The Garcia Center operates as a "laboratory without walls." As in the past, graduate, undergraduate, and high school students will have unrestricted access to all listed facilities. Post-docs at each campus will continue to oversee operation of the more complex instruments. Mini-courses will be introduced to familiarize students with the principles as well as the practical aspects of key instrumentation. In addition, videoconferencing and internet technology will be employed to allow remote access to major instruments, beginning with the TOF-SIMS at Queens College. Outside grants will defray a substantial portion of the maintenance costs. The listed national facilities are directly accessible to the PIs through existing collaborations and agreements.
