L2TS and Plan for Integration Cheng-Ju Lin Fermilab Pulsar Meeting 06/11/2004
L2TS Pulsar Board (Phase I) TS Receive L2 trigger decision from PC Send L2 trigger decision to trigger supervisor TS broadcast L2A/L2R to all front-end crates b0xft00 b0cot00 b0fcal05 On L2A, receive TL2D bank Send TL2D to the DAQ stream upon L2A Firmware for Phase I summer commissioning has been written (Sakari) First round of testing shows the firmware is working well In the process of integrating with the PCs
PC L2TS TS Test Setup We have setup a mini-DAQ system in the test-stand room. L2 Trigger Decision + TL2D Bank (Phase I) L1 Trigger Data TS L1A L2TS Pulsar Pulsar TX (SLINK fiber) PC (SLINK fiber) TS handshaking (sending L2A/R, ROL, Buffer #) Running algorithm Random L1A preFRED/ FRED
Mini-DAQ (supports 8 test-stand crates) RXPT TXPTTS Pulsar (L2TS) FRED (GL1) preFRED Greg F., Andrew M., Michael S. and Bill B. did a tremendous job getting the different boards to live happily under one roof.
“Loop” Status We have achieved the first milestone with the closing of the “TS PC L2TS TS” loop: - Still need to test the loop with high rate and larger data size to look for low level problems - Still need to test the TL2D DAQ path The next major milestone is to bring Daniel’s control/monitoring node into the “loop” closing THE loop. With “THE” loop fully tested in the test-stand, we’ll be ready for the trigger room.
Summer Integration Plans (1) While we are still testing “THE” loop in the test-stand, we’ll start replicating in the setup in the trigger room (L2TS and Slink TXs in lower alpha crate, PCs on the 3 rd floor). (2) Repeating the same set of test-stand room tests in the trigger room using the real sparky and TS. Can be done in between stores. (3) When the upstream system is ready, we’ll swap the SLINK fiber and send real data into the PC. Proof of principle: use the L2 Pulsar setup for L2 torture and cosmic data runs in between stores. (4) Parasitically running L2 Pulsar in beam (compare alpha TL2D with Pulsar TL2D). In this configuration, L2TS output cable to the TS is dangling. (5) The final step is to plug the L2TS output cable to the trigger room TS in beam run.
