1 TERA CONTRIBUTIONS TO PARTNER Ugo Amaldi University of Milano Bicocca and TERA Foundation 1

2 CNAO status 2

3 The CNAO Foundation builds with INFN in Pavia the Centre designed by TERA on the basis of PIMMS. Total investment: 100 M, 80% from Health Ministry Hospital building High-tech building PIMMS/TERA 25 m MedAustron will build in Wiener-Neustadt a centre based on the construction drawings and the specifications bought from CNAO A French-Italian consortium has obtained the same drawings for an ETOILE proposal Medical Director: Roberto Orecchia Technical Director: Sandro Rossi 3

4 CNAO status in October 2008 Hospital Building 4

5 The synchrotron in February 2008 Dipole Sources Injection line Quadrupoles RF cavity 5

6 The synchrotron area in October

7 The vertical beam in October

8 TERA programmes 1. Cyclinacs : UA 2. AQUA = Advanced Quality Assurance: Fabio Sauli 8

9 Cyclinac Programme 9

10 Cyclinac = Cyclotron + Linac for Image Guided HadronTherapy RF generators Fast cycling beam for tumour multi-painting RF generation computer controlled source (synchro)cyclotron modules of LIGHT chopped beam at Hz 10

11 Properties of the cyclinac beam Accelerator Beam always present during treatments Energy variation by electronic means Time needed for varying the energy Cyclotron Yes Synchrotron No Cyclinac Yes (*) With movable absorbers No Fast cycling Yes Yes ms (*) 1 second 1 millisecond The energy is changed by adjusting the RF pulses to the modules The cyclinac beam is ideal to paint many times moving tumours in 3D without variable absorbers 11

12 Prototype by the INFN-CERN-TERA Collaboration : Module tested at LNS, Catania 2003 NIM paper 73 MeV with 3.5 MW 3 GHz proton linac 1.3 m Project value 15.7 MV/m measured 27 MV/m Half cells 12 Bridge coupler 12

17 Design of two 12 GHz accelerating structures and possibly construction/tests together with the CLIC = Compact LInac Collider group A. SCL very similar to LIGHT for IDRA mm mm B. ACS studied by TERA (R. Zennaro and A. Citterio) 17

18 AQUA Programme 18

19 The detectors of AQUA (for CNAO and later A.D.A.M.) 19

20 IN-beam-PET system first implemented in GSI by W. Enghardt et al GSI- Darmstadt MC simulated measured On-line determination of the dose delivered First time in 110 years! W.E. Statements for ENVISION: Two problems. 1. Radioactivity wash-out 2. Background that could be partially cured by Time of Flight (TOF) - WP1 of ENVISION In-beam-PET detectors 20 20

21 Main alternative: Resistive Plate Chambers = RPCs Time resolution : 0.1 ns 2 chamber coincidence within less than 0.2 ns corresponds to fix the source of the two-photon coincidence within less than 10 cm Other solutions based on solid detectors will be studied in parallel 21

22 What material? What thickness? 101 PMQ P. Fonte PROBLEMS: EFFICIENCY: Large coverage INSULATORS: Control the surface THIN SHEETS: Mounting technique 22

23 Large angular coverage with cheap gas chambers Optimization of the mechanical design in the transverse and longitudinal directions 23
