TERA CONTRIBUTIONS TO PARTNER

Ugo Amaldi University of Milano Bicocca and TERA Foundation

PARTNER – UA – 17.10.08

2

CNAO status

PARTNER – UA – 17.10.08

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

Medical Director: Roberto Orecchia Technical Director: Sandro Rossi PIMMS/TERA Hospital building

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

Cyclinac Programme

PARTNER – UA – 17.10.08

Cyclinac = Cyclotron + Linac for Image Guided HadronTherapy

PARTNER – UA – 17.10.08

chopped beam at 200-400 Hz modules

• f LIGHT

RF generation computer controlled source (synchro)cyclotron

Fast cycling beam for tumour multi-painting RF generators

11

Properties of the cyclinac beam

(*) With movable absorbers

The energy is changed by adjusting the RF pulses to the modules

1 second Yes No Synchrotron

• No

Yes Cyclotron Time needed for varying the energy Energy variation by electronic means Beam always present during treatments Accelerator 1 millisecond Yes Yes Cyclinac 50-100 ms (*)

Fast cycling

The cyclinac beam is ideal to paint many times moving tumours in 3D without variable absorbers

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

Other solutions based on solid detectors will be studied in parallel 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

What material? What thickness?

PROBLEMS: EFFICIENCY: Large coverage INSULATORS: Control the surface THIN SHEETS: Mounting technique PMQ 101
