Hi All,

This will be the last report from me. Calibration activities have started and somebody else will be reporting on these.

    * 9_CMB_36c_dk248_016.sch
    * Aborted in last scan set

Telescope:
----------
- Ran NTD x-talk v2 schedule twice
- Ran CMBdark schedule
- Stopped CMB obs to mount FFFlat

Weather
--------
- Mostly good, clouds and overcast periods prevented pointing schedules during the fridge cycles

Cryogenics:
-----------

* Tracking spreadsheet at http://bicep.rc.fas.harvard.edu/bicep2/south_pole_helium_usage/Summer_2011_Winter_2012_NPX_Cryo_Tracking.xls

* Flint is here

* I investigated the much higher than usual vent gas recapture rates in the previous two transfers. Found that Kathleen didn't completely close the valve on tank 5. Pressure was slowly equalizing between tanks 5 and 8. Measured contamination in 5, 6, 7, and 8 and they appear clean. Flint will just have to top up tank 5 once we are done with 8.

* Kathleen's Cryo Sitrep:

LHe:

Approximately 2800 liters of useable LHe remain in the Wessington dewars.
Approximately 500 liters of LHe were delivered to BICEP2.
Based on a historical consumption rate of 35.7 liters/day, LHe supplies are expected to be exhausted by January 2013

GHe:

Out of 16 storage tanks for gaseous helium: 7 tanks are at 17.2 MPa (2500 psi), two tanks are at 13.8 MPa (2000 psi), one tank is at 12.4 MPa (1800 psi), one tank is at 10.3 MPa (1500 psi), one tank is at 6.2 MPa (900 psi), one tank is at 2.8 MPa (400 psi), one tanks is at 1.0 MPa (150 psi), and two tanks are at 0 MPa (0 psi).
Vent GHe from the LHe transfer was compressed into the storage tanks.

LN₂:

The liquid nitrogen plant turned on 28 October 2012 and turned off 03 November 2012
Approximately 550 liters of LN2 are currently stockpiled on station.

Analysis/software/computers:
----------------------------
- Firewall crashed again today. Second time now. Will investigate.
