The Advanced X-ray Astrophysics Facility will be an X-ray observatory built around a large-area, high-resolution grazing incidence X-ray telescope. Designed to operate in space for at least 15 years, AXAF will be operated as a major national facility with the majority of the observing time set aside for guest investigators. The instruments that will detect the X-rays will be supplied to the observatory by the scientific community. A discussion of the categories of instrumentation and the interface requirements that they will most likely impose is presented.
