of the basic physics program (i.e. more operating funds) and a systematic program of funding other important physics facilities (additional construction funds). It is this multi-faceted approach which is needed to restore the strength and vitality of US physics, thus building a solid foundation upon which can rest a superstructure of US economic well being and military strength.

TABLE I. MAJOR NEW FACILITIES

HIGH ENERGY PHYSICS

SUPERCONDUCTING SUPER COLLIDER

The SSC would supply colliding proton beams at 40 TeV, the highest energies proposed to date. It would allow the search for heavier particles, to answer the question of what generates mass and to test new theoretical ideas about the fundamental nature of matter.

NUCLEAR PHYSICS

TOTAL COSTS

$3.2B

CONTINUOUS ELECTRON BEAM ACCELERATOR

FACILITY (CEBAF)

$225.OM

CEBAF is a 4-GeV linear-accelerator stretcher-ring complex to investigate the microscopic quark-gluon aspects of nuclear matter.

RELATIVISTIC HEAVY ION COLLIDER (RHIC)

$325.OM

RHIC is a mahine that would accelerate heavy ions to 10's of GeV per nucleon. The purpose of RHIC is to investigate the possibilities of quark-gluon plasma high density nuclear matter.

CONDENSED MATTER PHYSICS

1-2 GeV SYNCHROTRON

$98.OM

This Synchrotron is designed for insertion devices to produce high brightness sources of radiation in the ultraviolet and soft X-ray region of the spectrum to explore the electronic structure of matter.

6-7 GeV SYNCHROTRON

$385.OM

This Synchrotron is optimized to create extremely high brightness sources of Xray radiation for exploration of the structure of surfaces, interface biological molecules and other materials.

HIGH FLUX REACTOR

A new high flux reactor would increase the neutron flux for various materials science experiments by over an order of magnitude. Neutron scattering is essential for understanding excitations of matter in regions not accessible by other techniques.

$300.OM

PLASMA PHYSICS

COMPACT IGNITION TOKAMAK (CIT)

$357.OM

The next step in magnetic fusion is exploring the behavior of a fusion ignited confined plasma. The CIT would allow studies of the behavior of such plasmas and would act as an intermediate step to a fusion reactor.

Fig. 1 Projected funding needs for four subfields of physics in the Department of Energy, in current dollars. (a) High Energy Physics, (b) Nuclear Physics, (c) Condensed Matter Physics, and (d) Plasma Physics. No increases in the operations budgets have been included other than 3% inflation per year.

Fig. 2 A compilation of physics opportunities and needs. The growth in "small physics" is taken to be a doubling in 5 years. The facilities are those shown in Fig. 1.

Fig. 3 The same as Fig. 2, but with projected inflation averaging 6% per year for construction and 3% for operations.
