Draft Electronics Design for a New Large Cherenkov Detector R. Van Berg
PENN & Large n Detectors • BNL E734 - 1978 • 13,000 PDTs - tracking • 4,000 PMTs - calorimetry • Kamiokande II -1986 • 1,000 20” PMTs • SNO - 1997 • 9,500 8” PMTs Draft Electronics Design
Basic Parameters(From SNO) Draft Electronics Design
Detector Electronics • Base on SNO Design • Need to redesign integrated circuits • Improve a few small deficiencies • Scale from 104 to 105 channels Draft Electronics Design
SNO Trigger Efficiency Draft Electronics Design
SNO Single PE Measurement Draft Electronics Design
Budget Estimate • SNO Electronics and DAQ Capital Cost – • DOE $470k expended through Penn • Chip donation by Northern Telecom ~ $100k • Board testing labor - TRIUMF / QU ~ $50k • Development ~ 10 person years (~$2.5 M if costed at lab rates) • Scale from 9500 PMT to 50,000 PMT • Well under $100/channel production + R&D Draft Electronics Design
Budget Scope • Previous totals include: • PMT volt divider but not waterproof housing • Front end electronics - discriminator to digitizer • Trigger electronics – local and central • All DAQ hardware • Low and High voltage power and racks • Does NOT include PMT cables – adds about $0.40 / m or $30 / PMT Draft Electronics Design
