We have arranged to borrow a set of gratings from Christian David to test the technique. We will look at suspensions of 10 micron poystyrene spheres undergoing colloidal crystallization in a 3mm capillary. equipment_required: experiment: Phase constrast imaging tests using gratings foreign_nationals: hazards: none instrument: 34ID-C coherent instrument_other: minimumdays: 4 name: Ian Robinson nonmembers: submit: Submit unacceptable_dates: outside the period june 20 to july 15 will be impossible due to travel from UK z34ID_change_undulator: no z34ID_details: THe gratings only work correctly at a particular energy. We don't yet know what energy the available gratings will need, but it is likely to be around 12keV. z34ID_parasitic: no #REMOTE_HOST: pool-71-249-17-160.nycmny.east.verizon.net #REMOTE_ADDR: 71.249.17.160 #CONTENT_LENGTH: 972 #HTTP_REFERER: http://www.uni.aps.anl.gov/admin/unireq.html #HTTP_USER_AGENT: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
