TRImP
Goals of TRImP

• Study fundamental interactions using
  radioactive isotopes
• in traps

• A facility will be created for in house and
  outside users

General Time Lines

• Project started 2001 setup facility in 4 years
  

• TRImP became a managed program in July 2001

• Exploitation of facility until 2013

• TRImP will evolve into a 50 user of AGOR

• Midterm review in 2008

Some Questions related to TRImP Physics

• Origin of Parity Violation in Weak Interactions

• ? details of b-decays
• Na, Ne isotopes

• (nature prefers lefthandedness)

• Dominance of Matter over Antimatter in
  Universe ?

• CP - Violation, Time Reversal Symmetry,
  Parity Violation

• ? permanent electric dipole moments ?
• Ra isotopes

Some Weak Interaction Experiments
Experiments on b-Decays in Traps
b-n correlations 6He,14O, 19Ne, 35Ar, 38mK
GANIL,ANL,LBNL, ISOLDE,TRIUMF, KVI b-
asymmetry 19Ne, 20Na, 21Na, 37K,
82Rb LBNL,TRIUMF, LANL, KVI inclusive
6He, 32Ar ISOLDE/Seattle, Leuven, measurements
GANIL
a lot of activity ? concentrate on your strength
Experiments on Parity Violation in Traps
Atomic parity 210Fr, 211Fr Stony Brook, JILA,
violation INFN

TRImP

• Precision Experiments different in type from
• most previous Nuclear Physics Experiments

• ? Most difficult part starts after isotopes are
  
• produced and trapped

• Advantages of KVI

• ? Sufficient beam made available for
• optimizing experiments

? Unique combination of facilities and
experienced people
