APPENDIX III: DESIR collaboration agreement After the construction of the DESIR infrastructure (RFQ cooler SHIRaC, high-resolution separator HRS, beams lines from S1, S2, and S3 to DESIR), the DESIR collaboration proposes the installation of a certain number of general equipment (stable ion sources, identification station, general-purpose ion buncher GPIB) which will be available to all experiments. This equipment will be provided by the collaboration as a whole or by different groups and financed by different means (ANR, regional grants etc.). Part of the equipment necessary to perform experiments in DESIR exists already or is presently built and commissioned. Other parts will be constructed in the next few years. This equipment is financed by different parts of the DESIR collaboration and will be installed permanently or for longer periods in the DESIR hall. Details of this process will be fixed in a Memorandum of Understanding which is presently being elaborated.

Neyens et al.), the University of Manchester (P. Campbell et al.) and the IPN Orsay (F. Le Blanc) with a total investment cost of 970 k€ a total absorption gamma spectrometer provided by CSIC Valencia (J.L. Tain et al.) with a total investment cost of 425 k€ the TETRA neutron multiplicity setup proposed by JINR Dubna (Y. Penionzhkevich et al.) with an investment cost of 200 k€ a neutron time-of-flight spectrometer provided by a CIEMAT (D. Cano Ott et al.) - LPC Caen (N.

Simpson (LPSC Grenoble) with an investment cost of 50 k€ a 4p charged particle array proposed by CEN Bordeaux-Gradignan (B. Blank et al.) and CSIC Madrid (M.J.G.
