CAMAC Progress Report

                    Week Ending: February 15, 2002
                               Week: 55


Tom Folkers:
     1. I final have all 20 counters in the SMTDBE working and have 
        tested the counter bank-switching capability. 
     2. Repackaging the whole thing in a new rack unit.
     3. Will spent next week getting ready for the DBE's first trip to 
        Mt. Graham.
 
Tom Sargent:
     1. I got my GTK+ 3-D display program drawing paths across the 
        unit sphere in stereo. These are both great circle and non-
        great circle paths from a start point to an end point.  
        Buttons were added to rotate the scene left and right or up 
        and down.  This is all done with vector algebra (cross 
        products and dot products) rather than spherical trig.
     2. Began working on sun avoidance path computation.  The program 
        draw the 30 deg sun avoidance zone and the great circle path 
        from the start point to the end point. It can determine if 
        that path enters the avoidance zone.  First attempt at 
        computing a sun avoidance path is close, but not correct. 

Pete Hubbard:
     1. Traquair A/D arrives  back from low pass filter mods. 
        Installed in rack and tested with DSP.  Had to change some 
        jumpers that the factory had changed to get things working 
        properly.
     2. Helping with DBE testing  to locate counter problem with some 
        channels.
     3. Setting up function generator for testing A/D low frequency 
        cutoff point. The sample clock  has to be increased to allow 
        sampling at higher frequencies to look for A/D cutoff 
        response.
     4. Looked for coax connectors for amplifier board. Still checking 
        for suppliers that have  parts that mate with existing 
        connectors.
     5. Tested a ICL8069 reference diode for noise and found they much 
        nosier that previous reference chips.

Lori Warner:
     1. No Report.

Dave Ashby:
     1. No Report.
