ALPHA-2

Rebuild midas:

• cd ~/packages/midas; make clean; make cmake -j
• restart mlogger, mserver, mhttpd, lazylogger

Rebuild frontends:

• fevme: ssh alphavme04, cd online/vme, make clean, make, restart fevme
• SVD bias P.S. fecaenr14xxet.exe: cd packages/frontends/fecaen14xxet, make clean, make, restart fecaen_hvps01
• felabview: no update
• super_felabiew, feXSequencer: cd online/src, make clean, make, not sure how to install to ../bin and restart.
• feGEM: cd online/feGEM, make clean, make,

Clock distribution:

IO32 internal osc (IO32 has no external trigger input) -> 2x LEMO NIM output 20 MHz ->
-> TTC1
-> TTC FP_Ext_TrigInput1 (VETO_IN LEMO1A) -> 20 MHz PLL -> PLL1_20MHz -> mux -> mux_clk -> pll_20MHz -> (ADC clock LEMO5A)
-> VF48 20MHz clock daisy chain, 4 VF48 modules
same thing repeats for the 2nd TTC
-> TTC2

TTC functions:

• Downloading VA1TA configurations (BOOT control)
• Control of calibration pulser DACs
• Sequencing the readout of the VA1TA analog multiplexor and VF48 trigger
• Processing VA1TA TA outputs and generation of NIM trigger outputs
