Computer facilities

The XRF laboratories have several desktop and notebook computers, a flat-bed scanner and a color printer.

There are several microcomputers with software capable of controlling the K XRF measurement systems, transferring the data from the Multi-Channel Analyzer of the K XRF systems and performing analyses of the spectra collected. 

Data are stored and secured on the XRF group's primary domain controllers in a RAID (5) with daily digital backup. Access to both general and data areas of the server is restricted by passwords and administration rights. There is no guest access. The domain is administered by Dr. Todd. The XRF web site is hosted on Mount Sinai servers.

Statistical analysis is performed with programs written in-house and with licensed versions of statistical analysis programs (for which Mount Sinai levies an annual fee).

Communications facilities for interaction with other researchers are available via LAN.
