QTC
• QTC : Charge to time converter– ICRR SK group have developed QTC ASIC
since 2004.– Practical version of QTC will develop this
year.– Production of QTC will go in 2008.
– KEK group is developing ASIC for charge measurements.
Device Candidates (Pipeline TDC)
• TDC for Chambers and Counters– FPGA base TDC FINESSE
• Same hardware with MWPC encoder• 1GHz counting / 1nsec resolution
– 4 different phase 250 MHz clock
• 32 ch / card• Basic components are working.
– AMT-FINESSE• Timing resolution : 0.78 ns/bit• Dynamic range :17 bit• 24 ch / card• Ready
Device Candidates(FADC)
• FADC for CsI(Tl) charge– 65MHz FADC-FINESSE
• 65 MHz sample, 12bit FADC• 8ch / card• Differential input• self trigger-acceptable
Device Candidates (HR-TDC)
• High resolution TDC for TOF– acam TDC chip, TDC-GP2, TDC-GPX
• TDC-GP2 : 50ps rms resolution, 1.8msec measurement range
– High speed TMC ASIC• ~30 psec resolution (aim)• R&Ds are progressing in KEK
