MUST2 MUr de STrips - Wall of STrips

                 MUST2                      

The MUST2 detector was conceived to carry out research programs on the evolution of shell structure as a function of the isospin degree of freedom by doing direct nuclear reactions induced by radioactive beams. Experiments have been done at the GANIL (the Large National Heavy Ion Accelerator at Caen, Grand Accélérateur National d’Ions Lourds) facility, using SPIRAL beams in the SPEG or in the VAMOS areas, or fragmented beams produced in the LISE areas. Recenlty experiments were also carried out at RIKEN using the beams of the RIBF machine or the fragmented beams delivered in the RIPS area.  

 The MUST2 was specifically designed to optimize the exploitation of the exotic beams and the quality of the observable measurements.  

In the years 2003-2006, the nuclear structure and reaction groups of CEA-Saclay, IRFU/SPhN,  CNRS IN2P3 IPNO and of GANIL have developed and built the device  with the technical divisions of these institutes :  the IRFU SEDI  (for the ASIC Mate : Must2 Asic Time and Energy), the GANIL acquisition-electronics group, and the IPNO detector division for the  telescope detectors and the mechanics.
 MUST2 represents the state of the art in the field of the telescope arrays.

Since 2010, this system is composed by a set of 8 telescopes for the measurement of energy, positions and time of flight of the light charged particles; each module consists of 3 detection stages: a 300µm-thick double-sided Silicium strip (DSSD) with an active area of 10 by 10 cm2, backed up by a second stage of 3mm-thick Silicium-Lithium and a 3 cm-thick CsI.
