Electron cooling project at INS

At the INS, a project of electron cooling has started at the beginning of this year (1984). Since 1978, we have studied accelerator technologies for the accumulation and stochastic cooling of ion beams by using a storage ring, TARN. After completion of these experiments at the end of this year, we intend to shut down the machine and to construct a newly extended ring, TARN II, by using the most components of the present TARN and by adding some new elements. The main purpose in the TARN II is the study of accelerator technologies concerning synchrotron acceleration, beam cooling, slow extraction and so on. (orig./HSI)
