CCMR has useful facilities all over campus, and grad students can usually use their services and equipment even if they are not affiliated with CCMR (though check if the particular resource you want to use is available to you). A full list of their facilities is available at the website listed above.
CCMR has a small but neat and very useful machine shop in the basement of Bard Hall (C6). To use this, you need to see John Sinnott in B-57 Bard Hall, jps39@cornell.edu, 255-3371.
The sub-basement of Bard Hall (C6) and first floor of Snee Hall (C6) house a useful facility for microscopy -- optical, scanning electron and tunneling. If you want to see something `small' and are not sure whether you can do it or how you should do it, see John Hunt in SB56 Bard, hunt@ccmr.cornell.edu, 255-3789. There is an ion beam facility in Bard Hall and electron beam instruments in Snee Hall.
The CCMR computer facility is located in Clark Hall (D4).
