Tandem Pictures Available
We have just acquired a digital camera and have taken some pictures of the Tandem Facility that may be of interest. The camera has a 5 Megapixel sensor and the file sizes are quite large. We have shrunk the files to a manageable size by decreasing the image size and the color depth. The resulting files are several hundred KB and the quality is quite good. To take a look go to Pictures.

Roy Middleton's 'Negative Ion Cookbook' is available on the web. It explains how to make negative ions of almost any element. To take a look at it go to Cookbook.
