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.
