Description
The standard model of particle physics has proved to provide a good
description of almost all known particle physics processes. Despite it's suc-
cesses, however, the standard model is known to be incomplete, eg. in that
the standard model parameters are arbitrary and derived from experiment
rather than a priori.
Experiments to test for physics beyond the standard model are being
developed to probe the ultra-high energy regime, which probes directly the
new physics processes. A second class of experiments searches for the ef-
fects of new physics at lower energies by performing precise measurement of
observables which are calculable from the standard model and attributing
any variation to new physics. Recent years have seen a plethora of such ex-
perimental proposals which make use of existing accelerator facilities (e.g.,
the JLab Qweak and PREx proposals) as well as experiments which borrow
techniques from Atomic, Molecular, and Optical (AMO) physics. Among
the latter we may note Atomic Parity Violation (APV) experiments, neu-
trinoless double beta-decay searched, as well as measurements of correlation
coeffcients in the decay of radioactive atoms.
In this talk I will discuss the plans of performing such high precision
searches at the WI, using a high-flux d+t neutron generator to produce
6He and 8Li by (alpha, n) reactions. This in turn will lead to experiments at
the upcoming 40 MeV, 2 mA, proton and deuteron SARAF accelerator in
Israel. The SARAF accelerator will provide record yields of light radioactive
beams (such as 8Li and 6He), of O(1012) atoms/sec. The talk will address
the present R&D efforts toward this goal and discuss possible collaborations
with ongoing RNB trapping programs. Of particular emphasis is the use for
such measurements of an electrostatic trap, that offers numerous advantages
over other possibilities.
