Diffraction dissociation in 205 GeV/c $pi$$sup -$p two- and four-prong interactions
From meeting of the division of particles and fields; Berkeley, California, USA (13 Aug 1973). Data are presented on diffraction dissociation in pi /sup -/p yields pi /sup -/p and pi /sup -/p yields pi /sup -/ pi /sup - / pi /sup +/p interactions at 205 GeV/c. Mass spectra and cross sections for pion dissociation and nuclear dissociation are presented. (LBS)

Effect of component performance perturbations on the efficiency of injection of neutral beams into thermonuclear reactors
From 5th symposium on engineering problems of fusion research; Princeton, New Jersey, USA (6 Nov 1973). The effect of component performance perturbations on the efficiency of injection of neutral beams into thermonuclear reactors is discussed for a specific type of a neutral beam injector. Based on the model chosen, which includes using direct conversion of the unneutralized portions of the ion beam and recovery of the losses from each element of the injector system, quantitative effects of component performance perturbations are presented as a function of the injected deuterium atom energy, using positive and negative deuterium ions. The component performances having the largest leverage on the system efficiency are, in decreasing order, the accelerator efficiency, the trapping fraction, the neutralizer loss direct conversion, and the neutralizer power efficiency.

Secondary containment system for a high tritium research cryostat
A 4.2- to 300-K liquid helium cryostat was constructed for cryogenic samples of D-T containing up to 4 x 10$sup 14$ dis/s (10,000 Ci) of tritium radioactivity. The cryostat is enclosed in a secondary box, which acts as the ultimate container in case of a tritium release. Dry argon is flushed through the box, and the box atmosphere is monitored for tritium, oxygen, and water vapor. A rupture disk and abort tank protect the box atmosphere in case the sample cell breaks. If tritium breaks into the box, a powdered uranium getter trap reduces the 4 x 10$sup 14$ dis/s (10,000 Ci) to 4 x 10$sup 9$ dis/s (0.1 Ci) in 24 h. A backup palladium-zeolite getter system goes into operation if an overabundance of oxygen contaminates the uranium getter. (auth)

Determination of the pr of laser fusion targets using the. cap alpha. -particle TOF technique
A computer code was written to describe the alpha particle energy loss. The problem of a symmetric compression of the DT gas by an exploding microsphere is analyzed. The code calculates the energy spectrum of a Gaussian distribution of alpha particles after passing through the compressed gas and the exploded glass. The calculations are being used to determine design parameters for diagnostic instruments for measuring charged particle energy distributions from laser fusion targets. (MOW)

Effects of fill pressure and pulse simultaneity on the laser driven implosion of dt filled glass microshells
This paper discusses a series of experiments performed with the LLL two-beam laser system, JANUS. The JANUS laser is capable of focusing approximately 500 Gigawatts of 1.06 ..mu.. power (40 J in 80 psec) on laser fusion type targets. In these experiments, the targets were deuterium tritium (DT) filled glass microshells with aspect ratios of 100 to 200. Targets of this type operate in what is commonly called the exploding pusher mode. The result is that the glass shell surrounding the DT gas (the thermonuclear fuel) effectively explodes, and consequently from geometry, also implodes and compresses and heats the DT gas to TN conditions. The advantages and disadvantages of the exploding pushers type target, as compared with the high density isentropic implosion target of the future, is illustrated.

Interaction of 1.06$mu$m laser light with spherical targets imbedded in low density foam
Computer calculations of the interaction of a 1.06 $mu$m laser pulse with a spherical DT-filled glass shell embedded in low density foam are compared with experimental results. Poor coupling of the absorbed energy to the spherical capsule was observed, resulting in a barely detectable neutron signal. The x-ray micrograph shows that the electron conduction in the target was strongly inhibited. Calculational results are presented that indicate the inhibited electron conduction may be the result of large spontaneously-generated magnetic fields. Calculations including the magnetic field are seen to agree reasonably well with the experiment. (auth)

Low power multiple shell fusion targets for use with electron and ion beams
Use of double shell targets with a separate low Z, low density ablator at large radius for the outer shell, reduces the focusing and power requirements while maintaining reasonable aspect ratios. A high Z, high density pusher shell is placed at a much smaller radius in order to obtain an aspect ratio small enough to protect against fluid instability. Velocity multiplication between these shells further lowers the power requirements. Careful tuning of the power profile and intershell density results in a low entropy implosion which allows breakeven at low powers. Ion beams appear to be a promising power source and breakeven at 10-20 Terrawatts with 10 MeV alpha particles appears feasible. Predicted performance of targets with various energy sources is shown and comparison is made with single shell targets. (auth)
