• ++ : SQUID is still tuned, but no biases applied
• ---- : SQUID turned off, not biases applied

ETF taken at 0.9 and 0.8 R_ob, tuning done with gentle tuning. Data at 0.8 was taken first and 0.9 after overbiasing, some bolometers latched when they were overbiased, which is why there are more combs listed for the 0.8 results.

• PB_8.2.1_etf_0.9_gentle.pdf: 90% R_ob
• PB_8.2.1_etf_0.8_gentle.pdf: 80% R_ob. There is a factor of 2-3 in the speed of the bolometers at this point.

ETF was taken for just comb D at turnaround and 86% of R_ob. Then comb was tuned using the gentle tuning script.

• PB_8.2.1_etf_D_Turnaround.pdf: PB_8.2.1_etf_D_Turnaround.pdf
• PB_8.2.1_etf_D_86Rob.pdf: PB_8.2.1_etf_D_86Rob.pdf

ETF taken at turnaround and 89% of turnaround (~80 R_ob). Bolometer tuning done with gentle tuning (nulled IVs).

Noise:

• Noise Measurements done on 2009/02/05 by Peter. Bad actors identified from Francois' measurements on 2010/02/04 and left overbiased. Combs B, F, J, Q, and V have their squids turned on, all other squids have been turned off.
  • Measurement 1, Polarbear_8.2.1_20100205-M1.pdf, Polarbear_8.2.1_20100205-M1_processed.pdf: Bad actors overbiased, other bolometers tuned to 0.9 R_ob, Gd = 2, Tbath = 260 mK
  • Measurement 2, Polarbear_8.2.1_20100205-M2.pdf, Polarbear_8.2.1_20100205-M2_processed.pdf: Bad actors overbiased, other bolometers tuned to 0.8 R_ob, Gd = 2, Tbath = 260 mK

• Noise Measurements done on 2009/02/08 by Peter. All bolometers tuned using gentle tuning. Combs B, F, J, Q, and V have their squids turned on, all other squids have been turned off.
  • Measurement 1, Polarbear_8.2.1_20100208-M1.pdf, Polarbear_8.2.1_20100208-M1_processed.pdf: 95% R_ob, Gd = 0, Tbath = 260 mK
  • Measurement 2, Polarbear_8.2.1_20100208-M2.pdf, Polarbear_8.2.1_20100208-M2_processed.pdf: 90% R_ob, Gd = 0, Tbath = 260 mK
  • Measurement 3, Polarbear_8.2.1_20100208-M3.pdf, Polarbear_8.2.1_20100208-M3_processed.pdf: 86% R_ob, Gd = 0, Tbath = 260 mK
  • Measurement 4, Polarbear_8.2.1_20100208-M4.pdf, Polarbear_8.2.1_20100208-M4_processed.pdf: 80% R_ob, Gd = 0, Tbath = 260 mK

• Noise Measurements done on 2009/02/09 by Peter. All bolometers tuned using gentle tuning. Comb D (a good comb) has its squid turned on, all other squids have been turned off.
  • Measurement 1, Polarbear_8.2.1_20100209-M1.pdf, Polarbear_8.2.1_20100209-M1_processed.pdf: Turnaround, Gd = 2, Tbath = 260 mK
  • Measurement 2, Polarbear_8.2.1_20100209-M2.pdf, Polarbear_8.2.1_20100209-M2_processed.pdf: 86% R_ob, Gd = 2, Tbath = 260 mK

• Noise Measurements done on 2009/02/10 by Peter. All bolometers tuned using gentle tuning. All squids tuned and used except N and W (which have bad or untunable squids), A (latched bolometer on renulling (fine) to Gd = 1, and I (showed large resonance peak in network analysis so not surprising it latched on tuning)
  • Measurement 1, Polarbear_8.2.1_20100210-M1.pdf, Polarbear_8.2.1_20100210-M1_processed.pdf: 83% of R_ob, Gd = 2, Tbath = 260 mK
  • Noise is around 130% of expected, with a few outliers.
  • I have reprocessed the data using turnaround powers from the PB_8.2.1_IV_gent.pdf measurement and the Tc_table_821.ods measurement. Polarbear_8.2.1_20100210-M1_2.pdf, Polarbear_8.2.1_20100210-M1_processed_2.pdf.

Tcs:

• Tc_table_821.ods: Open Office spread sheet of the bolometer Tcs
• Wedge_821_Tc.pdf: pdf of plots for each bolometer's Tc, with histogram on the first page.
• Tc_table_821_2.ods: Same as above, but with two more columns for power at turnaround and G average.

Loop Gain Measurements:

• LoopGainMeasurements821

Notes:

• NA: Notice that comb I has what looks like a short on bolometer 2. This seems to be real and a problem. Overbiasing the detectors, even with the stage at 675 mK produces a resonance peak that can't be nulled.
