Electron-cooling and SuperLEAR

In this report we present a short description of the project of an electron cooling device for the LEAR machine and the experimental results on a prototype of the electron device

Possibilities for high energy electron-cooling in LEAR

In this paper we present a short description of the project of an electron cooling device for LEAR operating as minicollider between 0.6 and 2 GeV/c for each beam, in order to improve the beam quaity and to increase the luminosity

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

The Fenice Detector At the E+e- Collider Adone

The FENICE detector, installed at the Frascati e+e- storage ring ADONE, for measuring the neutron e.m. form factors in the timelike region, is described. FENICE is a nonmagnetic detector and consists of a complex array of scintillators, limited streamer tubes and iron converters for detecting mainly the process e+e- --> nnBAR. Antineutrons are identified by the charged prongs produced in their annihilation and the antineutron velocity is measured by the retrieved annihilation time with respect to the beam crossing time. Neutrons are detected in plastic scintillator layers. To reduce the cosmic rays background a concrete shield, covered by an active veto system, is added
