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.

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

Measurement of the proton form factor in the time-like region

An experiment (LEAR: PS170) has been designed to detect the annihilation of antiprotons in electron-positron pairs. It aims to measure the proton form factor in the time-ike region and to observe the spectrum of vector mesons between 1 and 1.6 GeV

Status and future of the experiment PS170

The LEAR experiment PS170 is designed to detect the e+e- pairs from pbar annihilation. Data have been taken at 300, 600 and 1500 MeV/c incident momenta. The analysis of the 300 MeV/c data gave 200 2-body events clearly separated from the hadronic background
