The HETE (High Energy Transient Explorer) is a small satellite observing and localising gamma-ray bursts in space. Once a burst is observed, information on its position will immediately be transmitted to researchers on the Earth. Thus the ground based observatories are able to study the burst right from the initial stage.

HETE was successfully launched on October 9 2000, andit has provided the scientific community with valuable information.

HETE is an international co-operation program, managed by the Massachusetts Institute of Technology (MIT, USA).
One of the participants is The Japanese Research Institute RIKEN which provided the satellite with the WXM (Wide field X-ray Monitor) instrument.

Oxford Instruments Analytical Oy manufactured four multi-wire, 1-dimensional proportional counters for this instrument under a contract with RIKEN. Each counter has three carbon fiber anode wires (10 micrometer diameter, hardly visible with the naked eye) and a large number of tungsten wires.
