Mission Who’s Who
Design & Support RoleProject Examples‘Online’ Role
Mission
The Fast Electronics Group provides the expertise and facilities necessary for the design and development of fast analog and digital electronics required for the experimental programs, and assures that the custom electronics hardware developed and installed for the experiment areas are supported with expertise in field diagnosis, repair, and calibration ability.

Group Leader
‘Custom’ electronics designed for experimental programs (and other groups) as required by Staff and Users.
Analog and Digital circuit simulation
Computer Aided Engineering/Drafting (CAE/CAD)
PCAD, Mentor Graphics, HyperLynx, AutoCad
Field Programmable Gate Array (FPGA) Development
Xilinx, Altera, Aldec – Synthesis, simulation and verification
Circuit prototype development and fabrication
Full assembly and testing provided for final designs
Continued support/upgrade and repair of custom designed electronics
Essential Design & Support Functions
Specification development and consultation.“I need a special raster power supply”
“ I want to convert my CAMAC modules to VME64x”
“ Can you make this with a flex circuit?”
‘Triage’ and repair of legacy CAMAC, NIM, VME instrumentation
Thermal imaging and analysis
Field support of various powered card enclosures [ crates ] including custom crates for front-end readout systems.
Additional Capabilities
Project Accomplishments Circuit Designs – ‘Concept to Copper’
• Scores of custom designs produced and still in use
Examples:
F1TDC
Beam Profile Monitor
NIM Modules
F1TDC ‘HUB’
Wire Chamber Readout
Discriminator/Scaler

Latest Designs
Key Challenges
• High speed serial data links:• VXS crates• fADC -> CrateSum -> EnergySumProcessor
• Trigger System distribution• Complex digital circuit board designs• •
Develop !NOW! specifications for a multi-crate test station.
Two VXS crates with crate summing module
Clock/Trigger/Sync modules
Level 1 processor/Global Trigger Processor
Trigger Supervisor and Trigger system distribution
Develop !NOW! Online specifications for diagnostics, triggering configuration, commissioning plan
Ultimately the Electronics Group will be responsible for the custom modules/systems that we design.
During the installation phase, I am certain we will work closely with the Hall D Scientific/DAQ Staff to successfully commission the detector readout system.
