master detectors:

The neutrons are usually detected in coincidence with the emitting sources. The detection of these heavy nuclei or fragments is taken into account by specific master detectors: Silicon telescopes, parallel plate avalanche counters, channel plates,...

Experiment E236 at GANIL (1994): two 5x5 cm² Silicon telescopes
are used at forward angles to detect the projectile-like fragment
and two 16x16 cm² parallel plate avalanche counters XYZA
at backward angles to detect the target-like fragment.



 Experiment "bimodal fission" at VIVITRON (1996): two small channel
plates (CORSET) deliver the start signal and four bigger ones record
the stop and the position signals of the fission fragments.
