The Castaing Centrehas set up two committees :
- The Committee for Strategic Orientation (COS). It examines and decides on all questions concerning the general organisation and operation of the UMS. It is representative of the founding structures and meets twice a year ;
- The Operational Committee. This committee is consulted by the Director of the The Raimond Castaing Microanalysis Centre for issues of general orientation, budget, organisation, recruiting, training, conditions of work safety and security, ethical rules and the collective rules of discipline, the annual report, the preparation of the COS and any other issues worthy of attention.
