The Scattering Experiments Chamber (SEC) 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. [1] SEC does not detect gamma radiation, and therefore is complementary to the ISOLDE Solenoidal Spectrometer (ISS) and Miniball experiments. [2]
The SEC experiment uses radioactive ion beams from ISOLDE, at the end of XT03 beamline of the HIE-ISOLDE facility. [3] The ion beam first passes through a collimator, of 15 mm aperture, surrounded by 4 silicon detectors, designed for beam optimisation. [4]
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 (DSSSD) which are positioned so that the angular coverage is optimised, depending on the experiment. [5] DSSSDs allow for efficient detection of all emitted particles in the reaction. [6] The main support for the detector is a circular movable table which has radially arranged holes at the centre. [4]
GLORIA (GLObal ReactIon Array) is a configuration used in SEC to measure fragments produced in reactions. It consists of six silicon telescopes, which surround a certain scattering angle of the reaction target (from 15° to 160°. [7] [8] GLORIA was designed to have a compact geometry with the ability to resolve mass and ion charge up to carbon isotopes, due to the two-stage DSSD telescopes. [8]
The SAND array is used at the scattering chamber SEC, for the detection of charged particles and neutrons. [9] The array consists of 30 modules, each being a plastic scintillator with fast photomultiplier tubes. The array can be moved to bring it closer to the target. [10]
