1) Thomas Jefferson National Accelerator Facility, CEBAF
6 GeV beam of up to 200uA polarized electrons,
3 experimental halls, continuous electron beam

i) Study in detail the nucleon's structure and nuclear structure
ii) Does the structure of the nucleon get modified inside the nucleus?
iii) Can we gain new insights into quantum chromodynamics by studying the propagation of charmed mesons in the nuclear medium? This needs a 12 GeV accelerator.
iv) Search for the exotic mesons predicted by the Standard Model of Particle Physics.

2) Relativistic Heavy Ion Collider (RHIC)
colliding beams of heavy ions with up to 100GeV per nucleon.
This machine will produce energy densities of nuclear matter that existed within the first few moments of time in the Big Bang. Nuclear densities may be sufficient to produce the quark-gluon plasma, a high energy state of matter in which quarks and gluons are no longer confined to single nucleons.

Nuclear densities will also be high enough to study the equation of state of nuclear matter in regions of interest to neutron star physics

3) Radioactive Ion Accelerator
This machine is being proposed as a means of producing and accelerating beams of radioactive nuclei which are of interest to nuclear astrophysics and nucleosynthesis. All the elements heavier than iron are produced in catastrophic stellar events called supernova explosions. The chain of element building in these explosions involves radioacive, unstable, nuclei.

4) Neutrino Observatories - Super Kamiokande, Sudbury Neutrino Observatory, SAGE and GALLEX, Amanda South Pole observatory, and others.

Neutrinos from the cosmos contain information about the stellar environments in which they were created and about particle physics properties.
