C-Card StatusA C-Card has been developed for use

with the LEGS TPC and VMM1 versions of the BNL peak-finding ASIC

Readout of the C-Card through the FEC Card and MAMMA DAQ program has been successfully tested

Communication with BNL MM TPC card (carrying 2 x LEGS TPC ASIC’s) has been established along with calibration signal and ramp

C-Card Work ListStill longer than desired

Commission ADC section Verify (by local readout) calibration is

working Compare C-Card ramp and MM TPC

ramp Add monitoring and data storage to

MAMMA DAQ (with help from Marcin)

MMFE CardInitially, design front-end card for

full size MM using BNL VMM1 ASICNow, re-trench and design for

fastest to market productNeed to specify by yesterday

Connector type (which MM?) Motherboard/daughter card (Mini)

versus integrated card (Melded) Input protection (NUP4114?) Still lacking some specification of VMM1

Going ForwardMMFE – mini

Pro - take advantage of AIC work Con - two cards slows pace

15

Going ForwardMMFE – melded

Pro - one card Con - other groups could use AIC if

desired

16

Conclusions

Good progress on commissioning C-Card but additional work remains before go-to-market

Desire to converge on reduced scope MMFE card so design and layout can proceed
