Hi all,
We will have our BICEP2 team meeting tomorrow starting at the usual 9am
Pacific time:
Phone: 1-866-890-3820 (toll: 1-334-323-7229) Passcode:59702175
This week the CMB pipeline telecon will follow immediately after the
main B2 meeting. We will dismiss the main meeting within at most 1h,
but will start the pipeline discussion as soon as it ends--those
interested only in Pipeline meeting should join no later than 9:30am
Pacific.
Clem and I want to try this format to streamline our telecons as this
semester starts. I know at least one of you (Jeff) may have a conflict
between bispud pipeline discussion and the Spider telecon...let me know
if there are other conflicts. If it doesn't work we'll adjust next week.
Walt will resume his informal B2 analysis discussions today--he'll send
a separate email on that.
John

Minnesota: Clem, Stefan
1) Weekly report from Pole [ Steff ]
- SPTR (TDRS Ku) downtime / waveguide repair
* repair worked
* data now fully caught up
- cryo: last Simon transfer, down to 2 Wessingtons
2) Data quality / reduc czar report
This week's report(?) [Randol/Jon/Angiola]
Angiola has been reducing
AI: Randol to review scansets, make report
from last week:
AI: stationarity_ab cut: Angiola to investigate def and hist
20120815I07 -- all cut by stationarity_ab
AI: Jamie T also to look at thresholds, uniqueness
AI: elnod goodness-of-fit cut: Martin
status? -- remains open
status of B2 2012 re-reduction [ Angiola/Randol ]
2010, 11, 12 finished with first pass
having trouble with output checker scripts
Next week's czar: Jon
3) General news and plans
- deployment schedule:
http://bicep.caltech.edu/~spuder/schedule/A-039_FY13_deployment.html
- November/December measurement plan
Basic tasks:
* Nov: far field source cals, sidelobe maps
* Dec: in lab cals, FTS
Zak building a new Keck-dedicated FTS to be also used
for BICEP2 this fall
AI: Randol, Colin to put together
a more detailed plan
AI: Clem, Jon to get feedback
from USAP, update list
AI: Jon to get list of
thermal measurements to Randol, Colin
4) Analysis pipeline news and plans
- next pipeline telecon: today 5pm/4pm/2pm
- thermal analysis update? [ Jon ]
Has rewritten paper draft.

Telescope:
----------
- One pointing schedule
- Number of non-fatal MCE errors
- LFB cam dropped out a few times
Weather
--------
- Good
Cryogenics:
-----------
* Tracking spreadsheet at
http://bicep.rc.fas.harvard.edu/bicep2/south_pole_helium_usage/Summer_2011_…
* Kathleen's Cryo Sitrep:
LHe:
• Approximately5200 liters of useable LHe remain in the Wessington dewars.
• Approximately 250 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: 6 tanks are at 17.2 MPa
(2500 psi), one tank is 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 tanks is at 6.3 MPa
(900 psi), one tank is at 3.1 MPa (450psi), two tanks are at 1.4 MPa
(200 psi), two tanks are at 1.0 MPa (150 psi), and one tank is at 0 MPa
(0 psi).
• Vent GHe from the LHe transfer was compressed into the storage tanks.
LN2:
• The liquid nitrogen plant tuned off all week
• Approximately 250 liters of LN2 are currently stockpiled on station.
Analysis/software/computers:
----------------------------
- Updated firewall and cryo monitoring computer for upcoming pen test.
- TDRSS Ku back in business, fully caught up with data.
Cheers,
Steffen
