Previous Day

	Setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50
	Taking Y-Be data overnight. Last flash at ~6:45.
0900	Tower/MC(H35)/MC sensor/Cold Plate = 31.7/28.1/41/156 mK, Still = 1.11 K / 0.085 mbar, G1/G2 = 120/110 mbar, 1K Pot = 1.50 K / 1.7 mbar, Main bath = 75.6%
0900	Remove Y source from fridge.
0905	Tweak 1K Pot needle valve open additional 5 degrees.
0910	Fill LN2 cold trap Dewar.
1130	Perform mini IbIs on DIB3 in standard setup. After that, unpower DCRC50, remove DSUB pi-filter from DIB3, attach pi-filter switchboard with all phonon related filters turned on, and repower DCRC50. Zap SQUIDs. (Only lines on pi-filter switchboard not turned on are 42, 26, 11, 27, 12, 30, 15, 31, 16, 50, 45, 46, 49)
1220	Perform mini IbIs on DIB3 in with pi-filter switchboard attached and all phonon lines filtered. After that, unpower DCRC50, switch off all phonon lines and switch on all charge lines on pi-filter switchboard, and repower DCRC50. Zap SQUIDs. (Only lines filtered on pi-filter switchboard are 11, 27, 12, 30, 15, 31, 16, 50)
1250	Perform mini IbIs on DIB3 in with pi-filter switchboard attached and all charge lines filtered. Detach pi-filter switchboard, reattach pi-filter DSUB, and repower DCRC50. Zap SQUIDs.
1345	Place Ba source inside shield near detector height.
1350	Set all phonon channels to phonon trace length of 1024 bins (2048 MIDASbins) and charge channels to a charge trace length of 512 bins (1024 MIDASbins). Set both phonon and charge prepulse lengths to 100 MIDASbins.
1352	Check phonon traces. DIB2 pA and DIB3 pC railed, but changing Driver Offset brings them back.
1355	Start 30min Ba series with shortened trace lengths from above at -4/+4 V 0/0 V with FG=5/2/5, OG=3, with 1000 initial randoms, 1000 ending randoms, with no flash beforehand. Trigger on DIB1 phA with threshold of 20ADC bins, with 150 us pileup cut window.
1455	Place Ba source back in safe.
1500	Unpower DCRC50, detach DSUB pi-filter, attach pi-filter switchboard with only pB phonon lines filtered, and repower DCRC50. Zap SQUIDs.
1610	Perform mini IbIs on DIB3 in with pi-filter switchboard attached and all phB phonon lines filtered. Detach pi-filter switchboard, reattach pi-filter DSUB, and repower DCRC50. Zap SQUIDs.
1625	Set all phonon channels to phonon trace length of 512 bins (1024 MIDASbins) and charge channels to a charge trace length of 256 bins (512 MIDASbins). Set both phonon and charge prepulse lengths to 100 MIDASbins.
1630	Check phonon traces. A few channels railed, changing Driver Offset brings them back.
1635	Place Ba source inside shield near detector height.
1636	Start 30min Ba series with doubly shortened trace lengths from above at -4/+4 V 0/0 V with FG=5/2/5, OG=3, with 1000 initial randoms, 1000 ending randoms, with no flash beforehand. Trigger on DIB1 phA with threshold of 20ADC bins, with 150 us pileup cut window.
1710	Set all phonon channels to phonon trace length of 8192 bins (16384 MIDASbins) and charge channels to a charge trace length of 16384 bins (32768 MIDASbins). Set both phonon and charge prepulse lengths to 1000 MIDASbins.
1713	Start 30min Ba series with elongated trace lengths from above at -4/+4 V 0/0 V with FG=5/2/5, OG=3, with 1000 initial randoms, 1000 ending randoms, with no flash beforehand. Trigger on DIB1 phA with threshold of 20ADC bins, with 150 us pileup cut window.
1715	Fill LN2 cold trap full.
1745	Set all phonon channels to phonon trace length of 4096 bins (8192 MIDASbins) and charge channels to a charge trace length of 8192 bins (16384 MIDASbins). Set both phonon and charge prepulse lengths to 500 MIDASbins.
1753	Start 14 hours of 30min Y-Be series at -4/+4 V with standard trace lengths with FG=5/2/5, OG=3, with 1000 initial randoms, 1000 ending randoms, with 30s flash and 25 minute cooldown in between series. Trigger on DIB1 phA with threshold of 20ADC bins and DIB1 qInner&qOuter each with threshold 210 ADC bins, with 150 us pileup cut window.
1755	Place strong 88-Y source in Be disc source holder.
