Costs COSTS in EURO ON DETECTOR Electronics = FEE V4.0 by G.Corradi (SEA), LNF 27/05/16 History : from APD to SIPM. New Granularity. New SIPM array. 1) Engineering Evaluation based from extrapolation on the prototype system. For LYSO and CsI+MPPC 12x12 mm**2. 2) Granularity of LV-HV controller .. Now called MB (Mezzanine Board) is 20 channels. 3) Differential output to be sent to the WD board 4) ARM controller included in MB. DC-DC converter common with WD It includes all electronics close to the SIPM: The amp-HV chips, the MB controller & the cables from ARM3 to APD and from APD to digitizer It includes the HV system outside the DS bulkhead, IFB (Instrumente Feedthrough Bulkhead) It does not include the LV system outside the IFB. This goes to WD cost. It includes all cables from SIPM to MB. It includes all cables from HV to IFB and IFB to MB. Feedthroughs are on Muon Beam Line. Calculation of cabling is done following latest Integration work done by I.Sarra It assumes no VAT. Production will be done to be sent in USA.
