Prototype ISR d'une chambre à fils multiples proportionelle (et métier à tisser)

A prototype chamber of the type to be installed in the aperture of the Split Field Magnet at the Intersecting Storage Rings. The chamber was light enough to be elegantly carried, thanks to the use of plastic foam sandwich construction (which had reduced the weight from 60 to 6 kg). This method of construction increased the useful volume by about 15 %.
