PHIL: A TEST BEAMLINE AT LAL Specifications of PHIL R. Roux, M. Bernard, G. Bienvenu, S. Cavalier, M. Joré, B. Leblond, B. Mercier, B. Mouton, C. Prevost, A. Variola LAL, bâtiment 200, Université Paris-Sud, 91898 Orsay, France SERA PHIN GOAL: construction of a small accelerator at LAL, E < 10 MeV, Q < 3 nC, single bunch, frep = 10 Hz MOTIVATION: test accelerating structures, especially RF guns applications such as interaction with a laser, calibration of diagnostics etc training for young scientists Specifications of PHIL BEAMLINE Phase 0 Phase 1 Energy (MeV) 6 10 Charge (nC) 0.1 3 rms bunch length (ps) 4 rms energy spread (%) 0.3 < 2 % Normalized rms emittance (pmmmrad)  1 < 20 Phase 1 (after 2009): photo-cathode preparation chamber, booster diagnostics (Cerenkov, screens and CCD camera, emittance) =>delayed because of a lack of funds spent in supplementary radiation shielding Main Components RF gun Laser PHIN* gun: European contract to provide one gun for the CTF3 drive beam linac => brazing failure a twin for PHIL => sent to CERN Bought to HighQ company Provisory solution: ALPHAX RF gun 2 issues built by LAL for the Strathclyde University (UK) (nm) 262 W (µJ) 90 Dt (ps) 10 Frep (Hz) 5 (100) 2.6 cells at 3 GHz symmetric coupling (b = 1) with a co-axial “doorknob” antenna elliptic irises 2.6 cells at 3 GHz symmetric coupling (b = 3) elliptic irises NEG pumping through the gun walls Diagnostics Magnets 2 WCM with 4 electrodes: beam positions (X, Y) and charge 2 Faraday cup in the 2 ways after the dipole: charge  One couple of coils around the gun, Bz max = 0.33 T and one coil in the middle of the beamline Bz max = 0.5 T  2 H&V steerers  A dipole retrieved from the old injector of TTF (60°, r = 0.7 m) for energy measurement Beam dynamic simulation Code: PARMELA modified by B. Mouton E  6 MeV e = 4 pµmrad sz = 2.6 ps Parameters: Q = 0.1 nC Laser, sr = 1.4 mm, 10 ps PHIN gun, 85 MV/m 5000 macro-particles Status of the Project RF gun and RF network installed Laser and Control room ready Low level RF ready Modulator-Klystron to be tested cabling in progress vacuum chambers laser transport line End of installation, July 2008 Authorization of Radiation Safety Authorities End of June 2008 Commissioning in Fall 2009 * We acknowledge the support of the European Community-Research Infrastructure Activity under the FP6 “Structuring the European Research Area” programme (CARE, contract number RII3-CT-2003-506395).
