SEC experiment
The Scattering Experiments Chamber experiment is a permanent experimental setup located in the ISOLDE facility at CERN. The station facilitates diversified reaction experiments, especially for studying low-lying resonances in light atomic nuclei via transfer reactions. SEC does not detect gamma radiation, and therefore is complementary to the ISOLDE Solenoidal Spectrometer and Miniball experiments.
Experimental setup
The SEC experiment uses radioactive ion beams from ISOLDE, at the end of XT03 beamline of the HIE-ISOLDE facility. The ion beam first passes through a collimator, of 15 mm aperture, surrounded by 4 silicon detectors, designed for beam optimisation.The SEC chamber has a diameter of 1 m and height of 50 cm, with the reaction target placed in the centre on a motorised target holder. The target holder has the space for four targets, and each target can be moved in place via remote control. The reaction target is surrounded by double-sided silicon strip detectors which are positioned so that the angular coverage is optimised, depending on the experiment. DSSSDs allow for efficient detection of all emitted particles in the reaction. The main support for the detector is a circular movable table which has radially arranged holes at the centre.
