ULTRACAM is a digital camera capable of taking (and storing) up to 500 red, green and blue images per second. The instrument was built in just under 3 years by a consortium from the Universities of Sheffield, Warwick and the UK Astronomy Technology Centre in Edinburgh, using a £300,000 grant awarded by PPARC. ULTRACAM saw 'first light' on 16 May 2002 on the 4.2-m William Herschel Telescope (WHT) on La Palma, and first light on the 8.2-m Very Large Telescope (VLT) in Chile on 4 May 2005. This latter telescope is currently the world's largest and ULTRACAM became both the first instrument to make use of its new 'Visitor Focus' and the first UK-built instrument to be mounted (at any focus) on the VLT. To date, ULTRACAM has been awarded a total of 87 nights on the WHT and 23 nights on the VLT for projects in many different areas of astrophysics, including the study of white dwarfs, brown dwarfs, red dwarfs, pulsars, black-hole/neutron-star X-ray binaries, gamma-ray bursts, cataclysmic variables, eclipsing binary stars, extrasolar planets, active galactic nuclei and occultations by Solar System objects (Titan, Pluto and Kuiper Belt objects). Since ULTRACAM is a private instrument, the ULTRACAM team at Sheffield are responsible for the installation and removal of the instrument as well as for the observations with it. This means that the ULTRACAM team have had to spend approximately 200 nights at the WHT and VLT over the past 4 years. Dhillon (the ULTRACAM PI) has been finding it increasingly difficult to meet this demand for time on ULTRACAM and balance it against the time required to fully exploit the unique scientific datasets which have been/will be obtained and the continued maintenance and enhancements required to keep the instrument at the forefront of its field. This grant therefore requests funding to enable Dhillon to devote all of his time to the ULTRACAM project for the next 3 years. The grant also requests continued funding for Littlefair, the ULTRACAM PDRA at Sheffield, who is now a fully-trained, invaluable member of the team who is leading two major ULTRACAM research projects.

Ultracam是一款数码相机，每秒可采用（并存储）500个红色，绿色和蓝色图像。该乐器是由Sheffield大学，沃里克大学和爱丁堡英国天文技术中心的一家财团在不到3年的不到3年中建造的，使用了PPARC授予的300,000英镑赠款。 Ultracam于2002年5月16日在La Palma上的4.2-M William Herschel望远镜（WHT）上看到了“第一灯”，并于2005年5月4日在智利的8.2毫米非常大的望远镜（VLT）上首次亮相。这款最新望远镜目前是世界上最大的工具，也是首次使用其新的'uniunt of the ukirt of in Ukirt of the New'Vistor''''Vistor''' VLT。迄今为止，由于Ultracam是一种私人乐器，Sheffield的Ultracam团队负责Sheffield的Ultracam团队负责该乐器的安装和拆除以及与IT的观察，因此Sheffield的Ultracam Team负责Sheffield的Ultracam Team，Sheffield负责Sheffield的Ultracam Team，Sheffield的Ultracam团队负责Sheffield的Ultracam Team，在许多不同的项目中，UltraCam在VLT上总共获得了87晚和23晚的授予。这意味着在过去的4年中，Ultracam团队不得不在WHT和VLT上度过大约200个晚上。 Dhillon（Ultracam Pi）一直发现，满足UltraCAM的时间的需求越来越困难，并平衡它与将获得/将要获得的独特科学数据集所需的时间以及将仪器保持在其领域的最前沿所需的持续维护和增强。因此，这笔赠款要求资金使Dhillon在未来3年内将所有时间都花在Ultracam项目上。该赠款还要求继续为Sheffield的Ultracam PDRA Littlefair提供资金，他现在是该团队中训练有素，宝贵的成员，领导了两个主要的UltraCam研究项目。
