项目摘要

People have been so keen at proceeding the project of raising the brilliance of synchrotron radiation in these, say, twenty years.Its rapid growth is quite amazing.That is almost equivalent to two orders of magnitude of brilliance every three years.That number is likely going to reach almost 10^<20> in unit of brilliance.Not only pursuing this direction but also trying to develop other new property such as coherence will surely be a key to open up a new world such as x-ray holography.For that purpose more than a few laboratories such as SLAC,UCLA in US and DESY in Germany seem to start to push very hard these project.Right now there seem to exist at least two ways to develop coherent radiation sources : one is to develop storage rings and the other linacs.It is hardly possible to judge which will achieve the goal easier and quicker.It also strongly depends on the wavelength one is concerned about.In order to proceed our project in which we like to focus especially on x-ray domain we have first sent two members to Russia last summer to have surveys and further invited not only members but also cooperative researchers from overseas countries to have discussion on this issue.So far we could have exchanged a plenty of and quite fruitful results so that we will be able to evaluate what to do with this project in the near future.

人们热衷于提高同步辐射亮度的工程近二十年了。它的增长速度是相当惊人的。这几乎相当于每三年亮度增加两个数量级。这个数字是有可能的。以亮度为单位将达到近10^<20>。不仅追求这个方向，而且尝试开发其他新特性，例如相干性，必将成为打开X射线等新世界的关键为此，美国的 SLAC、UCLA 和德国的 DESY 等多家实验室似乎开始大力推动这些项目。目前似乎至少存在两种方法来开发相干辐射源：一是开发存储环和其他直线加速器。很难判断哪个会更容易、更快地实现目标。这也很大程度上取决于人们所关心的波长。为了继续我们的项目，我们特别喜欢关注x -射线域我们首先有去年夏天，我们派了两名会员到俄罗斯进行了调查，并进一步邀请了会员以及海外的合作研究人员就这个问题进行了讨论。到目前为止，我们已经交流了很多、非常富有成效的成果，使我们能够评估在不久的将来如何处理该项目。
