Analysis log

Currently working towards installation in the Hall of the target and DAQ - specifically helicity, scalers and BPMs/Raster.

Sept 09, 2005, Friday:

1. Back to analyzing results.
2. Run 2297 gives error - here
3. Still waiting for gains and thresholds for the PMTs.
4. Check out the rates here

Aug 24, 2005, Wednesday:

1. Analyzer problem fixed. All data analyzed. Currently analyzing the results.
2. One of the run (2293) did not have reference channel readings.
3. Shall document the whole process soon.

July 25, 2005, Monday:

1. Made a few more tables for runs 2290, 2291.
2. Get something weird when I tried to analyze runs today using both onlana.C and physics.C. Here's what it says.

July 20, 2005, Wednesday:

1. Table prepared as a map of the actual n20 setup in the Hall. See July 18 entry.
2. Scaled the hydrogen rates to ³He. Got a factor of ~26. But this did not take into account the window thinkness difference and the angle difference for the G_Eⁿ setup.
3. Shall put up rates maps of other comparisons here soon.

July 18, 2005, Monday:

1. Talked to Bodo about simulations and stuff. Talked to JP about the differences in the 4cm and 15cm LH₂ target.
2. The rates table is here (completed on jul 20). This map, currently compares the rates for two exactly similar runs. Neutrons come in from the left, and the columns, from left to right, are v₁, v₂, n₁, n₂, n₃, n₄, n₅. Also, row 1 is bar number 4 i.e. the first row, first column is V1-04-L (for the LEFT table). All rates separately are here.
