MALT（东京大学串列加速器微量分析实验室）是一个使用串列加速器进行元素和同位素微量分析的服务和研究设施，建于1991-1993年，自1994年以来一直在运行。从那时起，AM S，NRA和PINE系统已经开发并高度完善。MALT的加速器是5 UD Pelletron（TM）串联货车de Graaf（由美国国家静电公司生产），并且最大可获得5 MV电压。MALT配备了两个MC-SNICS离子源（其中一个专用于C-14-AMS）、顺序注入系统和多法拉第杯系统。这些设备都是高精度、高效率AMS系统不可缺少的组成部分，MALT已生产出Be-7、Be-10、C-14、Al-26等高质量的AMS。最近，使用充气磁体的Cl-36 -AMS系统也得到了极大的改进，并且开发了一种新的I-129-AMS系统，表现出良好的性能。目前，MALT是亚洲地区唯一的多核素AMS装置，每年有40多个项目在运行。2004年总加速器运行时间为6363 h。2004年11月，自MALT建成以来，pelletron链系统的总运行时间超过40，000小时，无需更换。(c)2007 Elsevier B.

MALT (Micro Analysis Laboratory, Tandem accelerator, The University of Tokyo) is a service and research facility for elemental and isotopic micro-analysis using a tandem accelerator, which was constructed in 1991-1993 and has been in operation since 1994. Since then, AM S, NRA and PINE systems have been developed and highly refined. The accelerator of MALT is a 5UD Pelletron (TM) tandem van de Graaf (produced by National Electrostatics Corporation, USA) and maximum 5 MV voltage is available. MALT is equipped with two MC-SNICS ion sources (one of them dedicated for C-14-AMS), a sequential injection system and multi-Faraday cup systems. These equipment are all indispensable for a high precision and high efficiency AMS system.At MALT, high quality AMS of Be-7, Be-10, C-14, Al-26 has been available. Recently, a Cl-36 -AMS system using a gas-filled magnet was also greatly refined, and a new I-129-AMS system was developed and shows good performance. Now MALT is the only facility with multi-nuclide AMS in the Asian area.Over 40 projects are running at MALT every year. The total accelerator operation time in the 2004 season was 6363 h. In November 2004, the total operation time of the pelletron chain system since the construction of MALT went over 40,000 h without replacement. (c) 2007 Elsevier B.V. All rights reserved.
