Loose ends from the Spring 2017 run
- Communication issues (missing acknowledgments) between TI and TD
- - new firmware for TI (tip76) provided by William
- (installed on FCAL crates)
- - new firmware for TD (tdp 73), includes some debugging features
- - initially tested at high rate, have to continue with more tests
- F1TDC initialization issues (32 ns time shift)
- - reproduced using the test stand (Ed)
- trying to reproduce/fix using BCAL cosmic trigger (work in progress)
- Calibration constants for fadc250 (new firmware)
- - new code for the clock distribution (Ben), has been implemented and being
- tested by Hai and Ed (so far successfully)
- - additional ADC code will be provided by Ben shortly
- - when ready, the new version will be tested using a single crate setup
- (consider to install on some Hall-D crates, if successfully tested)
- Performance of CAEN TDCs at high rate
- - slows down readout at high trigger rate (R > 70 kHz)
- we don't expect to run at these rates during Fall 2017/ Spring 2018
- - prepared setup for testing (TOF crates)
- Topics for summer
- Understanding (improving) performance at high rate
- - busy distribution (possible crashes at high data rate)
- - performance of CAEN TDCs
- Emulation of the trigger algorithm
- Implementing SSP/GTP readout (Ben)
- calibration constants for fadc250 (new firmware)
- further optimization of the L1 algorithm for high-lumi runs
- TOF trigger
- - already implemented (FDC alignment, hi-pt meson production)
- - may require some modification (specs)
- - test with Play Back
- F1TDC firmware modification
- - (suppression headers)
- L1 trigger simulation
- Understanding (improving) performance at high rate
