AbstractAbstract
[en] This paper is a review of the experimental situation of the antiproton-nucleus interaction studies at the LEAR facility of CERN. In particular the results obtained in the knowledge of the interaction of antiprotons with the nucleus by the experiment PS 184 (elastic and inelastic scattering) and PS 179 (devoted to the exclusive channels of the non-elastic reactions) are described.

AbstractAbstract
[en] Anti Ps can be continuously extracted from the EHF Stretcher by slowly displacing the proton beam towards an internal ribbon target. Due to the size of the ribbon target, the anti p emittances can be as small as a few mm.mrad, while the momentum bite is quite large (say 5%); the momentum resolution, on the other hand, can also be small, perhaps 0.1%, depending on the detailed design of the secondary beam optics. There are in principle four methods of cooling a particle beam: (1) radiation cooling; (2) electron cooling; (3) ionization cooling, and (4) stochastic cooling. The authors discuss there in turn. Beam storage is also outlined

AbstractAbstract
[en] On completion of the ACOL project, the increased beam intensity in the Antiproton Accumulator, AA, will be derived from extensions to the transverse and longitudinal acceptances via the new Antiproton Collector ring being constructed around the AA. Each of these extensions should give a factor of 3 to 4 improvement, i.e. an overall gain of at least 10 in anti-proton yield. The increased transverse acceptance has necessitated a redesign of the antiproton target station, which will be equipped to function with various passive and active targets. The antiproton collector lens will be a lithium lens, but high-current magnetic horns and a plasma lens are also under development. At start-up in 1987 antiproton yields into the ACOL nominal acceptance, Δp/p=6%, Ah, AV = 200 mm-mrad, are expected to be as predicted. Target and collector lens lifetime limitations may make further gains more difficult than initially supposed, but if these can be overcome another factor of two is possible

AbstractAbstract
[en] The technique of polarization of noble gas nuclei by spin exchange with optically pumped alkali vapor has achieved up to 30% polarization of 2 x 1019 atoms-cm-3 of 21Ne. 3He and /sup 129/Xe have also been polarized with respectively 5% and 80% polarization. Polarization of greater than 50% is likely to be achieved soon with 21Ne and similar results with 3He seem attainable. With this promise, the possibility is considered of using polarized nuclei as a filter for a specific antiproton helicity. Though 3He is a more likely candidate with one of three nucleons polarized, the extensive experience gained from and techniques developed for our 21Ne work can be extended. The anticipated properties and limitations of 21Ne and 3He targets are presented

AbstractAbstract
[en] A description is given of the recent performance of the LEAR storage ring. This includes the improvements made on the ultra-slow extraction (time structure, flux limitation), the progress on the semi-slow extraction (∼500 μs) at 61.2 MeV/c, and the results obtained from internal jet target operation at momenta higher than 800 MeV/c.

AbstractAbstract
[en] The CERN Antiproton Decelerator will deliver low energy beams to four experimental beam-lines installed within the accelerator circumference. The limited space available imposes tight constraints on the topology of the beam-lines needed by the experimental devices. In this paper, the general layout of the experimental area is reviewed. Furthermore, a discussion of the so-called measurement line for AD beam property measurements is included

AbstractAbstract
[en] An efficient beam collector and transport design is presented which transfers and matches a 4.5 Gev antiproton beam with momentum spread of /plus or minus/2% into the precooler admittance of 5.0/pi/ mm-mr. The limits of the transport are a solid angle acceptance of 5.0 msr and momentum pass band of /plus or minus/5%. A short focal length pulsed lithium lens serves as the collector. The following beam transport line is composed of: (1) vertical translation section; (2) horizontal translation section; (3) matcher; and (4) injector. Monte-Carlo techniques are utilized to evaluate effects of aberrations and multiple scattering upon the computed particle yields. Estimates are presented of the pion and muon fluxes injected into the precooler. 9 refs
