RICH ELECTRONICS BASELINE / INTEGRATED

• BASELINE
• FE LV electronics located inside the detector
• DRB, HV supplies, Slow Control CDDC on crates
  around the detector

• INTEGRATED
• FE (LV DR) boards located inside the
  detector
• HV supplies, Slow Control CDDC on crates
  around the detector

• INTEGRATED
• Total power saving (8 W / 10 W)
• Weight reduction (8 Kg)
• Reliability
• More dissipation inside the detector (10W / 12
  W) ! ! ! !

• Other proposal
• Reallocation reduction of Slow Control boards
• Reallocation of HV supplies

• CRATE MECHANICS REMOVAL
• CDDC Location ? ?

BASE LINE STATUS

• RDR
• EM produced and assembled _at_ CRISA
• under test _at_ CIEMAT
• LVPP
• EM standard size produced assembled _at_ CRISA
• under test _at_ CIEMAT
• EM corner size produced assembled _at_ CRISA
• under test _at_ CIEMAT
• CRATE MECHANICS READY

• If BASE LINE is adopted
• Finish functional test
• Back Plane Production
• QM production by CRISA and qualification

3
INTEGRATED STATUS

• RDR_LVPP EM mounting testing _at_ CIEMAT
• Cabling analysis on mock-up
• Waiting for Thermal studies green light

• If INTEGRATED is adopted
• Functional test on CIEMAT module
• Define final cabling
• QM production by CRISA and qualification

INTEGRATED JINF LOCATION
Status Be host by another crate Other
considerations Integrate the JINF inside the
RICH

• JINF ? 2CDDC (1Nom 1Red), as far as CDDC very
  has a similar scheme to CDP
• the possibility of housing the JINF 1CDP on the
  RICH corners was consider.
• Reduced cabling from inside to outside the
  detector 60 cables ? 20 cables
• 2W dissipated inside the detector
• more complicated internal cabling
• possible modifications on JINF

5

• JINF located in two opposite corners

Not enough space for the required connectors (30)
inside the board
CDP
CDDC
CDDC
6

• One CDDC per corner

CDP
CDDC

• Very complicated cabling
• Adequate the signals from J-Crate
