abstract
ULTRACAM is an ultra-fast, triple-beam CCD camera which has been designed to study one of the few remaining unexplored regions of observational parameter space - high temporal resolution. The camera will see first light in Spring 2002, at a total cost of GBP 300 k, and will be used on 2-m, 4-m and 8-m class telescopes to study astrophysics on the fastest timescales.
