Perspectives for a high energy electron-cooling at LEAR: an experimental test

The feasibility of a high energy electron cooling device, has been studied through tests on a prototype of the electron device. The apparatus consists of a pulsed (20-6O KeV, 2 microsec) electron gun, a drift region 1 m long and a depressed collector to recover the electron energy. Tests on beam optics and energy recovery have been performed, a high efficiency for energy recovery has been obtained. The high energy device project is in progress

Experimental study of beam optics and energy recovery for a high energy electron-cooling device

The feasibility of a high-energy electron cooling device has been studied through tests on a prototype of the electron device. The apparatus consists of a pulsed ((20÷60) keV, 2 μs) electron gun, a drift region 1 m long and of a depressed collector for recovering the electron energy. Tests on beam optics and energy recovery have been performed, a high-energy recovery efficiency has been attained. Experimental results are discussed in this paper

High energy electron-cooling and related diagnostics

A project of high energy electron cooling for the LEAR facility at CERN, operating as a mini-collider between 0.6 and 2.0 GeV/c, is described. The electron beam should have the following characteristics: beam energy between 0.1 and 1 MeV, current 10A, momentum spread better than 10-3
