Tasks:

1.) Run Tables (Alex)

2.) ASCII file generation (Sam)

3.) TDC -> time -> Neutron Energy calibration (Sadiq)

4.) Reproducibility tests (Dale, Alex)

a.) Gamma & Neutron rate change

b.)NaI/Ref -vs run number and Target (Wheres de photons)

c.) Asym the same between detectors in same run and same detector in different runs

5.) Threshold match procedure (Tony)

Did the unpolarized runs on the last day have matched thresholds?

Compare Asym in single run to asym when detectors swapped

6.) H20,C,Si,Pb,N([math]\gamma[/math],n), X-sections Neutron producers? (Jasen, Ariel, Sam)

Black lead shot collimator increased neutron flux by factor 2?

7.) Origin curve Fitting (Valeriia)

8.) U rate estimate (Dale)

9.) Asym -vs TDC (MeV)

10.) What improvement in beam is needed

11.) FFT of N ToF

Tasks:

1.) Run Tables (Alex) (Done)

2.) ASCII file generation (Sam) (Done)

3.) TDC -> time -> Neutron Energy calibration (Sadiq) (Maybe Done)

4.) Reproducibility tests (Dale(busy talking), Alex)

a.) Gamma & Neutron rate change

b.)NaI/Ref -vs run number and Target (Wheres de photons)

c.) Asym the same between detectors in same run and same detector in different runs

5.) Threshold match procedure (Tony(busy writing))

Did the unpolarized runs on the last day have matched thresholds?

Compare Asym in single run to asym when detectors swapped

6.) H20,C,Si,Pb,N([math]\gamma[/math],n), X-sections Neutron producers? (Jasen, Ariel, Sam)

Black lead shot collimator increased neutron flux by factor 2?

Histograms of [math]\frac{N_{ref}}{\# counts from {NaI}(Time measure)}[/math]-vs- ToF for H2O, D2O, MT , no Targ. (Jasen)

7.) Origin curve Fitting (Valeriia)

8.) U rate estimate (Dale)

9.) Asym -vs TDC (MeV)

10.) What improvement in beam is needed

Graphite shielding not lead

11.) FFT of N ToF

12.) Do we need to replace the lead in front of the detectors with graphite to get rid of the high energy peak in ToF spectrum?
