Summary

The possibility of using electron cooling in the LEAR ring, operating as a p- p - collider between 0.6 and 2.0 GeV/c, is investigated. Cooling times at different energies and expected luminosities are evaluated. The project of an electron source ((100÷700) keV, 10A d.c.,j==5·103 A/m2) with high-efficiency energy recovery is proposed. Problems regarding cathode, optics, beam qualities and diagnostic methods are tackled.

Электронное охлаждение при высоких знергиях в кольце LEAR

Реэюме

Исследуется воэможность испольэования злектронного охлаждения в кольце LЕАR, работаюшем в режиме p- p - соударений с импульсами от 0.6 до 2.0 ГзB/c. Оцениваются времена охлаждения при раэличных знергиях и ожидаемые светимости. Предлагается проект злектронного источника ((100÷700) кзB, 10 A,j=5·103 A/m2) с высокой зффективностью регенерации знергии. Рассматриваются проблемы, касаюшиеся катода, оптики, качества пучка, и методов диагностики.

Riassunto

Si valuta la possibilità di usare il raffreddamento ad elettroni nell’anello di accumulazione LEAR, operante come « p- p - collider » tra 0.6 e 2.0 GeV/c. Sono valutati i tempi di raffreddamento a differenti energie e le luminosità previste. Si propone il progetto di una sorgente di elettroni ((100÷700) keV, 10 A d.c.,j=5·103 A/m2) con recupero di energia ad alta efficienza. Si affrontano i problemi riguardanti il catodo, l’ottica, la qualità del fascio e i metodi diagnostici.
