Maser: A. Bauch will take care on that S. Sauer: * PCF is ordered: will arrive this week * OXCO behaviour checked after switching off and on again and also with backup upc * gps reciver on/off behaviour checked Atom Lab: * Laser 2 TA changed, translation stage for the zylindrical lens implemented * 50% through fiber due to new Diodes: beam shape more elongated, since than problems with fiber coupling, * new pc for Xabbu3, money will come from vlbai, * Balcony still not allowed to enter, we will prepare everything for the worst case, discuss with Ernst * no Notstrom availble (power is supplied by batteries) Quench laser: * got rid of frequency jumps by implementing new temperature controller at the diode (from kmk design to thorlabs) * intensity fluctuations removed by aligning the polarization to the fiber * Beam height aligned * Waldemar calculated scattering rate to 1k at 20mW and 350um. 2nd Atom lab: part will go to QG, Saturation spectroscopy to Main lab, discussion an Wednesday with Ernst on that Next meeting: 6.01.
