Facilities

 

Building-Photo-300x134CNDE is housed at the Applied Sciences Complex Buildings II and III with an area of ~52,000 square feet. Over 25 full time staff support the research efforts of
CNDE with additional support provided from faculty and scientific staff in the College of Engineering and the Ames Laboratory. Typically 50 to 100 students are involved in research and education activities at CNDE including approximately 30 students enrolled in the NDE Minor program.

CNDE includes experimental resources in excess of $5M with brief details provided below for each of the major methods:
