  PERLE is a proposed high power Energy Recovery Linac, designed on multi-turn configuration, based on SRF technology, to be hosted at Orsay-France in a col-laborative effort between local laboratories: LAL and IPNO, together with an international collaboration involv-ing today: CERN, JLAB, STFC ASTeC Daresbury, Liverpool University and BINP Novosibirsk. PERLE will be a unique leading edge facility designed to push advances in accelerator technology, to provide intense and highly flexible test beams for component development. In its final configuration, PERLE provides a 500 MeV elec-tron beam using high current (20 mA) acceleration during three passes through 801.6 MHz cavities. This presenta-tion outlines the technological choices, the lattice design and the main component descriptions.

  Cooling of a high energy ion beam is essential for future electron-ion colliders to reach high luminosity. It is critical to demonstrate experimentally cooling by a bunched electron beam and to benchmark the experimental data with simulations. Such experimental and simulation studies were carried out by a collaboration of Jefferson Lab and Institute of Modern Physics (IMP), utilizing a DC cooler at IMP. The thermionic gun of the DC cooler was modified by pulsing its grid voltage to produce cooling electron pulses in a pulse length range of 0.07 - 3.5 µs, with a 250 kHZ repetition frequency. The performed experiments clearly demonstrated cooling of a RF focused ion bunches by this pulsed electron beam. The momentum spread of cooled ion bunch has been reduced from ~2x10-3 to ~6x10-4 in less than 0.5 second. The simulation results agree with the measurements qualitatively. In this paper, we present a brief overview of the experiments and also show the main experimental and simulation results.
