Sondrestrom Lidar Operation Log


Operator(s) : Christian, Have, Pedersen, E.Guðmundsson
Purpose : Rayleigh and Na data acq.
Date(s) : 070605 - 070605
File(s) : L20070603_002 - L20070605_001
Comments : Best profile is not acceptable.
Optimized HW plates position verified.
Frontend iris (Tube) should be checked with respect to collimated RX entrance
signal.
New iris mount will be fitted.
Next exp. the chopper will cut through optical path from opposite direction.
Next exp. will be with simplified setup (Only frontend iris and without chopper)
The reference noise count is approx. 400 and the aim is approx 800.

Also, adjustments to the daystar filter mount will be made.

L20070605_00103:00:02Best profile with current system setup is not quite good enough0cp
There will be some work on simplifying the setup.
A new iris mount is necesary.
