Optimize :Source and injection : proton only – like Cyclone 30 high current

Optimize proton acceleration 30-70 MeV - 750 µA

Ref: ECPM 09; Cyclone 30 intensity upgrade


Cyclone 70 proton only - sold to USA and Russia

Starting from Cyclone 70 XP installed in Arronax, France

Optimize : Magnet : isochronism for proton only

Optimize proton acceleration


Cyclone 70 proton only

Starting from Cyclone 70 XP installed in Arronax, France

Optimize : RF for proton only : 35-70 MeV , > 750 µA , Harmonic 4

• less turn, lower losses

Direct resonant RF coupling to amplifier (like Cyclone 30)

Optimize proton acceleration mode for high intensity


IBA DEVELOPMENT – PROTEUS ONE

Geets Jean-Michel

Development of a compact 235 MeV system for Proton therapy

Part II: IBA Customer Service and SCX users


What lies behind reliability?

How do we see the job?

How can you help us?

Current situation with SCX

What’s next?

IBA’s Customer Service


People

Skilled local staff can deal with/prevent many issues faster than IBA.

Tools

Having the right tool is the best way to do the job properly.

Parts

When problem is diagnosed, with well skilled staff, if part is missing,

there is no way to fix

What lies behind reliability? For any system


Engineers are able to fill the gap in knowledge/skills of the local staff

for normal PM

Engineers are able to fix higher level issues in EV with right tools/parts

Engineers are gathering and report issues in order to improve the

material we produce.

Engineers share their experience to increase the team’s knowledge.

How do we see IBA’s FSE


People

IBA has really few opportunities to train people on SCX machines

Last expert retiring, local staffs are knowing better

Tools

Many tools are common, not a real problem

Parts

Low volume

Quality not as good as we would like, since we rely on external

suppliers for designs we did not draw.

SCX situation?


IBA will reduce support of service agreements

Requests for help in a “best effort” mode

Provide help for a specific issue requiring special skills

Provide training within limits of available knowledge

IBA will provide spare parts in "best effort" mode

Parts that are usually ordered where stock or suppliers still exist.

Obsolete parts; try to provide a solution but no guarantee.

If a need for specific parts is existing, please express it clearly.

What’s next? Since 2014


RF field: CST

Magnetic field: OPERA Shielding+targetry: MCNP(X)/PHITS

Beam-line layout: PSI TRANSPORT

Injection/extraction: In-house tracking code

Mechanics: CATIA/ANSYS

Vacuum: In-house model+LTspice

R&D
