Presentation - Wednesday July 13th

Tasks completed:

• Completed the processing of all files for high and low field hydrogen runs
• Transfered all necessary files from the JLab disks to the cache.

Tasks remaining:

• Finish running the data for high field deuterium runs
• Complete the necessary components to calculate the overall cross section

Quick Analysis of High and Low Field Hydrogen Data:



                               High field                                                                        Low field



CROSS SECTION:



Constants:
    Atomic Mass Weight (A) = 2.0140
    Density of Liquid Deuterium = 0.163 g / cm
    Length of target (L) = 24 cm
    Avagadro Number (N_A) = 6.022 x 10²³ mol <sup>-1

Calculated values:</sup>
    N: Total number of events - obtained from the high field deuterium runs (with a cut of egam < 1.75 GeV)
    Epsilon: Efficiency for the high field deuterium runs - calculated from the Monte Carlo simulation
    N_gamma: Number of photons at the target - calculated using the gflux files.



Problems and Bottlenecks:

• Transfering files from the disk to the cache
• Communication

Tranfering files:   
    Problem solved by writing scripts to search out all files on disk that are not in the cache and then queuing these jobs.
   
Communication:
    It remains almost impossible to get in touch with Dr. Tedeschi - I have e-mailed him repeatedly about the Monte Carlo simulation code but to no avail.
    Wang also remains difficult to get in touch with.
