Status of LAV FEE Electronics at LNF: Production & Prospects for 2011

This document outlines the status of the Front-End Electronics (FEE) components production at LNF, covering the remote control, test points, mezzanine production, voltage regulator, and future plans for 2011. It includes information on the FEE LAV VME 9U, mezzanine boards, and voltage regulator production status, along with details on testing procedures and equipment. Future plans involve full prototype assembly and system testing for validation before a massive production kickoff by the end of 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
