  18. TRImP Key Issues and Experiments • TRImP will be auser facility • open to outside users (first users from France already in 2004!) • KVIwill concentrate first on • CP/ T violation – electroweak tests • *b- decay (20,21Na, 19Ne, 39Ca) • * electric dipole moments (Ra, d ) •  applications • * ALCATRAZ (rare Ca isotope detection)

  21. TRImP AGOR is Indispensable for TRImP at KVI • Precison experiments require time to develop: AGOR & KVI ideal ( compare ISOLDE @ CERN or AD @ CERN ) • Various upgrades and adaptations • New Beams • e.g. 208Pb • new sources (metals) • improved transmission • ….. • High Power ( 100W…1 kW) • new extraction • beam stops • beam monitoring • ….. •  S .

Searches for EDMs in charged particles: Novel Method invented Motional Electric Fields exploited • International Collaboration • (USA, Russia, Japan, Italy, • Germany, NL, …) • 3 possible sites discussed: • BNL, KVI, Frascati • Limit dD <10-27 …10-29 ecm • Can be >10 times more • sensitive than neutrondn R0 1..2 m

  25. TRImP Goals of TRImP @KVI • A facility is created for KVI scientists and outside users • (the first groups are already active, proposals P01,P02,P03,P04 ) • Study fundamental interactions using stored (radioactive) • isotopes General Time Lines • Project started 2001; setup facility until end 2005 • Exploitation of facility until 2013 (also in new FOM strategic plan from 2004) • TRImP became a managed program in July 2001 Facility Setup is more or less on Schedule
