  Alba is a third gen­er­a­tion syn­chrotron lo­cat­ed near Barcelona in Spain. The final com­mis­sion­ing of all ac­cel­er­a­tors and beam­lines start­ed the 8th of March 2011. The Alba con­trol sys­tem is based on the mid­dle layer and tools pro­vid­ed by TANGO. It ex­ten­sive­ly uses the Sar­dana Frame­work, in­clud­ing the Tau­rus graph­i­cal toolk­it, based on Python and Qt. The con­trol sys­tem of Alba is high­ly dis­tribut­ed. The de­sign choic­es made five years ago, have been val­i­dat­ed dur­ing the com­mis­sion­ing. Alba uses ex­ten­sive­ly Eth­er­net as a Field­bus, and com­bines disk­less ma­chines run­ning Tango on Linux and Win­dows, with spe­cif­ic hard­ware based in FPGA and fiber op­tics for fast real time trans­mis­sions and syn­chro­niza­tions. B&R PLCs, ro­bust, re­li­able and cost-ef­fec­tive are wide­ly used in the dif­fer­ent com­po­nents of the ma­chine pro­tec­tion sys­tem. In order to match the re­quire­ments in terms of speed, these PLCs are some­times com­bined with the MRF Tim­ing for the fast in­ter­locks. This paper de­scribes the de­sign, re­quire­ments, chal­lenges and the lessons learnt in the in­stal­la­tion and com­mis­sion­ing of the con­trol sys­tem.

  High ac­cu­ra­cy low cur­rent read­out is an ex­ten­sive­ly de­mand­ed tech­nique in 3rd gen­er­a­tion syn­chrotrons. Whether read­ing from scin­til­la­tion ex­cit­ed large-area pho­to­di­odes for beam po­si­tion mea­sure­ment or out of gold mesh­es or metal­lic coat­ed sur­faces in drain-cur­rent based in­ten­si­ty mon­i­tors, low cur­rent mea­sure­ment de­vices are an ubiq­ui­tous need both for di­ag­nos­tics and data ac­qui­si­tion in today's pho­ton labs. In order to tack­le the prob­lem of mea­sur­ing from var­i­ous sources of dif­fer­ent na­ture and mag­ni­tude syn­chronous­ly, while re­main­ing flex­i­ble at the same time, ALBA has de­vel­oped a 4 in­de­pen­dent chan­nel elec­trom­e­ter. It is based on tran­simpedance am­pli­fiers and in­te­grates high res­o­lu­tion ADC con­vert­ers and an 10/100 Base-T Eth­er­net com­mu­ni­ca­tion port. Each chan­nel has in­de­pen­dent­ly con­fig­urable range, off­set and low pass fil­ter cut-off fre­quen­cy set­tings and the main unit has ex­ter­nal I/O to syn­chro­nize the data ac­qui­si­tion with the rest of the con­trol sys­tem.
