Jan Mayen - Mission #1 of Iceland  [05/27/96]  
Sean Warren's Data Log
Slicer



Mission included: Barry Coyle, Jim Garvin, and David Rabine


Note:  Until Barry Coyle arrived in Iceland to re-align the laser transmitter, all measurements were taken with the beam being bounced off the tube in some fashion so that it was still in alignment, but the beam size and shape would be unknownable.  All measurements between 05/10/96 and 05/27/96 are suspect.  05/27/96 and beyond was great.

Also Note:  When not stated, you can assume that the system being run had the following elements:  80Hz, 1slick80.exe, divergent lens, no scanning

NOTE:  Laser has melted ribbon cable and cooling teac's in laser are no longer functioning... cannot run laser to keep warm without over heating.  If I don't run, it will have no power left for any more data...I am going to run it at 10Hz to keep firing, but not over heating.
