  1. Status of the LAV FEE electronics M. Raggi LNF G. Corradi, C. Paglia, D. Tagnani LNF SELF PVWG WGCERN 25/04/2011

  2. Outline • The FEE components • Status of the FEE production • Prospects for the rest of 2011

  3. FEE LAV VME 9U Remote Control CAN in, CAN out USB Local Control Vth_H and Vth_L test points and adjust trimmers Sum 1 to 16 Sum 1 to 16 Sums 1 to 4, 5 to 8, 9 to 12, 13 to 16 Sums 1 to 4, 5 to 8, 9 to 12, 13 to 16 Sum 17 to 32 Sums 17 to 20, 21 to 24, 25 to 28, 29 to 32

  4. Mezzanine production status • 100 ToT mezzanine already produced • Each mezzanine has two channels • All of them have been mounted • To be tested (electric test and burn in) • Enough to equip more than 5 FEE boards

  5. Sum mezzanine • Sum 4 analog signals • 10 pieces already produced • The boards have been mounted • Needs electric and burn-in tests

  6. Voltage regulator production • Produce ±6V • 10 pieces in production • PCB delivery expected in 20 days • Needs electric and burn-in tests

  7. 9U motherboard production • The Gerber files have been sent to the firm • A first bunch of 5 PCB boards will be delivered at the mid of June

  8. Other equipment • ToT mezzanine test board • Used to test the ToT mezzanine before the installation • Allows to access both PCB sides • Local thr setting boards • Used to set the thr in absence of CPU remote programming firmware • 9U board front panel • Prototype already produced

  9. Future plans • Receive and assemble a first full 9U FEE prototype before the end of July. • Test the system extensively during fall • Validate the FEE before the end of November 2011 • Start a first massive production (1/2 of total) before the end of 2011
