Geant 4 Collaboration 5 Geant 4 Collaboration 5

Purpose of the Project • To collaborate on beam simulations based on Geant 4 Purpose of the Project • To collaborate on beam simulations based on Geant 4 – Beam here = secondary particles produced by collision on a fixed target. – Eg: isotope production by proton beam on carbide uranium target • Initial motivation is for the Korean “Rare Isotope Science Project” (RISP) project, at the “Institute for Basic Science” (IBS) in Daejeon. – Interest in Nuclear physics, Nuclear data for fast neutrons, Material science, Nuclear astrophysics, Atomic & particle physics, Medical and biological science. – Proton, oxygen, xenon & uranium beams of a few 100 Me. V/u – Under construction • Goals: – Assess Geant 4 performances in predicting isotope production. Present activity – Use it to anticipate isotope natures and production yields. – Foresee what measurements apparatus would be appropriate • Note that the study interest is not limited to RISP.

Group activities • The Korean and French teams have indeed developed Geant 4 R&D Group activities • The Korean and French teams have indeed developed Geant 4 R&D working within Geant 4 collaborations. => Contributions on Geant 4. 10. 1 release (Dec. 5, 2014) • KISTI team has been working on Geant 4 Quality and Assurance and also Geant 4 beam simulations for secondary beam. • The French team has been working on beam simulations for particle physics accelerators (ATF 2) and is now involved in medical applications. It is also developing the “event biasing” techniques in Geant 4.

Beam Simulations (1/2) • Goal 1. To find optimized physics list compared to reference Beam Simulations (1/2) • Goal 1. To find optimized physics list compared to reference data 2. Using the optimized physics, to do beam simulation 3. To study the physics properties of secondary beam (mass, momentum, etc. ) for experiments • Beam and target – Beam: p, … – Target: 238 U, UC, … Þ French Group supports physics list and event bias. - INCL++ has recently been extended to higher energies up to 15 -20 Ge. V. 13

French Group Activity French Group Activity

French group activity (1/2) • French group involved in development for medical beam instrumentation. French group activity (1/2) • French group involved in development for medical beam instrumentation. – In the context of the French “GDR MI 2 B” – Development and delivery of beam profilers (hodoscopes made of plastic fibers + camera) used in CNAO (Pavie, Italy) and Med. Austron (Wiener Neustadt, Austria). Now done. CCD camera Hodoscope developed by M. Haguenauer & Co. , now retired. Fiber plane (other direction plane on the other side) • Started feasibility study of beam profiler using secondary electron emission – Motivated by IBA company needs

French group activity (2/2) • Development of “event biasing” techniques in Geant 4 – French group activity (2/2) • Development of “event biasing” techniques in Geant 4 – Revision and uniformity of the set of existing techniques – Extension to other techniques: • • Popular in other simulation packages, but not present in Geant 4 up to now Biasing of physics process interaction laws Biasing in final state production Both. – Development released in last Geant 4 version 10. 1 – Still continuing now. • Expecting to provide biasing functionalities at the level of other existing simulation packages – With the advantage of Object Oriented technologies: the user can extend the functionalities, not only use them.

Plan • On the scientific side – To continue with beam simulation – To Plan • On the scientific side – To continue with beam simulation – To study target optimization • On the off-line meeting – 2015 Geant 4 Collaboration meeting • • Sep. 28 ~ Oct. 2, 2015 @ Fermilab, USA Products and face to face meetings => To achieve common goals
