15. Collaboration at Gran Sasso undermountain laboratories: - Borexino - Opera

16. BOREXINO: detector 18m 13.7m Main Goal:Main Goal: sub-MeV neutrinos detection (solar-Be7) Target mass = 300/100tons organic scintillator PC + PPO (1.5g/l) Detection by ES  careful background subtraction + high level of radiopurity required

17. BOREXINO: subsystems Scintillator purification systems:  Water extraction  Vacuum distillation  Silicagel adsorption CTF + DI Water plant Storage tanks: 300tons of PC detector

18. Dubna team (LPP) did the following: Dubna group of JINR has performed the following jobs in the frame of identifying common tasks and collaborating teams from both sides. - testing of VME electronics for the experiment, - tuning flash electronics and analysis - participated in the PMT finishing, the mounting and cleaning - participation in production of the analog electronic modules for the experiment - proposed suggestion for upgrading Borexino prototype to be able to study solar pp-neutrino. - calibration big size of PMT in monitor and muon system (more than 2700PMT) - complete DAQ production and test of the program complex - Dubna physicists suggested and made the analysis of the data of CTF-detector, which gives a new physical results

19. Future plan Expected fill operations in 2006 that will bring the Borexino detector to the data taking stage : Data taking with water -3-4 monthes Start filling scintillanting liquid and than Start data taking

20. Collaboration "Ion sources for accelerator injection" of INFN-LNS (Catania) – IPPLM (Warsaw) – IP (Praha) – JINR (Dubna). The Collaboration was based on the coupling of a LIS and an ECR ion source.
