Some Questions related to TRImP Physics
• Origin of Parity Violation in Weak Interactions
• (nature prefers lefthandedness)
 details of b-decays
Na, Ne, Ca isotopes
• Dominance of Matter over Antimatter in Universe ?
CP - Violation, Time Reversal Symmetry, Parity Violation
 permanent Electric Dipole Moments ?

• R and D test both Time Reversal Violation
• D  most potential
• R  scalar and tensor (EDM, a)
• technique D measurements yield a, A, b, B

EDMs violate
- Parity
- Time Reversal
-CP Symmetry
Advantage over “best“ atom so far (199Hg)
- close states of opposite parity
 several 10 000 enhancement possible
- some nuclei strongly deformed
 may give nuclear enhancement

Key Issues and Experiments
will be a user facility
 open to outside users (first users from France already in 2004!)
will 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)

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
• …..

Goals of TRImP @KVI
• Study fundamental interactions using stored (radioactive)
isotopes
• A facility is created for KVI scientists and outside users
(the first groups are already active, proposals P01,P02,P03,P04 )
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
• Opportunities for low energy
Fundamental Symmetries and Interaction research
• TRImP Facility ready for first users
