Electric field will be applied to the sample in-situ. equipment+required: Newport or Huber diffractometer is required.(Newport is prefered) Oxford Scintillation detector and CCD detector Displex cryostat. High voltage power supply. experiment: Diffuse scattering in Pb(Mg_1/3Nb_2/3)O_3 under applied electric field foreign+nationals: Danny Mannix (Citizenship: England) hazards: High voltage applied to the sample (0-300 V), although no open direct exposure to the high voltage is expected. All the high voltage connections will be inside of the grounded cryostat. Cryogenic temperatures will be used with the compressed He gas cryostat. name: Andrei Tkachuk nonmembers: Danny Mannix, Max Plank Institute, Germany station: 33ID-D unacceptable+dates: February 4-7 March 12-16 #QUERY_STRING: #REMOTE_HOST: bos.uni.aps.anl.gov #REMOTE_ADDR: 164.54.216.25 #CONTENT_LENGTH: 1146 #HTTP_REFERER: http://www.uni.aps.anl.gov/unireq.htm #HTTP_USER_AGENT: Mozilla/4.0 (compatible; MSIE 5.01; Windows 98)
