FEEDBACK FROM BEAM FEEDBACK FROM BEAM DEVELOPMENT DEVELOPMENT A. Galat , Sources and Injectors Service Head A. Galat , Sources and Injectors Service Head LNL User Community Annual Meeting, LNL User Community Annual Meeting, Legnaro Legnaro 05/11/2019 05/11/2019
BEAM REQUESTS BEAM REQUESTS Cd Cd 204Hg 204Hg Serious risks for health 152Gd 152Gd Set up specific procedures 186W 186W 14C 14C Radiation Protection issues 238U 238U No particular problems 162Dy 162Dy 11B 11B QUESTIONS How wide is the convergence on a given proposal? Is there an expiring date of the proposals? (developed beams never requested) Legnaro, 05/11/2019 Alessio Galat LNL User Community Annual Meeting
BEAM REQUESTS BEAM REQUESTS BEAM PRODUCTION IN EUROPE BEAM PRODUCTION IN EUROPE Cd, U and B already produced No information about Hg, Gd, W, Dy Legnaro, 05/11/2019 Alessio Galat LNL User Community Annual Meeting
BEAM REQUESTS BEAM REQUESTS FEEDBACK FROM ENVIRONMENTAL MANAGEMENT SYSTEM FEEDBACK FROM ENVIRONMENTAL MANAGEMENT SYSTEM Cd and Hg Authorization for the use of carcinogenic substances Specific health surveillance Definition of procedures for source preparation Definition of procedure for vacuum system maintenance Definition of procedure for maintenance operations Cadmium is produced at GANIL with the ECR from oxide (oven), but for the rules we must follow this doesn t change the situation. Waiting from information from the colleagues of the Ion Sources Group Legnaro, 05/11/2019 Alessio Galat LNL User Community Annual Meeting
BEAM REQUESTS BEAM REQUESTS FEEDBACK FROM ENVIRONMENTAL MANAGEMENT SYSTEM FEEDBACK FROM ENVIRONMENTAL MANAGEMENT SYSTEM 152Gd and 186W Definition of procedures for source preparation Definition of procedure for vacuum system maintenance Definition of procedure for maintenance operations POSSIBLE PRODUCTION TECHNIQUES ECR (sputtering) Difficult to produce Usually low efficiency Needs enriched isotopes Performances not predictable TANDEM: Difficult to produce Performances not predictable Gd needs hydrogen (specific authorization) Very high consumption of the strippers Legnaro, 05/11/2019 Alessio Galat LNL User Community Annual Meeting
BEAM REQUESTS BEAM REQUESTS FEEDBACK FROM RADIATION PROTECTION FEEDBACK FROM RADIATION PROTECTION 238U with PIAVE-ALPI Visit at GANIL in 2018 with L. Sarchiapone to know specific issue for source preparation and maintenance ECR by sputtering (metal rod) Expected 0.5-1 pnA at the experiment Energies: 6.9 MeV/A, 7.5 MeV/A (CR21), 7.8 MeV/A (CR21-22) Needs a specific authorization U-U reaction on the FCs or loss points at high energy: neutron production Could be also produced with the ADIGE Injector (same issues at high energy) 14C with Tandem Carbon can be easily produced with negative sources The activity itself is not a problem Implantation could cause problems FOR THOSE SPECIAL BEAMS THE DISCUSSION GOES BEYOND THE SIMPLE FEASIBILITY WITH ION SOURCES Legnaro, 05/11/2019 Alessio Galat LNL User Community Annual Meeting
CONCLUSIONS CONCLUSIONS Cd and Hg should be avoided For U, besides the authorization, it is necessary to test Ta first B is already available, as well as not radioactive C (14C needs a dedicated discussion) It is reasonable to plan 1-2 developments/y for each ion source (without considering the time to set up specific procedures and/or authorizations): Dy (oven) and Ta (sputtering) with ECR Gd and W with Tandem? (depends on the specific experiment) A FINAL LIST OF PRIORITIES FOR BEAM DEVELOPMENTS SHOULD BE PRODUCED AFTER AN INTERACTION BETWEEN DIFFERENT ACTORS (ION SOURCES AND ACCELERATORS OPERATIONS, RSPP, RADATION PROTECTION SERVICE, USERS), ESPECIALLY IN THE CASE OF 14C AND 238U Legnaro, 05/11/2019 Alessio Galat LNL User Community Annual Meeting
