the spread of the induced charge on the sensing electrode. We will discuss the properties of the LAPPD and the results of the tests. https://kds.kek.jp/event/46822/ Zoomによるリモート接続は下記URLとなります。 https://us02web.zoom.us/j/84377834918?pwd=QkRSK3RLUzJUK3p5dldyUHlGbXZwZz09 Meeting ID: 843 7783 4918 Passcode: 791934 セミナーは英語での開催となります。どなたさまも参加は自由ですので 是非奮ってご参加下さい。また関係者への周知をよろしくお願いいたします。 皆様のご参加をお待ちしております。 測定器開発センターセミナー係 坂下 and 素核研セミナー委員 松原・石川 --- Dear all, This is an announcement of the KEK IPNS+ITDC Detector Seminar, which will be held on 16:00 - 17:00, June 14 (Wednesday): Title:  Recent studies of Large Area Picosecond Photon Detector Speaker: Prof. Samo Korpar (University of Maribor and J.
