  We re­port the first las­ing of the ALICE IR-FEL, an os­cil­la­tor FEL at the UK’s STFC Dares­bury Lab­o­ra­tory. The ALICE (Ac­cel­er­a­tors and Lasers In Com­bined Ex­per­i­ments) fa­cil­ity is a test­bed for ad­vanced ac­cel­er­a­tor tech­nolo­gies and ex­per­i­ments, based on an En­ergy Re­cov­ery Linac (ERL) ac­cel­er­a­tor. First las­ing of the ALICE IR-FEL was achieved on Oc­to­ber 23rd 2010, mak­ing it the first FEL to op­er­ate in the UK, and the first FEL based on an ERL ac­cel­er­a­tor in Eu­rope. First las­ing was achieved at 27.5 MeV elec­tron beam en­ergy and 8 μm ra­di­a­tion wave­length. This re­port de­scribes the steps taken in com­mis­sion­ing the FEL, and the char­ac­ter­i­sa­tion of the FEL per­for­mance and out­put. Con­tin­u­ous wave­length tun­ing be­tween 5.7-8 μm (through vary­ing the un­du­la­tor gap) has been demon­strated.

  This paper con­sid­ers de­sign op­tions for a ded­i­cated light source test fa­cil­ity at Dares­bury Lab­o­ra­tory in the United King­dom. The fa­cil­ity lay­out should be eas­ily con­fig­urable to en­able ex­plo­ration of many re­search themes in­clud­ing: ul­tra­short pulse gen­er­a­tion; seed­ing and har­monic gen­er­a­tion; di­rect laser/elec­tron beam in­ter­ac­tions; com­pact FELs; high bright­ness pho­toin­jec­tors. The strat­egy is to de­velop and demon­strate novel con­cepts and ex­per­tise rel­e­vant to fu­ture gen­er­a­tions of FEL-based light sources, sig­nif­i­cantly short­en­ing the R&D phase of any fu­ture light source in the UK.
