Old Lab books in the Mg lab

The old Lab books from 2004 onwards are kept in the Mg lab in the small wardrobe on top of the optics wardrobe which is used for the fiber optic components. The following lab-books were there at the time of this writing (07.08.2017):

Karsten Moldenhauer (01.04.2004 - 09.11.2007)

Jan Friebe (15.07.2004 - 09.11.2007)

Karsten Moldenhauer (03.05.2005 - 07.03.2006)

Magnesium (09.03.2006 - 14.08.2008)

Moldenhauer/Friebe/Riedmann (20.08.07 - 19.01.2010)

Andre Kulosa (01.2009 - 02.04.2013)

Matthis Riedmann (20.01.2010 - 29.01.2015)
