Kinetics and structures will be studied in real time. The target systems are Ag/Si(111), Pb/Si(111), etc. Beam time allocation in time shared mode is quite desirable when the other experiment operates at a 20 - 30 KeV photon energy. Two short time slots with a 2 day break in between is most desired for substarte change. Also, allocation of multiple 8-16 hr slots scattered far apart is acceptable for this kind growth experiment. equipment+required: surface diffractometer, Roper Scientific CCD, MCA experiment: Growth of metal nanocrystals at low temperature foreign+nationals: hazards: cryogenic name: Hawoong Hong new+request: on nonmembers: station: 33ID-E unacceptable+dates: #QUERY_STRING: #REMOTE_HOST: hong2.uni.aps.anl.gov #REMOTE_ADDR: 164.54.216.28 #CONTENT_LENGTH: 853 #HTTP_REFERER: http://www.uni.aps.anl.gov/unireq.htm #HTTP_USER_AGENT: Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)
