	Setup: DIB1/3/4 → 3.2 MHz filters 2/3/1 → cable 3/1/2 → gender changer 3/?/2 → HVConn 1/3/2 → HV 1/2 → DCRC55(1)/DCRC50(3) 1.1kV → NaI B/C → Ortec 452(gain=5, shaping = 6 us, output=10V) / Ortec 575A(gain=10, shaping = 3us) → x10/x10 attenuator → DCRCX(4) DCRC33(2) → kepco 1kV power supply → HV input
status:	Took 22Na data overnight at -80V.
0940	Sequence is still going but it looks like data is not being copied from /livedata to /byseries. Looking at Programs, Logger is on but I don't see any “lazy logger”, I think that's supposed to be running too.

0945	Restart MIDAS. Now lazylogger is seen when you do a ps (see below). And Programs shows Lazy_0 running. Start DAQ programs. Sequence starts up where it left off. Data is being copied to /byseries.
