Testing and Configuration for VMM1 on the mini-MMFE at Brookhaven National Lab Sarah Jones (Arizona), Jessica Metcalfe (BNL), Charlie Armijo (Arizona)

Testing the mini-MMFE Adapter card, v1 TDO and PDO FPGA VMM1 ASIC USB connection

Timing Example for New Setup At peak, ramp begins for timing between peak and readout signals. Slope of ramp gives conversion from voltage to time. Ideally, slope = constant

Noise Measurement Example Noise measurements with RMS vs peaking time for various Gains (0.5, 1, 3, 9 mV/fC) CHN 64 noise:

Plans Testing of the mini-MMFE was successful with only minor issues Next steps are to: Assemble remaining 10 mini-MMFE (left-handed) this week and begin testing at BNL late next week Fabricate V2 adapter card (with LVDS to RSDS conversions) this week May not be needed but will have it anyway Begin layout of right-handed mini-MMFE Few day job

Issues with Current Boards Digital ground and digital signal switched ena and wen signal pins switched a0-a5 address pins switched in order TDO and PDO signal connectors switched Ribbon cables (for 60 to 60 pin) are difficult to construct Silkscreen issues

VMM1 Readout Plan

New “C-Card” Existing BNL DAQ board with ADCs and Cyclone IV for readout, configuration AZ Adapter Card (V1) AVNET LX9 with Spartan 6 FPGA for ethernet connection to switch

DAQ Status and Plans UDP datagram sent between client and server at Arizona Can be used for testing with Mamma DAQ UDP datagram sent from LX9 at Harvard Will be tested at Arizona this week Communication between Jack’s BNL DAQ board and LX9 progressing well Integration at BNL 7/2 – 7/11 including George Iakovidis et al. Need meeting with Marcin on Mamma DAQ end

UDP client and server are running on a LAN. UDP Server UDP Client UDP Datagram ACK UDP client and server are running on a LAN. We have sent a big-endian datagram via the UDP client on the laptop, which is a sample event in the current format. We have received the datagram on a desktop computer and unpacked three 32-bit words of the event to correctly obtain each address, timing, and amplitude included. The server sends an ack, which in this case completes the transaction. The Spartan6 LX9 will replace the laptop as soon as we get the compiled image. Boost, C++, ASIO Made up data, time, amplitude of event and send it through system for test
