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, TTC2
• -> TTC1
• -> VETO_IN LEMO1A
• -> FPGA pin FP_Ext_TrigInput1 -> 20 MHz PLL -> PLL1_20MHz -> mux -> mux_clk -> pll_20MHz
• -> FPGA pin PLL_20MHz -> FP_ADC_CLK -> LVDS_ADC_CLK -> ADC clock LEMO5A
• -> VF48 20 MHz clock daisy chain, 4 VF48 modules
• -> VF48 clock input -> PLL 20MHz-to-60MHz -> 60 MHz ADC sampling clock

same thing repeats for the 2nd TTC

• -> TTC2
