The European Extremely Large Telescope is set to be the foremost facility for ground based visible and near-infrared astronomy in the next decade. Proposed to be the world's largest telescope with a primary mirror diameter of 42 metres, the E-ELT will be able to study in detail the early Universe, peering far back to the epoch of formation of the first generation of galaxies. The E-ELT's impressive light gathering power and unsurpassed spatial resolution needs a suitably capable set of instruments to harness its scientific potential effectively. We propose to carry out a Phase A design study of one of the first light instruments for the E-ELT. In November 2007, ESO released a competitive 'Call for Proposals' for a Phase A study for a 'Single Field, Wide Band Spectrograph for the European Extremely Large Telescope'. The University of Oxford led a consortium (involving four other partner institutes) that responded to the call for proposals, and in mid-December, was chosen by ESO to carry out the study (from amongst several proposals by scientists from the ESO member states). HARMONI will be able to operate at several different spatial resolutions, ranging from coarse (assisted by GLAO) to fine (sampling the E-ELT's diffraction limit at near-infrared wavelengths). It will cover the near infrared wavelength range at a spectral resolving power of about 4000, both shorter wavelength coverage and higher spectral resolution extensions will also be considered, as will be a simple coronagraphic mode. The Phase A study will consist of two Phases. In the first phase, we will carry out a trade-off study for the parameters that define the technical specifications of the instrument, such as field of view, spatial sampling, spectral resolution, simultaneous spectral coverage. A science team composed of researchers from the ESO member states, who are keen to carry out scientific programs with HARMONI, will assist in this task. Phase 2 will consist of using the results of the trade-off study to build a conceptual design for HARMONI, including an opto-mechanical concept. This will require close collaboration with ESO to define the interfaces with both the adaptive optics system and the telescope.

欧洲极大望远镜将成为未来十年地基可见光和近红外天文学的最重要设施。E-ELT被提议成为世界上最大的望远镜，主镜直径为42米，将能够详细研究早期宇宙，可以追溯到第一代星系形成的时代。E-ELT令人印象深刻的聚光能力和无与伦比的空间分辨率需要一套适当的仪器来有效地利用其科学潜力。我们建议为英语教学的首批轻型仪器之一进行A阶段设计研究。2007年11月，欧洲南方天文台发布了一份竞争性的“提案征集”，以进行“欧洲超大望远镜单视场宽带摄谱仪”的A阶段研究。牛津大学领导了一个联盟（包括其他四个合作机构），该联盟响应了提案的呼吁，并于12月中旬被ESO选择进行研究（来自ESO成员国的科学家的几个提案）。HARMONI将能够在几种不同的空间分辨率下工作，从粗（由GLAO辅助）到细（在近红外波长处对E-ELT的衍射极限进行采样）。它将以约4000的光谱分辨率覆盖近红外波长范围，也将考虑更短的波长覆盖和更高的光谱分辨率扩展，这将是一个简单的日冕模式。A期研究将包括两个阶段。在第一阶段，我们将对定义仪器技术规格的参数进行权衡研究，如视场，空间采样，光谱分辨率，同时光谱覆盖范围。一个由ESO成员国的研究人员组成的科学团队将协助这项任务，他们热衷于与HARMONI一起开展科学项目。第2阶段将包括使用权衡研究的结果来构建HARMONI的概念设计，包括光机械概念。这将需要与ESO密切合作，以确定自适应光学系统和望远镜的接口。
