  • Bigbite DAQ status ( Eric )

-slide here -Eric should look at existing PODD classes for shower to decode Fastbus -Shower trigger  : less than 200 ns -test trigger lines : 190 ns


  • HCAL DAQ status ( Scott )

-2 crates : 1 VXS crates with FADC and 1 VME64X with F1 and FADC -see cosmics in both crates in FADC , missing in TDC ( need to check new timing with 2 crates ) -resolution lock issue with F1, might be overheating -add blanks to improve cooling -reduce resolution of F1 to see if problem goes away - latency from TI ( OT2 is prompt output less delay down to 200 ns)

  • UVA GEM status (Byran / Kondo )

- 3 VME crates in clean room with TI ( 2 VME and 1 VXS ) : 2 planes per crate , 1 TI and one fiber, need 1 TI with two transceiver -using CODA3 -wiki with information on wiki : -computer ready soon -3rd (VXS) crate with SSP and MPDs

  • SSP readout ( Ben )

- 16 MPD for 1 SSP to be tested - all transceiver and fibers on site - test radiation hardness of transceivers and fibers

  • BCM digital :

- daughter board design done, need to make prototypes and test


  • Certification of electronics : need to check with Ed Folts ( Nilanga question )
